LNB Switchplate Assembly

Redundant LNB systems minimize system downtime due to LNB failure by providing a spare LNB and an automatic means of switching to the spare upon failure of a primary LNB. A 1:1 system provides one spare LNB for one primary LNB. A 1:2 system provides a spare LNB for either of two primary LNBs. The systems consist of an outdoor plate assembly which mounts at the antenna hub, an indoor control panel and interconnecting control cable.
