If 1kW 'forward' results in 10W coming out of the 'forward' line, doesn't 10W
also end up in the terminating resistor on the 'reverse' line?
The coupling spec. is 20dB nominal from 100MHz upwards - I'm guessing it's
lower (more dBs) 1.5-30MHz, which might account for the termination surviving
if my view is valid.
