New generation DBS systems view and receive signals from satellites in multiple orbital locations to provide HDTV programming and local-to-local television programming. These multi-switches take the signals from two dual LNBs and the signal from an off-air antenna or cable television and distribute to four satellite receivers. Satellite and off-air signals are separated at the DSS receiver using a diplexer. This multi-switch is weatherproof so you may mount it outdoors.
