What is the effective radiated power (ERP) of a repeater station with 150 watts transmitter power output, 2 dB feed line loss, 2.2 dB duplexer loss, and 7 dBd antenna gain?
The key fact is 286 watts. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
Memory hook: A repeater receives on one frequency and transmits on another.
P = E × I
