We can have 67% reflected power and still have nearly 100% of transmitter power getting into the antenna and being radiated.
Then could someone please explain why the manufacturers of ham, broadcast AM/FM/TV, and other transmitters specify the maximum SWR (e.g., minimum return loss) for the loads they may drive at full, rated output power (no foldback)?
If "nearly 100%" of the r-f power output of such transmitters was radiated by the antenna system regardless its VSWR/return loss, what would be the need for such OEMs to specify a maximum load SWR?
