The repeater is actually outputting (and is coordinated for) 250 watts
into the duplexer. Subtracting the duplexer insertion loss of 1.5 dB
(or 29 %), I get about 175 watts to the bottom of the feeder which I
lose an additional 1/2 a dB or so, so I really get about 158 watts to
the stick (Sinclair SRL-229) which has a rated gain of 6.1 dBd, so my
ERP is about 650 watts. The antenna will handle 300 watts, so I'd need
to run over 400 watts for that to be a concern.
I have run this station for short periods of time at the 330 watt level
for testing. There isn't much difference in ERP between the 250 and 330
watt level, so I choose to save on the electric bill and keep the
coordinator happy and run it at the 1/4 kilowatt level.
