| Can rg6 cable carry high speed internet and directv at the same time? I'm moving into a new home next month that is prewired with rg6 cable. I want to get high speed internet from our local cable company, but I want to have my tv service provided by directv, dish or voom. Can all this stuff go over the same rg6 line? In our last home, when they installed Dish network they had lots of ugly cables hanging out the wall. I want to avoid that. If I can't go it, I'll go with the cable company for everything. Thanks in advance and sorry for the long post. |

RG6 is the cable of choice, in fact, for cable or satellite. However, you will need seperate cables for the satellite and for the cable modem; they can't share the same cable. I do exactly that here: I have a cable modem but get my TV from Dish Network. I'd use the RG6 already installed for satellite TV and just run one additional seperate cable straight to the cable modem. It'll be neat and clean that way.

They should be able to share the same cable if you had an appropiate diplexer to make the connections to the different devices.
That being said, much cheaper to use seperate cables! |

| YA!!! I agree with mogur and xstatic that you should use a seperate cable. RG6 is the way to if using a cable modem. |

Thanks to everyone for al l the info. Based on the info, I'll have them hook the cable modem with a seperate cable and run directv thru the rg6.
Just out curiosity how much does a diplexer cost and how many would I need (one per device)? |

There are also multi-diplexers so you don't need individual ones for each room.
Single units run about 15-20 bucks, multis about 30 and up.
The only ones I am familiar with combine TV RF signals with digital SAT or cable signals. I do not know if there are specific ones for combining digital data (internet) with digital TV signals. It would seem there would have to be....
I would double up on the cables, myself. |

I've never seen diplexers that combine (and then separate on the other end) signals from tv and cable internet access. Does anyone know if such a thing exists? Just curious.
That being said I agree with all here. My house was prewired with rg6 to all rooms too. I have DirecTV and use a cable modem for internet access. Just put the main computer near a jack that won't be used for tv/satellite and use that line for the cable modem. I do use a diplexer for TV to combine my OTA and satellite signals coming into the house and then to separate them at the TV(s) as we don't have locals available via satellite where I'm at. :( The diplexer for this application works like a champ though. :) |

Some, like the Dish receivers do the 'diplexing' within the Sat receiver. They have an analog antenna input port for local channels, if you do not receive locals on satellite. Not sure about cable receivers, but should be able to do so also. But obviously 2 separate cables would be run to the viewing area.
Again, I am not considering high speed cable internet which is a digital signal. |

Thats interesting. The DTV tuners do not incorporate the diplexer in the receiver. For example, my receiver has four "in" ports. Two for each of the two satellite tuners and two for over the air antennas.
I only have one over the air antenna, so my receiver only utilizes three of the ports, each with its own inbound cable. |

A thousand apologies, it can not be a diplexer. It simply routes the analog antenna signal. When you press TV/VIDEO on the remote it routes the output to TV (through a different cable, and you would tune with the TV not the SAT rcvr.)
I never used it, but can see it offers some convenience, but you could just as easily do the input switching at the TV for the separate signals, if you chose. |

| Actually I believe that, at least with my set up, the antenna pulls in a digital signal which runs through the DVR just the same as the satellite signal. That way, I am able to record programing that is garnered from the antenna. |

You mean HiDef? From a regular antenna you can receive standard (non-digitized) TV broadcast, but also HD if close enough and it's being broadcast and the PVR or receiver is HD. |

That exactly right. Its Hi def. |

..to weigh in here, I have DirecTV & Adelphia cable both incoming to our home. I have a Multi-plexer that mixes the satellite siginals (2 diff. ones) & the input of the cable going into it. Output goes to 5 different outlets in the house. I use a Di-plexier at 2 different places for the sat. sig. to go into the sat box, & the other feed out for the cable input into the system. I think the cable installed in the house was RG-60 (?)
There is a seperate cable used for the cable modem setup. It also has a special filter near the multi-plexier JUST FOR THAT FEED! I set that up over 5 years ago. I would think there should a di-plexier by now to split dig. tv sig. & cable sig.? But as everyone else has said, it prob. be just as easy to run a seperate cale for the cable modem!
PS. If anyone's interested, I'll try to get the name & model number's for the parts mentioned! |

Don't forget that digital cable and cable based broadband, although digital, are still carried using the6 MHz wide Radio Frequency (RF) channels that are used on the cable system for standard broadcast channels. You can use 20 year old analog equipment to split, amplify, diplex, etc.
The difficult part comes in the need to be bidirectional. Most amplifies are not bidirectional so passing a cable broadband signal through a one way amp would render it useless, also digital receivers would not be able to answer back which may result in you losing the authorization to decode digital channels.
The DTV downlink signal from the LNB does not use these frequencies though. It is a high frequency 1-2Ghz signal with DC components to switch the LNB polarity. |

Excellent point! Uploading...the big difference. |

I actually have the exact setup you are describing for the new home I purchased. I have DirecTV and Cox Cable high speed internet. It sounds like you're purchasing a built home so pre-wiring is not an option. Few things to keep in mind.
1. If you decide to get Digital Video Recorder (i.e. Tivo) along with the satellite service, you'll need two RG6 connection to the box (one to record, one to watch at the same time).
2. You'll need a separate RG6 line for the high speed internet to the central location where you can hook up the cable modem then to a router if you plan to hook up more than one computer in the house. You'll either then have to hard wire cat5e cable from router to each computer location (difficult and expensive) or go to the wireless (easier and cheaper). If one computer, direct the RG6 line to the computer location where there's the cable modem.
I had my house prewired with two cat 5e lines and two RG6 lines for each location (one cat 5e for phone, one cat5e for internet, and two RG6 for satellite).
