I have a customer who wants both hd cable and hd satellite, however there is only one coax at the wall. Can't fish another one. Does anyone know if normal diplexors(channel vision,Spaun,Channel Plus) will pass both hd cable and hd satellite.

I don't think you can even use a diplexer to pass both digital cable and satellite. I believe they use some of the same frequencies. Why can't you get another coax there? There is always a way 99.9% of the time.

do it like the cable and dish companies and drill through the wall from outside.
Mc Nasty is right I rarely see a "no way to do it" wall. Now there are the "no way to do it at low cost" walls which I've seen plenty of. :)

diplexers work, cable and satellite are different frequencies

I know normal cable and HD satellite will work with diplexors, but I'm not sure about HD cable. In reference to retrofiting. The house is worth about 14.7 million and the owner does not want a coax on the outside wall. The flooring is 1 3/4 coral reef. No carpeting shooting!
Thanks, Dean

HD cable uses the same bandwidth as regular cable. The diplexer should work. The best thing to do is try it and see. How long can it take to slap a couple diplexers in?

How hard can this be? |

Try it but make no promises, Diplexers let the signal on the cable travel in one direction. HD boxes need the signal to travel in two directions for PPV and such. If you have a 2 conductor wire or Cat 5 in the room it may be possible to get the cable signal there using an existing Cat 5 with a video balun on each end.

Time Warner cable here in Manhattan has some overlap with DirecTV, as per tech support from both.

deb1919, Which manufacture of diplexors did you use? My clients provider is also Time Warner.

Hate to disagree with you Bruce but the sat side of the diplexer is a DC path and therefore works identically in either direction. Also, most boxes use a phone line for ppv etc. I've heard that some use the same co-ax, but have yet to see it. No phone line? Just use an ac wireless jack, works great. The balun solution also works just fine, requires a transformer for either end of the utp, available from ADI etc. I prefer channel plus diplexers.

DirecTV's frequency range starts at 950mHz, where Time Warner Cable uses up to 1GHz. Using a diplexer should render anything in that 50Hz common range useless. What exactly falls in that range, I'm not sure.

There was no question of the diplexer passing two ways on the SAT side, otherwise it wouldn't be a diplexer. The question was whether or not the CABLE side of a diplexer would let digital cable and PPV signals pass in both directions over the RG-6 as is needed for these boxes to work correctly. especially when using I control. A DC passing two way splitter would probably not be able to keep everything separate. The Time Warner cable boxes in use in our area do not use a phone line
