<strong>11</strong> M C-/KU-BAND ANTENNARECEIVE ONLYTECHNICAL SPECIFICATIONSThe Turning Head Antennas, designed and built by VertexAntennentechnik (VA), offer continuous travel ranges, highpointing/tracking accuracies, and allow for operation with allvisible GEO satellites.Single <strong>band</strong> Tx/Rx, Multi<strong>band</strong> Tx/Rx and Multi<strong>band</strong> <strong>receive</strong><strong>only</strong> feed systems are available for nearly all frequenciesup to Ka-Band. The servo & drive and tracking systemprovides various operating modes; remote control ispossible via serial/LAN interfaces.All <strong>antenna</strong>s can be equipped with electrical reflectorheating systems comprising infrared heating rodsintegrated into the reflector panels; thus the powerconsumption can be reduced by heating sectors <strong>only</strong>.The standard <strong>antenna</strong> tower is a steel st<strong>ru</strong>cture providingspace for drive cabinet and racks for electronics.VA offers all transmit/<strong>receive</strong> electronics for an IF, definedby the customer as well as a customized Monitoring &Control System.Program management, inplant integration, shipping,installation, commissioning, acceptance testing,maintenance, after sales services are substantial activities,qualifying VA as a supplier of turn-key ground stations<strong>antenna</strong>s/<strong>antenna</strong> systems.Baumstr. 50, D-47198 Duisburg Page 1
