Multiband Tuneable Blade Antenna – 12-5002

The 12-5002 Antenna is a Multiband Tuneable Antenna designed to provide communications over the frequency band 29.7 MHz to 960 MHz and intended for operation in general subsonic airborne applications. The antenna comprises three separate radiating elements: The VHF function from 29.7 MHz to 174 MHz is fulfilled by a tuneable structure wherein a network of inductive elements are switched in combination by PIN diode switches to tune the antenna to the frequency selected by the radio. The tuning information is provided by the appropriate logic control unit. The UHF function 225 MHz to 400 MHz is fulfilled by a passive element. The feed to this is combined with the VHF function via a simple L-C network to allow connection via a single RF connector. A separate radiating structure provides the 400 MHz to 960 MHz capability via a second RF connector. The antenna system is a replacement for Antenna Type 12-190-9 and Logic Converter Unit Type 7-19PIN9 providing improved harmonic performance.
