CI 273
CI 273
Designed for single engine piston aircraft, this antenna is suitable for various applications. It is recommended to consult with an FBO or installation shop for optimal application information.
The antenna operates within the frequency range of 403-512 MHz, with specific performance specifications across different band segments.
This model is similar to the CI 271 but is specified for the 403-512 MHz range. It is a stub antenna designed to endure harsh environments typically found on the underside of aircraft. The antenna radiator is mechanically secured and sealed to prevent leakage, and all exposed metal surfaces are nickel-plated for corrosion resistance and durability. It mounts through a single 0.60” hole and uses a standard BNC connector.
