    Quad Shield or Dual Shield RG6

    I need to run some RG6 for FiOS and I'm being told to run quad shield instead of dual shield. Personally I don't think that it will make any difference and the quad shield is about 40% more expensive. Any opinions?

    There's a cognitive disconnect between FIOS and coax....

    How long a run? Less and a 100' or so, I'd probably run whatever whatever quality 75 ohm coax I had handy (and assuming I have the connectors on-hand). (Don't usually have "RG6", usually have Belden 8281 or 1505.)

      No run is more than 100'. One of the "purists" on the job said the quad shield was worth the extra money but I don't believe it will make any difference.

        The only thing I've heard from a satellite tv installer that does make a difference, is buying the RG6 with the solid copper conductor, versus the copper clad steel or aluminum, or whatever it is.

        I've never followed up on it though, if you can tell, we don't install much coax in our work.

          Do they also buy the $100 oxygen-free cryogenic-enhanced power cables?

          If you're under maybe 500', I'd think that double-shield would be fine. If you have to buy the cable, might as well get that and decent connectors.

          BTW solid copper center vs copper-clad wouldn't make much, if any, difference for the RF signal (skin effect), might if it's carrying LNB power to a dish.

            You know the type well.

              Sounds like the "Audiophiles" that demand gold plated connectors, or "Monster Cable". My experience is as long as it's a decent cable and connectors are terminated properly, it will work fine.

                I always try to use what the cable company, or in this case Verizon uses. Personally I don't think dual vs quad will make a difference either but if Verizon is willing to pay for quad there must be a reason. First, make sure your information comes from Verizon regarding quad being necessary, not someones opinion. Then, if you ask nicely most cable companies will give you a box of their cable and I can't believe Verizon won't do the same. After all, you are doing them a favor by pre-wiring for their service.

                I would let them terminate though unless you want to see them cut your fittings off and replace them with theirs.

                  I added on to my house a couple of years ago. I had to extend a run for my satellite to the new bedroom. I did all the work, including putting the connectors on. The picture was perfect. Later on, I upgraded the Sat. service and the techs had to come in to install the new equipment. When they came to my connectors, they promptly took out their cutters and cut my connectors off and put on theirs!

                    If somebody did that to me, we Have Words (especially as my connectors are probably better quality....).

                      This are new cables for an existing house. Verizon already came and did the reconnect and programmed the TV boxes. They didn't change anything, in fact they left the crimp on F connectors from 20 years ago intact. They didn't even bother to remove the unused cable from the splitter they just left them connected and some of them are abandoned meaning they're cut off on the other end.

                      In the past I have seen them only connect cables that are being used and provided terminating resistors on the unused splitter ports. Tech seemed to be in a hurry.

                        Don't feel bad, they will even cut the connectors off that their last guy installed. And as for using better quality connectors than they use, they are required to use whatever the company issues. But I have to say that I have never seen them use anything but good quality materials. Just because you may have not heard of the manufacturers they use doesn't mean that it's inferior. They don't make any money on repeat service calls.

                          So if they reused some of the existing cable what does that say about using quad or even dual?

                            What matters with shielding is the percentage of coverage. Braid shields vary in coverage from around 40% to the high 90's, but a foil shield covers 100%. Most dual shield cables contain one of each type, and quads are usually two of each.

                            I do not understand any advantage to quad shielding except for manufacturer profit.

                              Wish I read this thread a year ago.
