Depends--, if in phase, Both INPUT, and OUTPUT,
would add (double power, if SAME power on both,
Also would add, if 180 degrees OUT of Phase, both
Input, and Output. And this would be the same as
with Push-Pull amp (both input, and output). but
if In Phase, on input, and OUT of Phase, on
Output,or vice versa, theoretically, would result
in 0 Output. And, if in different phases, probably
would make a great interference source!!!

Just cusrious...

What happens if you pipe the output of one radio in to 2 different
amplifiers, and then take the output of the two amps and send them to
two identical vertical antennas spaced a half wave apart and with
equal length feedlines from the amplifiers.

Will the output of the two amplifiers add together in directions where
the signal is in phase, or will it act like two different signals and
interfere with each other?
