Your #1 ViewSat Source
The Cadillac of Diplexers. Allows you to combine satellite and terrestrial signals into one output, or splits the combined signal from one input into 2 outputs, especially into satellite and terrestrial signals. The satellite input/output is going through for 22 kHz and DiSEqC signals.

In this case, one diplexer joins the two signals together. Another diplexer then separates the signals to the receiver of the TV set and the IRD of the DBS set-top box. More complex systems have a distribution amplifier, which allows each IRD to access multiple LNBs with different antenna polarizations. These usually have an antenna input and a diplexer, so that the antenna signal is also distributed along with the satellite.
Diplexers are also commonly used to combine UHF TV and VHF TV and FM signals onto one down lead, which can then be split back into its component parts as required.
