Arrow Fox Hunting Loop - Bidirectional Antenna for Radio Direction Finding

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 to received by the untuned loop. If the singal 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.
