John,
This is a post that I listed a week or so
ago about a 228. Maybe this will help you with some of your questions.
Rodger,
I have a DB-228 that is mounted in
the center of the Northwest face. The faces are 8 across if memory
serves me correctly. We are at 635 Center of

Good question. I remember hearing a mention of a UHF RCC system still on

I have a repeater with a receiver on 902.4125 MHz and
a transmitter on 927.4125 MHz. The duplexer is a
4-section Bp/Br design that provides 90dB rejection of
the unwanted signal. I measured this by transmitting a
100w signal (+50dBm) into the TX port, terminating the
ANT port with a 500w dummy
Speaking of DB228s and mounting on wide faced towers, about the only
place left to mount anything new on our county EOC tower is on the
faces; it's sticks from dirt to dome all the way up. However, I
haven't seen this done except for the occassional microwave antenna on
an exotic mount.

I wonder if anyone out there has any information on

setup. But I have lost
I tried experimenting with a couple of sig gens, one
on 902.4125 and one on 927.4125, feeding a home-made
coupler. I discovered that the 927.4125 signal needed
to be about 80-85dB higher than the 902.4125 signal to
give me a noticeable degradation on the received
signal. This was on an 800
