Comant CI-420-490

Overview

Our low-profile Iridium antenna is Iridium-frequency-only allowing its narrow-band tuning to provide optimum Iridium performance. Why? Other aviation antennas must go “wide-band” to capture the nearby GPS frequency for FAA TSO which reduces efficiency. But we are the first with a specially designed, Iridium-only aviation patch that earned the new FAA TSO C159a for satellite communication. Designed for both fixed wing and rotorcraft airframes, and operating with both Iridium-based voice and data communications devices, the single channel aviation patch provides continuous coverage from 1616.0 MHz to 1626.5 MHz for excellent Iridium operation. Mechanical configuration is our popular aviation “Teardrop” footprint with injection molded radome and aircraft aluminum base plate.
