A small loop like the one you built is a classic H field sniffer I have
used to look for RFI problems in switching power supplies. You could
also build a short E field sniffer antenna by extending the center
conductor of the coax a few inches (about 3 inches would be good). Use
shrink sleeve over a heavy gauge wire would make a good E probe.

A friend sent me a link to a very interesting pdf,
www.conformity.com/0211field.pdf .
The part about using the tracking signal generator and a directional
coupler to find unexpected resonances was very useful.
