Hi J,
I've done it with a suitable scope probe, with the 100mw going into a 50
ohm load. I think your way would give you an indication, I've done the same
sort of thing, using the meter for an RF indicator, with a bit of an antenna
on it (for VHF stuff at least). You might couple your setup to the 100mw
signal thru a .01 cap, maybe, just for safety.

Al, W8UT
(did the meter get there yet?)
