Hi All,
And the winner is. Door # 2.
Put the 2 meter vertical up on the stick at the end of
the hard line, the desense was worse!
Perfect match at the feed line end.
Took dummy load put on far end of hard line no desense.
Guess it is the proximity to the antenna. Although about 100',
look at all your repeater sheilding and interconnect cables from repeater dto
duplexer and those cables. you appear to be getting signal ingress through the
recieve side somehow. I have had antenna on top of the repeater using a mag
mount and not had problems. Good luck this is a tough problem
In the real world... it's only the responsibility of

types means they are within the normal legal
parameters/operation/scope of the license

Hi all,
We have a puzzling problem with our two 2m repeater networks.
They all use Mitrek's on 2m and Maxtrac's on UHF for linking; each network has
a handful of satellite repeaters, all on diff. 2m freqs of course. All
satellites use one of two UHF freqs for simplex linking to their hub

I heard a similar problem with an ARES net in Oregon. One of the county EOC's
had installed a high rooftop antenna for the hams, and could be worked on
simplex for many miles, but into the main ARES 2m repeater it sounded as you
described, to the point it was unintelligible. It was fine into

Been there and done that!
My guess is that you have corrosion in the antenna on top. The corrosion
makes a good wide band rectifier of your transmit power and produces
sufficient noise at your receive frequency to get back through your duplexer
and into your receiver as desense. Actually,
You mentioned 100 ft hoz separation, I don't think that is enough, but don't
have a chart handy where I am now. Sid.

I guess it could be corrosion at the antenna, but the one that

I forgot that you spoke of 100' antenna separation. This suggests no
duplexer and two feedlines. The meat of my story is still good---a corroded
transmit antenna is capable of making and radiating allot of receive
frequency noise ---even with between antenna pattern attenuation, there
Hi Scott,
The 100' of separation is from the repeater to where the
antenna is located.

I still think it may be something in the vicinity of the antenna. What kind of
building is the antenna mounted on/above?
You've stated that the repeater is in a metal pole building that's 100ft. away
from the antenna. It's been mentioned before in this thread, but that could be
a noise
The antenna is on the top of a small wooden storage building.
A mast is placed up against the peak of the roof, and the 224
is on top of that.
The metal building that the repeater is in is my garage. Very
plain, no air condx, AC power runs around the pearlings about
4' off the ground.

Does anybody use anything like Caig's DeOxit products? I'd treat each every
connector in the system, inside outside the electronic cabinets, e.g. coax
connectors.
I find it works extremely well, indoors out. I've been using it for years.

Tim,
I believe you stated in a previous message that the antenna was 100 feet
away, horizontally. That is light years away from it being 100 feet ABOVE
the repeater.
