Alan It depends on what sort of power level you're looking at - and how accurate you need the results to be. I've used a simple "crystal radio" approach. An Antenna feeds a schotty diode feeding an old analogue meter movement. A couple of rf chokes to allow the return current and you're done. The antenna can be arbitrary length or tuned to the frequency of interest. You can add tuned circuits for the band of interest if required. This was for ~15watt R/Ts in the 100MHz area. Test against known good sets and you pretty soon get a feel for whats a normal response and what isn't. Or you can see if you can light up a florescent tube from the tip of the transmit aerial.
