Can I use one cable in a 15' component cable for the 2nd coax to a Dish rcvr?

[wsdickerson]

The Dish installer tried to upgrade our Dish service with two 722k (with OTA modules) DVRs yesterday but hit a snag that one of the rooms only has one coax cable. There is an unused 15' component video cable from the room where the other 722k will go. Could one of the cables in the component video cable be used to supply the OTA antenna signal to the room which only has one coax?

I think the TV2 signal would have to use the same coax.

Thanks

I can't think of any reason it wouldn't work, since component video cables are 75-ohm nominal (or, at least you can use 75-ohm coax for component video). You would need an adaptor at each end ("F" male x RCA female). These are available at Parts-Express.com and other places. It's sure worth a try if it's very difficult to run coax to the other room.

Component

Are you sure it is component? Is it marked as red, green, & blue or yellow, red & white?

 

[wsdickerson]

The cable I installed was: 15FT 5-RCA Component Video/Audio Coaxial Cable (RG-59/U). I picked up two RCA female to F-connector adapters and now have 43% Dish signal (acquired OK) using the blue component cable.

Thanks for the replies.

You only need one RG-6 cable from the dish if you have a DPP switch in the LNB or after it. If you are using a DP-33 or the like, THEY should have changed the built-in switch or sprung for a DPP-44 switch.

While 15 foot may not be impossible, the loss of high frequencies for a tuner is appreciable. If it were OTA (<900 MHz) I'd go for it. What was the component cable doing and can't you route an RG-6 cable alongside it. So if you were using an RG-6 for OTA, it should be simple to switch to Dish signal on that one. Then you could use whatever works on the OTA including twin lead and a bal-un or approximately 75-ohm, even 50-ohm cable. Or use diplexors to send OTA and satellite thru 1 RG-6 cable. Try to have as few mis-matches as possible. A diplexor is a minimal mismatch if correctly done but must have a DC pass to power the dish or switch from the receiver or power supply.

The critical one is the Dish signal to 2GHz on DP (two cables) or 3GHz on DPP (one cable and a separator).

The installers will insist on "blue" core feed-thru or couplings for the Dish signal, white core can mis-match.

The installer stopped before changing the dish (he didn't have the receivers we decided to get instead) and I told him he could leave everything until the next visit. Today we decided to go with our original order (two 722k's) even if only one can use the OTA module. The installer said the room with one coax would be OK for the 722k but not with the OTA module. Today was a test to see if we might be able to use part of the component cable to allow using both OTA modules.

Both rooms are finished now so I can't run another RG-6. I should have installed conduit but I pulled an HDMI, two CAT5's and the component with audio.

The next visit is scheduled for Sat afternoon so I'll be working on OTA Sat morning. I'll ask what switch is being installed. These responses should help me ask the right questions.

Thanks

Diplex the OTA into the sat cable and then split it out with another diplexer inside to a splitter to go to both rooms.

I agree with watchel1. Just diplex the OTA signal onto the sat cable to the receiver. I'm surprised the installer didn't suggest that in the first place.

The upgrade was rescheduled for tomorrow. The dish is supposed to be a 1000.2. I think what we need is very similar to distribution example 11 (I will try to attach) except ANT IN to receiver B will split and feed through the 15' RG-59 to ANT IN on receiver A.

Do the installers carry the Super Home Node or will I have to order one and install later?

The 1000.2 dish will not require the DP Plus 44 switch?

There will be two SAT cables and one OTA cable from the attic to the panel in the basement (we have three plus one I would have to check)? The Super Home Node would go in the distribution panel. Other rooms where we might want OTA or TV2 have coax runs to the panel.

I won't need the component cable for any other purpose - I can use the HDMI to swap TV1 from one room to the other temporarily.
