Toyon has developed a unique multifunctional antenna for airborne telemetry transmitters. For example, Toyon’s tri-band, GPS interference-reducing telemetry antenna (image right) provides transmit capability at lower L-band, upper L-band, and S-band telemetry frequencies simultaneously. The transmit pattern at lower L-band also features a pattern null that can be pointed in the direction of vulnerable GPS receivers to reduce interference caused by telemetry signals. The antenna is flight-ready, and has been certified by an independent testing lab for operation at airspeeds up to Mach 2.0, at an altitude of 5000 feet. This flight-ready, tri-band aircraft telemetry antenna features a transmit pattern with a null to reduce interference to nearby GPS receivers.
