Aircraft Transponder / ADS-B / DME Antennas
Transponder, ADS-B and DME antennas share the same general L-band region, which is why they are grouped together in aircraft antenna catalogs and why many part numbers are used across all three functions. This category lists the blade and rod antennas we stock for transponder, ADS-B and DME service, with connector type, mounting pattern and airspeed rating from the manufacturer data. Whether a given antenna is acceptable for your transponder or ADS-B unit is defined by that equipment's documentation.

Understanding Transponder and ADS-B Antennas
Transponder, DME and ADS-B Out functions all operate in the same broad band, so a single antenna type is often listed for several of these uses. That does not make every antenna interchangeable: the transponder or ADS-B unit specifies acceptable antennas and cable loss limits, and diversity-capable transponders require more than one antenna position.
Where an ADS-B installation uses a separate UAT or receiver unit, follow that equipment's installation manual for the antenna and coax it requires. Product pages here list what the antenna is, not what a specific avionics unit approves.
Mounting Position and Cable Loss
These antennas are usually belly-mounted and depend on the airframe skin as a ground plane. Position, spacing from other antennas and cable routing are installation decisions governed by the approved data for the aircraft and the equipment manufacturer's instructions.
Because cable loss at L-band is significant, the coax type and run length specified by the transponder or ADS-B manufacturer should be confirmed before ordering an antenna with a particular connector.
