Belden 7915a, 3Ghz tri-shield...Problem solved.

New Problem: does every supply house carry F connectors for this cable?

Sometimes the solution to the problem is the most common thing, not the best possible thing.
A good answer is easier with a clear question giving the make and model of everything.

Most quad shield ends I have seen, work fine on that cable.

You realize that for satellite, there is DC voltages involved and the voltage drop of SC vs. CCS is substantial. Also for VHF & base-band signals, the loss per ft. is significant between the 2.
I only use SC quad shield because of the overkill. Because I can pull a 250ft run when I need to, without any worries (for any service) - try and do a 250ft pull with CCS dual shield and see if you have problems. Before you answer "I have done it and had no problems" I submit to you that there were problems, you just didn't realize it and/or wasn't using enough service on the cable that would show. Ignorance is bliss.

Like I said however; for the short runs that the OP is doing, he will have no problems with just about anything he puts in. Especially with the Coleman cable.

I am glad you know why you are pulling the cable you use. I was simply providing some info. Many people pull overkill cable because they are so worried about the future what ifs or just assume it is better. Have considered RG-11?

You're totally right. Somehow I got it in my head that the OP was talking about CCTV, not CATV. My comment about "no skin effect" applies to CCTV and satellite, but not CATV.

Something is only overkill, until it is not overkill.

Many installers don't pay attention to the length of runs they do in a home.
I lost a bid to prewire this home - knowing my quality, the builder still choose to go with some fly-by-night company because they were almost 1/2 my cost.
The house was only 4000sqft but kind of long. They put the LV panel at the opposite end of the house (under the stairs) from incoming services. I was going to have it in the equipment room with the home theater, that was on the same side of the home as the services. Made no sense why they did that (really stupid).
They used cheap CCS RG6 and had over 100ft runs thru the house. So from dish, to panel, to receivers thruout the home; some runs were averaging almost 200ft. Once moved in, guess what the DirecTV installer told them when they were having problems installing the system. LOL you can't fix stupid. Even if I had been 1/2 asleep and had put the panel in the same location, I guarantee the DTV installer wouldn't have had problems with my cables at those lengths.


RG-11 is generally to rigid to run in homes. The bend radius is huge. Plus, you would need to be going over 250+ft before it would even need to be a consideration. I have used it to connect mutli-buildings together before.

Sounds as if Direct is really the issue. Safe to say most homes are ccs and Direct should have designed the system to use it. I am with you on better cable regardless. I too have run into house I did not do the prewire and Direct would not work. Nice being able to say it was not my issue!

ICM/DigiCon/Belden compression fittings work perfectly [which is what I use], as do Platinum connectors.
