Lightweight and rugged, the range of HTA-Aerostat antennas have been optimised for airborne use on weight-constrained aerostat platforms. The antennas are also broadband dipole which means that – unlike heavy monopole antennas designed for trucks and aeroplanes – no ground plane is necessary to deliver near-theoretical all-azimuth gain and low VSWR across the band.
These HTA-Aerostat antennas have been deployed in the U.S. Army’s Persistent Threat Detection System (PTDS) and Persistent Ground Surveillance System (PGSS) aerostat platforms.
