Coax cable question

[captexas]

I'm looking at running some new coax cable for tv connections along with Cat5 to set up a network in my house someday. I've seen regular RG-6 and Quad Shielded RG-6 cable and don't know what the real difference in performance is between them. Do I really need to spend the extra $$$ for Quad Shielded just for satellite tv? Also, are the compression connectors better than the old crimp connectors?

I don't think that the quad-shielding is going to help all that much. How much interference could their possible be? If you have a good picture with your old cable then I would not spend the extra cash for quad shielding. Also I think the compression connectors are just ask good because the satellite signal is supposed to be digital right? As long as the signal gets passed along I would go with the cheapest option.

Chris,

Standard RG-6 will work just fine. Quad shield is going to cost more plus you have to use Quad connectors. I have done many hook-ups using Standard RG-6. In fact, in some instances, I have used the exisiting RG-59, which is not near as good as RG-6, and it worked just fine.
As for digital signal on coax, it has to do with bandwidth. RG-6 will carry a larger bandwith than RG-59.
Quad shield, will reject more interference than RG-6.
The newer style compression connectors are weather proof also. You need a special tool for them.
And they cost more. I can get standard connectors for about 20 cents each. Now you can also get moisture resistant and weather proof. 1 style has just an "O" ring in the end and the other has the "O" ring and is flooded with silicone.
As to JC's answer, Better cable better performance. Cable WILL and does go bad, and you may get signal thru it, but it can be bad. If cable sits in water for a period of time, the water will get into the cable and the shielding will corrode and break the ground. Also, little critters do a fine job of eating it sometimes.
Is any of this cable getting buried? If so, you need to get direct bury cable. It is flooded with silicone, and it is nasty stuff!
If you have any questions, just ask.

Well I got the regular RG6 and the compression connectors with the compression tool ($20 at Lowe's). It's an older house and some of the coax is running next to AC lines so it will have to do. I'm sure it will be better than the old RG59 that is in the house now.

Hey Roy - Do you have any extra dual RG6 wire? I'll need to run a new dual line from the satellite to the room where I'm going to set up the hub. I should be able to reroute the other two lines to reach the room.
