HITEC-LM-060-Ka 6 meter limited-motion Ka-band Satellite Ground Antenna System High accuracy under adverse environmental conditions for high performance operation in Ka-band frequencies Large working platform and stairs combined with supersized center-hub for housing RF equipment and improved accessibility Standalone system with all antenna components (e.g. power electronics) integrated in its structure Equipped with an Antenna Front Panel, which allows global health and status monitoring, as well as commanding of the auxiliary functions (e.g. HVAC, de-icing) through a single interface Multiple options: • HVAC • De-icing system • Hand-cranking • Logging system • 19'' racks The LM-060-Ka is a low maintenance and future proof antenna system designed for robust, reliable and high performance operation for geostationary Ka-band applications. The LM-060-Ka can accommodate different feed systems and can operate at different frequencies, depending on the application. The reflector, 6.8 m in diameter in a dual shaped Cassegrain configuration for high efficiency, is constructed of precision bonded aluminum panels and can be adapted to diameters from 6.0 to 7.5 m. The backup structure consists of aluminum framework trusses, reinforced by a structural plenum. This configuration ensures optimum rigidity and surface accuracy under self-weight and environmental effects and can accommodate the optional de-icing system. The antenna hub has generous interior dimensions (W x H x D: 1745 mm x 1545 mm x 975 mm) and allows placing up to 29 units of 19" racks (600 mm depth) and installing all converters and high-power amplifiers right next to the feed. Easy access to the equipment is ensured by a large opening covered by roller shutters. The LM-060-Ka is equipped with the HITEC Luxembourg Antenna Control Unit HACU-1000, providing program track functionality as a baseline. Depending on customer requirements and the installed RF equipment, a step-track or monopulse capable version of the HITEC Luxembourg ACU can be installed. Copyright © 2013 HITEC Luxembourg S.A.
