The 30 m antenna at the DLR site in Weilheim is to be made capable of transmitting in the X-band for future project support. The existing receive capability in the L-band is to be retained. This requires a new combined f…
eed system. The system must be capable of receiving in the L-band plus transmitting and receiving in the X-band. The current feed parameters should not be degraded. The antenna is designed as a near-field Cassegrain system with a total of three reflectors. The following is a simplified representatio
n of the system architecture. The feed system is to be attached inside the elevation cabin to the existing connection points of the elevation swivel coupling. Various solutions (combi-feed, rotating revolver design, switchable, ...) can be
