Kevin,
I also recommend the Sinclair SRL229 having used them
at my 147.180 repeater site at 11,000 Ft for over 30
years now!
I have had one apart and the radiating elements are
made of solid brass rod with phasing coils between
elements.
The ends of the rods are drilled out for the phasing
Hello,
I have 2-Sinclair VHF 140 MHz to 160 MHz (I think) 4 dipole 6 DB gain
antennas, 2 UHF DB 410 and two DB 800 to 860 MHz on top of my 500 foot
commercial tower. I have never had any problems with them except the mounts
on the Sinclair antennas were not tightened enough and they are leaning

Skipp, you might consider sending the list email to a regular email account
instead of viewing it on the yahoo groups site. Even if it's just some
freebie one. Yahoo doesn't chop the senders address in that case.

Hi Steve,
Thanks for the heads up... it's a great idea,
but would require numerous Email accounts
to keep the inbound messages under control.
That's when one is a member of more than
one or two yahoo groups.
Those posting should at least know many of
us read the group through yahoo on
Ah, ok.
I won't go looking for that diagram.

Mathew, I don't remember exactly what the problems were with your
earlier posts, but I understand that you have an adjacent channel user
with 9kc deviation, right? If so, then cavity filters will have
absolutely no effect. The passband of even large cavities is far
wider than the 15 or 20 kc
Crystal Filters do quite a bit, but they are
very expensive and have more than modest
insertion loss. Piezo Technologies makes them.
You can obtain improved IF crystal filters from
Com-Spec. They help, but tend to be less of a
problem solver vs the antenna lead Piezo filters.

I don't know what a 74-70 is - my old TXRX catalogue does not list it.
But I have converted a TXRX 4 can multicoupler to a 2m BpBr Duplexor for
a local club quite successfully. I will discuss it with you off-list if
you are interested.

I am looking for a print or detailed description of how Motorola

didn't get a good print out on my end. I remember seeing a portion of

Mathew,
When considering RF preamp gain, more is not always better. I'm not
familiar with the ARR preamp, but if it is a GaAsFET amplifier with 17
dB or so of gain, and your bandpass cavities have 1.5 dB of insertion
loss, I would put either a 6 dB or a 10 dB coaxial attenuator on the
output of
it is done with a special power supply made for that use.

Side mounting is going to be much better mechanically, assuming you bracket
at the top of the antenna as well.
If you can afford to give up coverage to the back of the tower, this is not
a bad choice.

Just want to get some input on what users think.
What do you mean by 'it didn't help'? Did the SWR stay the same? If so,
the arrestor is bad and must be replaced. If not, you may have a bad
connector or jumper somewhere. Make sure you eliminate everything else too.

It was first on 82-70, then on 22-82. It was WR6ACD
