Personal opinion here and based on a lot of CATV RF experience (30 yrs)...
I don't "prefer" to use quad shield (foil-braid-foil-braid) coax. It has it's place - certainly, but that place is typically where RF interference is suspected. For the short runs in our homes and RVs, I'd prefer to use a standard dual-shield (foil-braid), where interference at the frequencies we're using is not suspected and where connectors are properly crafted.
In the business, there are different connectors for different construction of coax. Dual shield and quad shield having different connectors. Reason being, the outside diameter (OD) of the cables are different. It's impossible to "properly" craft a standard connector (one made specifically for dual shield) onto quad shield cable.
This all said, for the home gamer like us, RG6/RG6Q connectors are available at retail. That is, a single connector with enough tolerance to fit both standard (dual shield) and quad shield coax. To this however - I cry "foul". Hate those connectors.
I wired my new home with quad shield as that's all I could find at my local Lowes (small town). I bought the Ideal brand of connectors that are supposed to work on dual/quad. Oh man - HARD to install on quad. I dialoged with Ideal directly on this and they came back with a special process for preparing the cable for the connector. In my opinion, it somewhat defeats the purpose of quad shield - to trim it the way they suggest in order to make the connector fit.
To do all over, I'd work harder (order online) to obtain standard dual shield coax.
Okay - off my coax soapbox. I suggest each does his own own research and draw their own conclusions on what coax to use for your application - instead of allowing me to impose my conclusions on them.
