Unlike some other directional antennas like a Yagi, the loop antenna is used in the null mode (minimum signal) because the null mode can provide a very sharp bearing, readable to plus or minus five degrees. The Loop Antenna has the advantage of being less affected by reflection signals due to its Faraday shield. By itself, the loop can provide the entire antenna requirement for direction finding provided the signal is strong enough to be received by the untuned loop. If the signal is too weak, a Yagi is recommended for its directional gain. If the signal is too strong, the use of an attenuator may be required (Offset Fox Hunt Attenuator). Radio Direction Finding is an art, not a science. It requires skill. You may need to practice to acquire that skill.

broadbanded VHF receive antenna
Works pretty well. I've tested it with different transmitters across the VHF spectrum, from broadcast to air band to 2 meter amateur. Produces a nice deep null that is easy to see on an S-meter. Would be nice if the connector were a little tighter so that it will hold a position better, but a few rubber grommets fixed that. Somewhat expensive but well built and I don't think they sell in the millions of units so there's no economy of scale.
