Most folks will agree that a repeater that is working properly (no
desense) having a receiver sensitivity of .35 uV (- 116 dBm) for 12 dB
SINAD, and a transmitter power of 110 watts will likely be fairly well
matched in receive/transmit coverage considering a modern 50 watt mobile
rig.
Now, lets add a receiver preamp on the repeater and increase its
sensitivity by say 6 dB to -122 dBm. Considering the repeater still
operates properly, without desense, this same repeater would now require
480 watts of transmitter power to be matched as above.
That being said, 200 + watts of transmitter power doesn't seem to be
excessive to me, but it depends on what is there to hear the user.
