The manuel says rated at 250 watts transmitter input power, so I would
guess that would mean about 200 watts output. I've run 500 watts output
into the set I am using and had no heating or arcing. Remember, when
they rated something years ago, they were usually very conservative and
these are open air coils - there is no core.

Ratio can be set for 1:1 or 4:1 by minor rewiring. I've always run them
at 4:1 and fed ladder line.

Input is a PL259, output is two ceramic feed through terminals with nuts.

I have two of the units and wouldn't give them up for anything.
