I don't know what your intended use is, but if you just want to measure
output power while testing a transmitter, what about just measuring the
voltage across your dummy load, since, for the same resistor, power is
proportional to voltage squared? (It may take a bit of work/ingenuity
to measure RF voltage at six meters, but that's one of the things that
being a ham is all about.)
