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. Kevin Yahoo!
