WebThe higher power station would have to run at about 600 watts out of his transmitter assuming the same 10:1 swr to get about 1 S unit higher reading over the lower power station. So the bottom line here is that the higher the swr ratio is to (1), the less output to the antenna system due to transmitter power reduction.
