The frequencies are from 2 to 3 MHZ (more MF than HF, so it is 'short'). I can measure the power out of the transceiver, but not out of the coupler. Plan is to measure the transmitted power at approximately 1 km with a calibrated antenna ("known gain").
Also, after tuning to a test...
I am trying to determine the system gain (gain from the output of the transceiver to the output of the antenna) of an existing antenna system used for both transmitting and receiving. The antenna has a tunable coupler between the transceiver and antenna. What is the best procedure? I also need...
