Speaking of tuning the duplexers that is. I have seen it done both ways

I suspect the 50 Ohm load is pretty much purely resistive. The antenna may
have reactive components that even with a very low standing wave ratio, may
cause the shutback circuit to do so. Sometimes a different length of
jumper cable may change the reactance vector. Wonder what the Antenna and

I have experienced duplex noise with lengths of RG-8 and RG-213 that
were pretty old and the braid lost its shine. I learned this the
hard way when blaming antennas for duplex noise when indeed it was

All,
Happy, Merry and all that good stuff. I left my parts

that someone else wanted it more than I did.
Unfortunately, I had all of my remaining feed-through

Hi,
I tuned up a Mitrek for repeater use. Everything went fine and I set the
power level to 65W into a 50 Ohm load. When I connected the Mitrek to the
actual antenna, power output was reduced to less than 30W. Why would that
be?
There's no reflected power to speak of using either 50 Ohm load or

Got a number in mind for the UHF mobile duplexer?

On one set I have it going to a splitter and then to two RG6QS jumpers
