It protects one receive chain: an online LNB and a hot spare share an outdoor switch plate at the antenna hub, and the indoor controller switches to the spare automatically if the online LNB fails.\u003c\/p\u003e\u003cp\u003eThe plate takes Norsat Ku-band PLL or externally referenced LNBs, ordered separately, on a WR-75 waveguide input, in one of three LO plans: 10.95–11.70 GHz (10.00 GHz LO), 11.70–12.20 GHz (10.75 GHz LO) or 12.25–12.75 GHz (11.30 GHz LO). Options include input isolators, Tx reject filters, crossguide couplers, offline LNB ports, a remote control panel and ±48 VDC power.\u003c\/p\u003e\u003cp\u003eOrder the plate and controller as BRK-1100, choose a band plan, and specify the Norsat Ku-band LNBs separately; Digisat can quote both together.
