Welcome to the home of RDF Antennas. We are your premier source for Radio Direction Finding Antennas!

We serve the Search and Rescue community as well as Amateur Radio enthusiasts who use direction finding skills as a tool to save lives and as a hobby.

We manufacture and sell a fold-up 3-element beam designed for radio direction finding Emergency Locator Transmitters (ELTs) on 121.5 MHz or for FCC Amateur Radio T-Hunt hobbyists on frequency of 146.565 MHz.

These antennas are compatible with a wide variety of receivers including the MK4 Sniffer, which we are pleased to offer for sale.
