7.5 meters Ka-Band - Ground station antenna
BT 750 Ka
The BT 750 Ka is suited for different Ka band applications (Gateway, IOT, TT&C). The shaped Cassegrain antenna and the precision machined subreflector provides high performances in terms of gain and sidelobe. Its self aligning characteristics allows a simple an fast site installation. The reflector back structure and spars are designed to provide suitable rigidity to cope with different environmental conditions. The hub is designed to host several electronics equipment as HPA, LNA, frequency converters. The platform allows easy access to the hub for electronics installation and maintenance.
The rugged steel mount allows for a low pointing accuracy in windy conditions. A precision azimuth wheel with dual DC motor drivers allows for a very low backlash. The proprietary antenna control system supports
both step tracking and monopulse autotracking.
The Motor Drive Unit is located within the pedestal and connected to the indoor Antenna Control Unit by a single high speed link. The antenna could be customized a wide range of configurations and frequency ranges according to the customer needs.
