Antenns have never been rated as power input to the exciter or amp. That would be pointless. What if the exciter was class ab versus a class C CW transmitter? Two different power oitpits for the same power input. Also what about feedline losses? I think some of you are confusing the old way trsnsmitters and amps wete rated in DC input powet versus RF output power. This was never applied to things like antennas or tuners etc. The big thing to remember is that today things are rated in pep power not average power.Cut that rating in half to be safe.
