US Patent 11677436 Antenna optimization for SATCOM waveforms

A platform is provided which removes the need for the pilot to select between high angle and low angle antenna elements. By the automatic selection, the platform may improve BLOS connectivity during various phases of flight, such as during banking operations. The platform includes a SATCOM antenna including first and second elements. The platform also includes one or more SDRs which provide receive and transmit functions for the BLOS waveform. The platform may also include either a UHF diversity combiner or an LNA diplexer assembly. Thus, two methods are described for reducing out-of-service events for CDMA and legacy Narrowband UHF SATCOM.
