Hiltron Announces HRMU Redundancy and Monitoring Unit for Satellite Communication Antenna Control
First pre-delivery acceptance testing of the new Hiltron Super-HMAM large-capacity motorised antenna mount proved highly successful. Designed for two-way VSAT communication or receive-only downlink applications, Super-HMAM accommodates satellite transmission antennas of up to 4.9 metres diameter compared with the 2.7 metre maximum antenna capacity of the standard HMAM. The first Super-HMAM was produced for a German government civil agency and is equipped with a 4.9 metre antenna. The actual performance achieved during factory acceptance tests in September exceeds the theoretical performance which is very gratifying for everyone involved. Needless to say, the cplete structure is very large and was dismantled before being delivered for onsite installation.
Integral to Super-HMAM is a newly developed support structure which can survive the storm
The Super-HMAM antenna control unit and associated motor-control electronics are contained in an IP65-rated weatherproof outdoor housing with a hinged front-access port secured by dual key screws. An emergency cut-off switch is easily accessible. Above the housing is a resolver which is used to measure the azimuth angle of the antenna. An identical second resolver allows constant monitoring of antenna elevation. Azimuth and elevation drive motors.
