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.
73,
Al, W8UT

(did the meter get there yet?)
