Comant’s four through hole rectangle style mount (ARINC 743A footprint) Iridium antenna with TNC port and GPS non WAAS with BNC port.

Iridium C159d certified primary designed for airborne bi-directional NGSS (Next Generation Satellite Systems) communication/data function between aircraft and the Iridium satellite constellation.

A secondary non-flight critical function of the antenna is to provide a non-navigational GPS feature. It receives data from the GNSS (Global Navigation Satellite System) constellation to report the geographical location of aircraft around the globe.

Suitable for top mounting for both light and heavy fixed wing single engine / multi-engine, helicopter and business jet aircraft.
