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?
