This diplexer from Perfect Vision is a high performance device with outstanding specifications. It separates or combines off-air TV-Antenna/Cable TV and Satellite signals from or onto a single feed coaxial line!!!

You will need one of these at each end of the cable. One to combine the signals on one side and the other split the signal at the other end. They are also used with a multi-switch (combines the signals) to split the signals prior to connecting to the receiver.

2 Amp Passive Used when Dish Pro LNBs and Switches are being used.
