I've been satisfied with the standard dual shield product stocked at Home Depot. I've used the factory assembled cables as well as the 100' & 500' rolls of bulk product.

I can't think of many instances where quad-shielding provides any tangible benefit in an OTA antenna application. The primary purpose of quad-shielding is in applications such as satellite LNB to receiver... Where the frequencies overlap with terrestrial microwave systems. Any signal leaking in or out of the cable would pose an interference problem. If the product is priced the same or you want to be able to use the cable in a satellite system at a later date, then certainly use it, it will do fine in an OTA application.

In OTA antenna applications, the antenna end of the coax is effectively open to the air, given that it's intentionally connected to the antenna. A small amount of signal leaking through the shield poses no significant problem.
