With the DPP Triplexer you can use a single cable to supply signal to both inputs on a dual tuner receiver
When used with a diplexer on the other end of the cable the triplexer allows a single cable to carry both a satellite signal and a tv signal from either an OTA antenna or the home distribution port on your dual tuner receiver
The DP Plus Triplexer combines the functionality of a DISH Pro Plus Separator and a diplexer into a single device to simplify installation.
