Radio Direction Finding (RDF), often called fox hunting, is a popular amateur radio activity where operators use specialized equipment to locate hidden transmitters. This skill is not only a fun challenge for hams but also crucial for emergency services and search and rescue operations to find downed aircraft beacons or lost persons. RDF involves using directional antennas and receivers to pinpoint the source of a radio signal, testing operators' technical skills and their ability to navigate diverse terrain.

This category features manufacturers offering a range of gear for RDF, from complete systems to individual components. Hams can find specialized receivers like the VHF Sniffer MK4 for two-meter fox hunts, and various directional antennas, including Yagis and Cubical Quads from companies like CUBEX and ROLCON RF Systems. There are also products like the K0OV HANDI-Finder and Fox Hunting V7 Kits for those interested in building their own RDF equipment or enhancing their existing transceivers for transmitter hunting.
