Re: Topband: Shunt feed procedure?

[kr9u]

Kenny,

I am shunt feeding a 120 ft. tower on 160 with 8 ft. mast out the top with a 
432, 20 el antenna at 128 ft.   At 115 ft. is a 2 el 40.   You can see it on my 
QRZ page.
Measurements show it at 122 degs.   I am using a single wire attached at 70 ft. 
 The spacing from the tower is about 2 ft. and does change the SWR.   

Jim - KR9U



-Subject: Topband: Shunt feed procedure?

Hi All,  we’re planning on gamma  loading a 130’ tower with a stack of StepIR  
antennas using a cage for the shunt wire. We have modeled the tower. Question: 
is the model sufficient to determine the gamma wire height?  Or is the 
procedure to use a single wire to per the model height first to find the 50 ohm 
point and then build the cage to fit the length?

Also, any tips on shorting the elements on the StepIR dream beam so they won’t 
arc?  Any anecdotal info on StepIR antennas on the shunted tower?

Re: Topband: 4.3 -10 Re: Rather use N-type (was Re: The answer to PL-259 soldering/reliability problems)

[Steve Maki]

It's doubtful that 4.3-10 will ever be popular for larger cables, 
because large diameter feedlines in the cellular industry are no longer 
being installed. It's all Remote Radios behind the antennas, and short 
1/2" jumpers.


So be happy with N or 7-16 for your main lines. I recommend 7-16 of course.

Hi Frank,

4.3-10 can't be so expensive if compare new to new. E.g. 7/16 to 4.3-10
"brand" adapter bulk price is 10-15% higher than N to 7/16, also price
of few meters prefabricated "jumper cables" with 4.3-10 vs 7/16 differs
in 10-15%.

I hope it revers soon as and also cellular antenna life span is getting
so short -down to few years according some report - so we will have lot

The question is if they get popular for other cables than 1/2 and we get
right price there.

Hello Arunas,

While the relatively new 4.3-10 family of "mini DIN" connectors is
far superior to any connectors we've discussed in this thread, their
cost is nearly ten times higher.

On the other hand, the much bulkier 7/16 DIN connectors offer
similar high performance and they're widely available at much
more affordable prices. For example, do this Google search

7/16 DIN connector site:ebay.com

Hi Tree,  many thanks for the background on the dream beams!  QSL on the 
effective tower length. ON4UNs book says aunt feeding will work up to 140 
degrees. My friend is doing the modeling and it’s hard to imagine we’re more 
than 120 degrees. We’ll see. Fingers crossed

Re: Topband: Shunt feed procedure?

[Tree]

Some anecdotal info on use of Steppir antennas on loaded towers.

I have never heard of anyone experiencing arcing.  This also includes using
other antennas with isolated elements (like KLM).  There just isn't going
to be a potential difference.

I have helped several locals load their towers with Steppirs on them - and
nobody has had an issue.  ZL3IX uses an original Monster - as do I - on a
loaded tower.

When I first did mine - I purposely connected the elements at each end of
the boom to the boom electrically.  This was on a 77 foot tower and I found
putting the Steppir on 30 meters yielded a good mach with a gamm up about
45 feet.  However, I had one issue that might - or might not - have had
anything to do with 160 meter operation.  After a few months - both motors
at each end of the boom were frozen.  This was a mechanical issue.  The
antenna I put up was used - and had many miles on it - so it is hard to say
what was the root cause.  I did have some lightning that could have been a
contributor - but how connecting the boom to the element would affect the
motors is beyond me.

After fixing the motors - I decided to home the elements and use a loading
wire off the tower of the tower.  My new installation doesn't need any
loading from the elements - since my tower height is now 97 feet and the
boom alone is enough top loading.

I still feel your tower is too tall - but we have already talked about
that.  I do not know if modeling really works for this - but haven't
seriously tried it.

Topband: Shunt feed procedure?

[Kenny Silverman]

Hi All,  we’re planning on gamma  loading a 130’ tower with a stack of StepIR  
antennas using a cage for the shunt wire. We have modeled the tower. Question: 
is the model sufficient to determine the gamma wire height?  Or is the 
procedure to use a single wire to per the model height first to find the 50 ohm 
point and then build the cage to fit the length?

Also, any tips on shorting the elements on the StepIR dream beam so they won’t 
arc?  Any anecdotal info on StepIR antennas on the shunted tower?

Topband: 4.3 -10 Re: Rather use N-type (was Re: The answer to PL-259 soldering/reliability problems)

[ly2ij]

Hi Frank, 

4.3-10 can't be so expensive if compare new to new. E.g. 7/16 to 4.3-10
"brand" adapter bulk price is 10-15% higher than N to 7/16, also price
of few meters prefabricated "jumper cables" with 4.3-10 vs 7/16 differs
in 10-15%. 

I hope it revers soon as and also cellular antenna life span is getting
so short -down to few years according some report - so we will have lot
of dismounted stuff soon ;) 

The question is if they get popular for other cables than 1/2 and we get
right price there.
