I have a diplexer mixing my cable and satellite signals outside the house and another diplexer separating he signals inside. Worls fine.

Now I need to add to the mix the signal from my OTA Antenna (for HDTV ATSC reception).

Is there such a thing as a "triplexer" ?

Can anybody think of a way to mix the signals? (No more holes in the walls, no more cables allowed in my house)


Thanks!

Nope, the cable and OTA signals use the same frequencies, you need a new cable for the antenna...

Satellite is at a much higher frequency range so it can be mixed with one of the others fine. But OTA (VHF/UHF) is the exact same frequency range as cable TV - so you can't mix those it would cause terrible interference. I get such interference just from small signal leakage from a strong local UHF channel 15 - it causes herringbones on cable channels 65-66 which is at the same frequency as OTA channel 15.
