L1 GPS Antenna

The aero dynamic design ensures excellent Omni directional pattern over the entire 1575.42 MHz band. The AT2300-326 is a combination of GPS antenna and XM satellite receiver antenna allowing you to replace an existing GPS antenna with a dual purpose antenna. The AT2300-326 has a standard ARINC 743 footprint and can be installed on all piston, turboprop, and turbine airframes. The AT2300-326 is optimized for use with WAAS Gamma 3 GPS receivers and is approved under TSO C-190.

Combination GPS, VHF communications and XM satellite receiver antenna is designed for use with WAAS Gamma 3 GPS receivers and is suitable for use on all turbine, turboprop, and piston airframes. The AT135-3 is designed to replace three separate antennas with one antenna, reducing both weight and drag and minimizing the number of penetrations to the airframe. It is designed and approved under TSO C190 and TSO C169a.

The AT575-234 is a high performance GPS antenna with an ARINC 743 footprint which can be installed on all turbine, turboprop, and piston airframes. The AT575-234 is FAA approved under TSO C-190 for use with GPS receivers requiring 29.5 dB gain or more and is specifically designed to be used for all GPS operations up to and including Gamma 3 LPV approaches.
