Chelton has a complete suite of Direction Finding Antenna Systems to maximise rescue success

Chelton's 935 and 938 Series of Direction Finders (DF) provide a range of integrated DF solutions for bus-controlled and stand-alone direction finding systems.

Our Direction Finders include five Guard Receivers to monitor pre-defined distress frequencies and an additional tuneable receiver, which can be used for frequencies from 30MHz to 470MHz (935 series) or 88MHz to 470MHz (938 series).

The receivers operate in parallel such that if the tuneable receiver is dedicated to a custom Electronic Tracking System (ETS) frequency, the other receivers continue to monitor the international SAR frequencies in parallel, as well as provide decoded information in the case of Marine DSC and COSPAS/SARSAT.
