We have been over this many times. If a system is balanced with a
receiver at -116 dBm running 50 watts of power, then it will be balanced
with 200 watts and a properly deployed preamp adding 6 dB of gain. The
added power level on the repeater transmitter helps with noise that is

I had a vhf repeater up and running for a little while. Had 180 watts out of
the cans and it was pretty well balanced if you had a 60 watt mobile with a 5/8
