Terk Technologies BDS-P1 Indoor/Outdoor Diplexer (Single-LNB)

TERK diplexers combine and separate satellite and off-air broadcast or cable signals with minimal signal loss. Available in 2-models for single-LNB and dual-LNB satellite dish installations, TERK diplexers allow the user to combine the signals from a satellite dish and an off-air antenna or cable TV hookup, eliminating the need to run extra wiring into the home.TERK's diplexers can also be used to separate the signals and route them to satellite receivers and the TV sets antenna inputs. TERK's DC pass feature allows the diplexers to be used with amplified antennas that require DC power via their coax cable connection, unlike most diplexers that will not pass a DC signal.

The title misleads the buyer into thinking this is only good for single-LNB dishes. I purchased the following with my triple-LNB dish, supplied by DirecTv: (08) Terk BDS-P1's, (01) Terk HD-TVS off air HD antenna and the Terk BMS-58 switch to make everything work together. I experienced no problems with the installation. DirecTv receivers see all 3 satellites and have the option to receive free HD TV from local towers. The BMS-58 switch works as a combiner routing all signals through 1 coax cable. This makes running cable cheaper. The diplexer then splits the signals at the DirecTv box. I also use this for TIVO with no issues.
