Re: [Repeater-Builder] Re: Bad adapter

[Wayne]

  Cannot see any braid without undoing one of the N connectors on the RG214  
jumper.
  Connectors are evidently not Amphenol, unless they didn't mark them as  
such. The cable says RG214/U. Connectors marked 74868 UG-1185/U Seems to  
be good quality.
  No leakage that I can tell, and zero resistance from one end to the  
other, so should be good to go.

Same difference if they cut the light power lines. Guess anyone with a

My way is prevention. Once they hit that Heliax, they don't be

any more tower sites - preventing the next guy and likely saving some of

Your way is just "passing the problem on" to the next site. (not meant

Show me a "quad" 555 in one package.  There was one once actually, the 
558.  Was sold by Radio Shack.  Can't find them anywhere now, though.

Show me a 555 used as an audio amp.

I can build a complete COR/hangtime/TOT/audio interface using one LM324 
(actually, nowdays I prefer the TLV2374 - less crossover distortion & 
better rail-to-rail performance).

555s/556s certainly have their place, but for something as simple as the 
above I find the rail-to-rail op amp more convenient & straightforward.

RE: [Repeater-Builder] CTCSS Filtering and Micor

[Thomas Oliver]

If you are using correctly installed stock micor pl decoder board and you are 
taking your audio from the audio squelch board pin 7 (preamp output) the ctcss 
will be removed and the audio de-emphasized at this point.  You would have to 
mod the controller for de-emphasized audio.

If you want to filter raw discriminator audio you could probably get another pl 
decoder board and feed the raw discriminator audio through the filter on that 
board.

I am not sure if this will work or not because the raw discriminator output is 
a low level high impedance signal and the filter is being fed low impedance 
audio in its natural habitat.

I am sure someone else can correct me if I am wrong.

There's been a lot of discussion over on the S-Com group about CTCSS filtering. 
I have read several posts about Micor's doing the filtering already.

Here is my stupid question of the day:

If I have a Micor UHF Station interfaced to a 7K following the WA1ZYX article 
on the RB website, Can I assume I am not taking advantage of the CTCSS 
filtering since the audio is pulled straight off the discriminator? Is there a 
different place I could pull it to be filtered?

Thanks!

RE: [Repeater-Builder] More on Copper theft

[Paul Finch]

They obviously did not know the value of the connector and when you consider
the 1/2 Heliax has an thin copper coated aluminum center conductor they
really did not get much.  It also looks like the 7/7 Heliax is also the
solid aluminum type but the resolution is fairly poor when I blow it up to
see if they are solid.

But, they don't know the value of that, and likely don't have any

there are plenty of scrap yards..

BUT, you would think that the first few cuts would have deterred them

While the MSR RF side is Mitrek based, the control shelf is
closer to a Micor than a Mitrek.

Look at 
and scroll down to the section titled "MSR-2000 Station"

Using the model table you need to figure out what you have.

There are three different interfacing articles linked to that page,
and notes on a fourth.

The device under test on the logic analyzer looked utterly normal to 
anyone who's ever had to do that... chip pin clips everywhere!

(But if you're debugging code and it just won't do what it's supposed 
to, because you wrote stupid code and stupidly can't find your bug... 
that pile of clips and the analyzer will save your hide!)

Some of those photos looked like someone was prototyping, but they 
weren't.  There were some funny ones in there, I'll admit!

Just Googling around I found these (no I don't know any of these folks), 
just random Googling for repeater photos...

Re: [Repeater-Builder] More on Copper theft

At my last job we were having copper ground buss bars stolen.  They 
would hit a cellsite and take them all at ground level.  This could add 
up to 5 or 10 buss bars if the site had multiple carriers on it.  The 
fix has been to replace the buss bars with tinned copper buss bars.  It 
will be a learning curve, but when the thieves find out tinned copper is 
worth much less than clean copper they may stop taking them.  Many 
thieves are only interested in $10-20 worth of copper.  That's all it 
takes to buy a dose of drugs and get high.

Others may disagree, but the Polyphaser is only "perfect" if tied to a 
properly planned single-point or halo/ring grounding system.

It'll offer some protection just stuck on the feedline and maybe protect 
your investment if you have a GOOD ground available for it inside, but 
by mounting it inside, you're allowing the lightning IN.

You want the lightning OUT.

But what you really want is a lightning protection system that allows 
the entire system... the tower, the feedlines, the cabinets, whatever... 
to rise and fall at the same potential.

That said, having it is better than not, I suppose.

There's been so much written on the topic, and done by pros, that I 
won't even attempt to elaborate further.  Polyphaser has some excellent 
information on their website.

Since you said the tower is 22', you're probably not at a commercial 
site.  If you were to pull the trick of bypassing a copper entrance 
panel and bringing that polyphaser inside, you'd definitely piss off the 
other people around you inside a commercial setup, done right.

At home... all bets are off.  Most people don't even have their tower 
grounds bonded properly to their house safety ground, etc.  And when 
they do, they often find they've created problems for themselves at HF, 
since the lengths (especially from 2nd floor ham shacks) are resonant at 
HF, which will drive you batty...

ARRL Handbook and Antenna Book both have some discussion of grounding 
techniques also... for that late night insomnia... but if you ever get a 
chance to see a really well done commerical antenna site -- go get a 
tour.  It's impressive.  (And expensive.)

There has got to be a way to catch and make an example of these thieves.  The

from and require good ID and keep records of who they buy from and be aware 
that the stuff might be stolen.  Regulations as stiff as buying or selling a

[Repeater-Builder] Re: Super Stationmaster Omni Fiberglass Antenna, information

[Richard Sharp, KQ4KX]

Joe,

 

If you look at the PDF from the link that was provided you'll find that it
IS the spec sheet for the 220-2 which is the 142-150MHz version of the Super
Stationmaster antenna.  The 25-299.9 frequency reference you're seeing is
the "category" of antennas that Celwave is putting this antenna in since
it's a VHF band antenna (VHF - 25-299.9 MHz).  Look further down on the PDF
document and you'll find the specific specifications for the 142-150 MHz
version.  No, I'm not aware of a lowband Super Stationmaster antenna but
they do have other models of antennas for lowband that are in the same
25-299.9 category.  The other link showed the various versions of the Super
Stationmaster denoted by the different suffixes (220-1, 220-2, etc.).

RE: [Repeater-Builder] Re: More on Copper theft

[Mike Besemer (WM4B)]

I hope that the initial shutdown time (and any subsequent attempts to
restart) sent a hell of a jolt up the ax!

 

I used to work and airborne radar set that had overload protection on the
magnetron. it took 7 successive misfires before it would shut down fully.
One night while troubleshooting an intermittent problem we'd been having on
an aircraft, I was in the hell-hole doing a visual inspection of the
waveguide and wiring while my partner ran a test on the radar from the
cockpit.  Unfortunately for me, I found the problem. a broken piece of
flexible waveguide that was only held together by the rubber. which broke
when I flexed it.  I felt all 7 of those transmitter pulses before that damn
thing shut done.  

 

I had to have a couple of extra brews that night to ease the pain!

[Repeater-Builder] WTB: Doug Hall RBI-1 for 7330 controller

[no6b]

A friend of mine has a Kenwood TM-331 that he would like to interface to 
his 7330 controller.  Turns out there is no COS output on the 
radio.  Apparently the signal does exist inside it but I'd have to run a 
haywire out the radio to get at it.  The RBI-1 apparently handles the COS 
by using the serial data stream running between it & the radio, so this 
would be a much cleaner way of interfacing the radio to the 
controller.  Having full control of the radio would be nice too.  I don't 
think these things are being made anymore so if anyone has one they'd like 
to part with please let me know.  Thanks.

P.S.: I know the 7330 doesn't support the RBI-1 yet but am confident it 
soon will :)

Re: [Repeater-Builder] 555 Circuits

[Mike Morris WA6ILQ]

I also ran RTTY and had a DXer a few houses away (actually
about 750-900 feet...), only mine was 2m FM and he was
2m SSB.

My audio oscillator was a one-transistor oscillator with an
88mh toroid in the collector, and a feedback coil I added
that fed back to the base.  A second added winding was
the output to the next stage.  A capacitor resonated at
1975, and a polar relay contact added a second cap in
parallel to drop it to 2125.

Anyway, the solution was to switch the added cap
with a FET, which was controlled by a flip-flop, which
was triggered by the output of a comparator chip (the
part number of LM311 comes to mind).
The comparator chip generated a blip at zero crossing.

End result was that the audio tone changed frequency
at zero crossing instead of at random points in the
audio waveform.

Your method sounds more elegant.

  Use of the antenna could be considered theft of services IMO.
  Theft of services covers a number of things.
  Not sure what the 240 volts would do, maybe burn out loops in the

breaker. Possible melt some of that teeny coax the moron was using, ha ha

Mine was on the air - but not active at the time the ax was applied to the hard 
line.  You are my coordinator, but I never did let you know it was down - 
sorry.  But back up now, with a new connector and jumper.

  Somewhere around 8-9 p.m. December 15, The club I belong to  (Mountain
ARC)lost our tower at 2976ft. The area of the site received a blast  of
freezing rain, followed by several bursts of very high wind.  This
created the dreaded twisting effect that has brought so many  others
before it as well. 

We were still licking out wounds from this  loss of 100 Ft Rohn 45, all
associated guys, a db-224, db-408, my Diamond  tri-band, and several
packet beams on several different bands, when I got a  call from MD
state police to identify property.

It seems that during a  routine PC of the area, they caught an
individual with almost all 200 ft of  our 1-1/8" Andrews in his truck,
cut into 3 foot lengths for  recycling.

I was afraid that sooner or later, junkie clowns like this one  would
figure out that hardline was copper. I wonder how long it will  be
until they start cutting the stuff off towers while they are on the
air  and disrupt police dispatch or worse, EMS network? 

At least my personal  site has the feedline routed in a way that it is
not exposed, unless they can  scale the gym roof straight up. (wx3m.info)

Don't forget the old military stuff with the strong vinegar-like smell of the 
anti-corrosive treatment, whatever it was (probably toxic/carcinogenic...)  I 
used to have an old (WW-II) BC-639 aircraft direction finding receiver, 
complete with power supply, control head, headset, handset, manuals and spares, 
all in the original 2x2x3 wooden cabinet with the screw-in pipe legs.  WOW, did 
that stink up the shack!  But you gotta love the way the meters glowed under 
those #47 bulbs...  Donated it to the Scranton/Pocono Amateur Radio Klub when 
we moved to the Chicago area in 1985 - XYL didn't want it in the new house.

[Repeater-Builder] Re: Carrier Control Timer (use the COR-2 circuit)

[skipp025]

Re: Carrier Control Timer (use the  COR-2 circuit) 

The 555 timer is a lot like the 723 (voltage reg) chip in regards 
to a very large variety of available circuit options and layouts 
that simply must obey certain rules detailed in the Mfgrs data 
sheets. Onward... 

The 555 is one of the most useful electronic circuit chips ever 
made. It has a fairly large number of possible simply configured 
mono & astable (cycle) circuit operations. And it's just as easy 
to get lost when trying to use it for specific tasks. 

As in the way of the world... sometimes it's best to see on paper 
how someone else has already applied the 555 toward x-application 
and of course use that circuit (aka "steal") for your needs. 

How that other person has/had completed the interface and trigger 
requirements using combinations of input & reset pins and some 
external support parts like transistors and diodes. 

Working from memory here... the 555 triggers on the rising edge 
of a changing input. The Original Hamtronics COR-2 circuit was a 
fairly well thought-out circuit using a 555 chip for the tail and 
a second 555 as the time-out timer.  And because of the way the 
555 operates with voltage ratios it was fairly free from problems 
with more than modest changes circuit supply voltage. 



Hamtronics moves forward in time with the COR-3 

Moving to op-amps to complete timers and audio circuits was done 
in the Hamtronics COR-3 circuit. 

Both the mentioned Hamtronics circuits not only work very well for 
what they are but the builder/operator learned - picked up a fairly 
clear understanding of how each portion of the circuit works. They 
aren't teaching this type of stuff in school much anymore... and 
you get to build it yourself. Nothing more fun for an electronics 
person than a little of hands-on work with a good set of instructions 
(RIP Heathkit) in hand. 

Of course those of you following the Hamtronics line through the 
years saw the COR-4 circuit with an Eprom for the now on board 
CW IDer memory element. And Hamtronics has the COR-5 unit, which 
is a basic micro processor repeater controller. I believe they 
still offer the cor-4 and maybe the cor-3 circuits. 

You can pick up a lot of information and skill building kits and 
Hamtronics is one nifty way to go... I've also seen less informative 
555 timer chip kits sold by Ramsey, Electronics Rainbow & Jameco, 
which are probably the Velleman brand kits supplied with really 
horible instruction sheets. 

And of course the "555 Timer Cookbook" should be in your library. 

cheers, 
skipp

Oh we notice all right... people wise it can get pretty bad. 

And the equipment odor is not exempt... nothing like the

It's already a big problem with AM broadcast stations

I wonder if amateur equipment insurance covers such

Just make sure the RG-214 is silver-plated.  I had a jumper I used this 
weekend for a 2 meter repeater installation that said "Intercomp RG-214" 
that caused desense when I flexed it, so I replaced it.  When I got home I 
took a close look at one of the connectors & could make out a couple of 
COPPER braid strands.  That jumper got the colored tape band applied to the 
middle, my indicator that it's "no good for duplex".

For some reason I never had much luck with 555s; the trigger inputs were so 
sensitive that they always glitched in my noisy high school-era 
circuits.  I found the LM324 quad op amp to be much more stable & 
versatile.  One section could be the COR, another the timeout timer, & yet 
another the audio amp/de-emphasis.

Re: [Repeater-Builder] Re: Yahoo burp?

[Bruce Bagwell]

It's been awhile since anyone has heard from me, still shaking off the cinders 
from all the "Flames" sent my way!

While those who "Flamed" are right, it was a stupid answer, I have noticed that 
many (Most) times never get the original message of the thread.  

The 2 week old post proves it!  There was even a reply to this very old post!  
While I do not know what is going on, at least it helps explain the "dumb 
posting"  I read several of the threads but either didn't get all the other 
threads, etc. or they came AFTER I sent my message.

Please remember that thread went ON AND ON AND ON.

While had I all the postings I would not have sent what I did, please remember 
all the "Experts" never did agree on this simple matter.  Many even suggested 
to ask the FCC!  While I am new to this hobby I know this well from other 
dealings with Government,  NEVER ask them for an opinion on something that is 
really minor and no one can agree anyway.  Many times, you will not like what 
they tell you!  Amateur radio is supposed to be "Self Policing" and should 
remain that way!  When I studied for my HAM ticket, I was really impressed by 
the fact for once Government is doing what it should do. Set-up a few basic 
rules, provide for enforcement and prosecution for breaking of those rules then 
stay the heck out of the way!!!  The more times we HAMS ask Government for 
answers to really Non-Problems, we invite more regulation to our hobby.

On the same topic of our hobby, while I admit I made A "Dumb Answer", Those who 
chastised me in the group format more than once is no way to build the number 
of HAMS!   Most of the HAMS I have met are older, where is the young blood to 
keep all going after we are gone?  I help to provide Comm. a couple weeks ago 
for the local Boy Scout Canoe Races. I was so impressed when  young Scout came 
to me and said "I'm A HAM!".  I asked him "What is you Call Sign" and he 
replied "Are you kidding! I can't even remember my phone number!"

OK, this young Scout probably didn't use his HAM ticket but at least he had 
one!  I think we ALL need to do whatever we can to promote the hobby to 
everyone we can in particular the young ones!


Just brushing off the cinders!  Sorry about the dumb post. Maybe that is a 
result of Spam Filters, different ISP's, etc.  I would LOVE to know why 
something I sent 2 weeks ago just showed up yesterday!  Seems the same thing 
happens all the time for me, just not quite that late!


BTW, I know 10 meter is basically dead due to the Sun Cycle. However I have 
been given a 10 meter radio, Base and Mobile Antenna. What are the popular 
freq's, modes and beacons for this band?  Hope this question isn't too stupid!  
Just thought about it and have not even had time to search the net for the 
answer.

PSS. Thanks for the help on the Astron P.S.!

Now have that critter working just fine with added V & A meters and a 
resistor/relay "Soft Start"  Meters have been calibrated and re-scaled.  PS 
never pops my weak house breaker and that should help the life of everything 
without the "Hard Turn-On Surge"\

Now I have the 12VDC power to run almost any mobile radio as A Base rig.
Thanks again to all those who helped!

It's already a big problem with AM broadcast stations

RE: Re: [Repeater-Builder] RE: Hijack (WAS: Bad adapter) OFF TOPIC

[n9wys]

You are correct Larry, the act itself *IS* criminal.  But in order to be able 
to successfully prosecute the perpetrator, one needs to be able to show: 1) WHO 
did it, and 2) that there was INTENT.  Without those two, no individual will 
ever be prosecuted.  

Tell ya what - you take the photo Jeff put up, with the info he provided, and 
go to your local prosecutor and ask him if he'd be able/willing to pursue a 
court case without info regarding who (SPECIFICALLY) did it.  (An I mean what 
individual actually cut the cable, not whose machine it's connected to.)  I 
think you're in for a surprise.  Better yet, get out your statutes for wherever 
you live and read the statute on Criminal Damage to Property.  You'll find 
references similar to this (from Illinois law):

Sec. 21‑1. Criminal damage to property. 
(1) A person commits an illegal act when he: 
(a) knowingly damages any property of another without his consent; 

Note where it says "person", "knowingly" and "without his consent".  In IL, 
you'd need to prove these three things before any conviction can be achieved.  
In this instance, "without consent" goes without saying...  Sure, one can point 
fingers at the group who owns the equipment to which the offending coax is 
connected, but until we can prove >>WHO<< cut that cable, there is no criminal 
prosecution.  Sorry...  (Of course, there are grounds for a CIVIL suit, but as 
far as anything criminal - no dice.)

I understand the futility of the situation - and believe me, nobody would like 
to nab idiots like this more than those of us here, but it is apparent you 
don’t deal with the legal system on a regular basis...  NOW PLEASE DON’T 
MISUNDERSTAND MY STATEMEMT - IT IS NOT MEANT AS DEGRADING!!  However, I **AM** 
familiar with the legal system, so I speak from a relative position of 
knowledge.

Now, for fear of having strayed WAY off topic, I will cease any further 
"transmissions" on this subject.

I defer to your obviously superior ideas.  :)

I do think in all seriousness that there should be criminal charges 
in play.  The idea that you cannot show criminal intent when someone 
CUT your hardline is absurd.  The cutting of the hardline ITSELF is criminal.

RE: [Repeater-Builder] Antenna Question

[Paul Finch]

Hello,
 
Like he said, it depends on several things.  You have to consider the
Antennas, power, frequency, split and quality of receiver and transmitter.
On the receiver you have to look at selectivity and on the transmitter you
have to look at transmit noise.  
 
I have 80 feet between my two high band antennas running a 2 meter repeater
with no desense at all and no filtering.  I have seen as little as 60 feet
on an old GE Progress line repeater, the first repeater I ever built.  The
tower was only 120 feet so more would have made the repeater fairly
ineffective.  It also worked well with 60 watts out.
 
If you are using something like a GE Mastr II or equivalent you could
probably go as close as 60 feet with no desense.  If you find you do have
desense or transmit noise problem you can always use a couple of notch
filters to correct the problem with little system loss.
 
Best thing to do is try it and see what happens and address problems later.
That's the fun of Ham Radio.
 
Paul

Re: Re: Re: [Repeater-Builder] Re: Bad adapter

[Ron Wright]

Neal,

Your point is a good one.  We don't know the whole story and many of our 
comments are for fun.  There may be a real good reason why this was done.

I am sure the owner is dealing with it.  It might have been done by the tower 
owner and one might be there free at his blessing.  One could complain, but 
then you might not have a site.  There are all kinds of reasons why this 
happened and for good reasons.

The type of splice would lead me to believe it had to be quick and dirty to get 
something important on the air.

Re: [Repeater-Builder] More on Copper theft

[Bob M.]

It's already a big problem with AM broadcast stations
losing their ground system. Buried uninsulated copper
wire. Find one exposed piece and start pulling it up.

I wonder if amateur equipment insurance covers such
vandalism?

Re: Re: [Repeater-Builder] Re: Bad adapter

[neal Newman]

On a quick Note Ron
If the repeater was for emergency services( Police,fire,ems or during a  storm) 
 ,and was a Must Get on the air at any cost that would save lives. I would 
allow that stupid splice Until I was able to get the correct connectors to make 
the Correct splice.
and that would be the only reason.
Better to be on air with a Crap splice than totally off the air  for a few 
hours If its to save lives...  I know Its a Ham repeater.. how many Emergencys 
are handled by Hams... ALOT

Re: [Repeater-Builder] Amateur repeater ID's

[Ron Wright]

Bruce,

The problem here is IDing with out use of the repeater.

One can make "broadcast" for certain items such as weather info and some 
general interest announcements.

The time thing is broadcasting and I bet deemed illegal technically by FCC 
rules.

However, giving info along with the ID is legal.  Again it is the issue of 
IDing without usage that is the problem.

I defer to your obviously superior ideas.  :)

I do think in all seriousness that there should be criminal charges 
in play.  The idea that you cannot show criminal intent when someone 
CUT your hardline is absurd.  The cutting of the hardline ITSELF is criminal.

Re: Re: [Repeater-Builder] Re: Bad adapter

Larry,

I thought the same thing except I would go for more 240 V...a good old TV 
transformer with about 800V would do.  Also if you stand inside the building 
looking for smoke it would lead to the user of the feedline.  Bet they would 
not do it again.

Another approach is a high voltage, not enough to damage or smoke the 
equipment, but enough so when the tech came to service it got a surprise 
welcome.

This was obviously a poor and botched job.  The RG58 and crummy splice tells 
one this person would not be working at my site.  I would not even let them on 
the property to look.

[Repeater-Builder] More on Copper theft

[Terry]

Somewhere around 8-9 p.m. December 15, The club I belong to (Mountain
ARC)lost our tower at 2976ft. The area of the site received a blast of
freezing rain, followed by several bursts of very high wind. This
created the dreaded twisting effect that has brought so many others
before it as well. 

We were still licking out wounds from this loss of 100 Ft Rohn 45, all
associated guys, a db-224, db-408, my Diamond tri-band, and several
packet beams on several different bands, when I got a call from MD
state police to identify property.

It seems that during a routine PC of the area, they caught an
individual with almost all 200 ft of our 1-1/8" Andrews in his truck,
cut into 3 foot lengths for recycling.

I was afraid that sooner or later, junkie clowns like this one would
figure out that hardline was copper. I wonder how long it will be
until they start cutting the stuff off towers while they are on the
air and disrupt police dispatch or worse, EMS network? 

At least my personal site has the feedline routed in a way that it is
not exposed, unless they can scale the gym roof straight up. (wx3m.info)  

Re: [Repeater-Builder] Carrier Control Timer

[Ron Wright]

Fred,

Are you looking for a circuit that will reset the controller if PTT is active 
for more than a continuous 10 minutes??

If so I have one I designed about 10 years ago.  It is used to reset the 
controller from a continuous 10 or so minute PTT.  It removes the power from 
the controller for about 1.5 second and then reconnects.

I had a few PC boards made of this.  If you like I can send diagram of circuit. 
 Requires a dual op-amp, LM358 with some Rs & Cs and a pass transistor.  It can 
handle over 0.5 amps.  The unkeying, going high, ptt reset the circuit.

If you are looking for something to keep power removed then this circuit is not 
for you.

Let me know.

[Repeater-Builder] Mitrek Consolette conversion

[David]

Okay, so I have a couple extra motorola Mitrek base consolette bases in 
the shed, dying to be used. So I was board, checking stuff out, and I 
cant seem to figure out if there would be anything that would tell me 
if I could place a newer, Maratrac in this Mitrek base.  Reminder this 
is the old style mitrek base station has 4 channel selector, and the 
plugs for the radios are the same but I cannot find a definate pinout 
for the maratrac.  So my question is, can I put a maratrac in a Mitrek 
base?

Re: [Repeater-Builder] Re: Bad adapter

[Wayne]

  Okay, at this point, I have the following:
  100 feet of LD5-50A
  1 Female 'N' connector for same
  3 male 'N' connectors for same, plus an additional male 'N' from another  
source. All for the LDF5050A cable
  At antenna, a 3 or 4 foot 1/2" Heliax jumper, as the connectors for the  
7/8" Heliax are a tad too large to fit the antenna base.
  Antenna on a 23' tower, and about 21 feet up to the end of the jumper,  
which will be used with some bow to allow for  possible movement and being  
able to clamp the 7/8" to the tower so it won't pull on the jumper at all.
  I also have a bulkhead mount Polyphaser which I could, for the time  
being, install at the repeater itself and use a jumper there that is  
RG214, currently between two cans on a 2 meter duplexer. Two foot, long  
enough to exit the bottome of the repeater cabinet and connect to  
polyphaser. I figure about 30-35 feet of the Heliax to get to that point,  
and allow a bit of slack in the RG214.
  it would be simple to use one male and one female 'N' connectors to  
splice the Heliax if I move things later on.
  Some of these connectors might be harder to get later on, and at a maybe  
higher cost that I got them for.
  Low calorie budget from here on, spent too much on the rep[eater already.
  YMMV
