RG-6 copper center conductor is the best for signal transfer and quad shield adds another layer of shielding. The added layers of shielding is better because standard RG-6 has two shields , the aluminum that is bonded to the foam and the shield wires. If standard coax is streached or bent to many times the foil shield and the shield wires can break , this is not likley to happen with quad shield. As with any coax and connectors , look inside of the connector on the end of the coax and see if the shield and shield wires are pushed in toward the center conductor , if so then push the shield and shield wires away from the center conductor. Also to make the shield part of the coax more effective use a coax grounding block and ground. Can quad shield be used ? Well yes it can.
