About 15 years ago I ran the video install for the CNN studios in Rockefeller Center for Connie Chung and Paula Zahn.

We did the whole 9 yards - Electrical, Telephone, Data, Audio, Video.

Every desk got a telephone jack (Cat 5E), a data jac (Cat 6A) and a Video jack (RG-6).

We ran RG-6 to every desk, but the feeders to the Video amps were RG-11.

There was no problem working with the RG-11. A little stiffer. A different connector.

It all worked well and came out beautifully.

When I did Microwave we used RG-8. That was different. Much bigger. But still Coax.

After running the coax at the church, I did a check on PPC. Was surprised to see that the company is owned by Belden.

I asked the owner of the electronics store that I've done business with for decades if he could order a spool of the RG6 so I could use it at home.

He led me to his office and accessed the Belden website where he orders product. The PPC numbers were not recognized by the system.

I suppose Belden is treating PPC as a completely separate entity and limiting availability to industry as opposed to consumers (I don't think that Graybar or Anixter sell it). Wouldn't surprise me if the cable for both brands is produced in the same factories on the same equipment.

Perfect Flex is tri-shielded while Belden 1189A is quad. Belden 1613R is tri, but, the retailer doesn't stock it, so, he special ordered a box for me. He doesn't carry the Belden compression connectors, but, Lowes does. smile

Belden also bought West Penn, a company that makes cables for the audio industry. If you don't like the competition, buy them out.

We use PPC connectors here. We keep it the same as the cable company although they always cut them off and install new ones even if their own guys put them on.

It is not hard to work with, but you obviously need the larger compression connectors. Those connectors may take a little more time to push on to the cable

I have read that RG11, because of its thicker design, has a larger bend radius than RG6, thus making it unsuitable for residential use. Spec sheets do confirm the larger bend radius.

For loss calculations, I suspect that couplers would attenuate. I have (4) 90 degree bends installed (cable management) as well as a coupler (baseboard jack). Whatever the amount of loss added in, all three Arris boxes are functioning properly. smile

Ugggh! Stop reading that internet garbage! Unsuitable for residential use? Why, do you live in a tiny house? All cable has a minimum bend radius including 6 size cable.

Couplers? You mean F-81 barrel connectors like on wall plates? Yes they do have a loss but it's so minimal that it's not an issue.

What I have no use for are those 90 deg connectors. I believe the loss is more than a barrel, dunno. I just never liked them, maybe because a length of cable is so much cheaper.

Nope...looking at manufacturer documentation.

Belden 1189A: Minimum Bend Radius - 2.9"
Belden 1523A: Minimum Bend Radius - 3.9"

While 3.9" is far better than Hardline cable's bend radius, it can be cumbersome to run in tight/confined areas.

I can't imagine where you would be trying to stuff it into that that would be a problem. If it is, it just might be that an 11 size cable shouldn't be used or you need to make allowances for it.

If i were to do anything with 11, it would be between the ONT and the first splitter. However, with attenuation calculations for all branches not exceeding -10db, the need isn't there at this time. When Verizon replaces the existing Tellabs ONT with an Alcatel-Lucent, I'll revisit. smile

Here is a picture of the Tellabs ONT in the basement.

Shouldn't make any difference,the output level should be the same. The carriers are generated by the ONT and I wouldn't be surprised if they were adjustable. You would just have to get a Verizon tech who knows what you are talking about.

If you are really serious about this save up your lunch money and get something like this:

It's a nice installer's meter.
