Designed for demanding airborne applications such as telemetry, data link, and transponder systems, this rugged and ultra-lightweight antenna is built to withstand extreme vibration and shock. Operating at 2.2–2.4 GHz (frequency can be revised), it provides 3.22 dBi gain, linear vertical polarization, and a 360° azimuth × 73.1° elevation beamwidth. With >36 dB cross-polarization isolation, a 1.7:1 VSWR, and a 30 W power rating, the antenna offers reliable and robust performance in challenging airborne environments. It is equipped with an SMA female connector for easy integration into various systems.
