What is the effective isotropic radiated power (EIRP) of a repeater station with 200 watts transmitter power output, 2 dB feed line loss, 2.8 dB duplexer loss, 1.2 dB circulator loss, and 7 dBi antenna gain?
Answer252 watts
The losses total 6 dB and antenna gain is 7 dBi, leaving +1 dB net gain. Two hundred watts increased by 1 dB is about 252 watts EIRP.
