This satellite multiswitch module is designed for quick, easy, snap-in installation into our structured wiring panels. Split the LNB signal of circular-polarized small-dish satellite systems for viewing on up to four separate IRDs. Multiplex an antenna feed for local digital and high definition programming and combine the feed from a dual LNB digital satellite dish for distribution throughout your house.Antenna or cable TV input is combined with satellite signal on one cable. Simply connect a diplexer at the receiver end to separate the two signals. No additional power is necessary since the multiswitch draws its operating power directly from the digital satellite receiver.
