AEROSPEC AV-22 (CI-101) Transponder Antenna Stick

AEROSPEC AS-AV-22 Transponder Antenna – Alternative to AV-22 and CI-101

AEROSPEC AS-AV-22 is a rod-style transponder antenna designed for use in general aviation aircraft. It serves as a direct alternative to the AV-22 and CI-101 models and can also be used as an ADS-B antenna. With its robust construction and aerodynamic form, it provides reliable performance at speeds up to 350 mph and altitudes up to 50,000 ft.

The antenna is mounted directly via its BNC connector, ensuring a simple installation process. Metallic components are nickel-plated for corrosion protection, and the compact stub monopole design ensures low drag and long service life in demanding operating environments.
