Transponder antenna for experimental aircraft. This product is similar to Comant AV-22 or CI-101, but is non TSO’d.
Fed by a 50 ohm coaxial transmission line (RG-400), the antenna offers a voltage standing wave ratio of 1.2:1 at 1090 MHz and less than 2:1 at 1030 MHz. The antenna presents an omni-directional vertically-polarized radiation pattern when mounted to the underside of the aircraft fuselage. It is readily mounted using an “O-ring,” sealed single hole bulkhead-feed-through with a BNC type female connector.
Frequency: 1030-1090 MHz
We also offer a blade (fin) style transponder / ADS-B antenna. See CI-105
