Quad Shielding won't hurt... but don't pay any extra over the price of RG-6/U (double shielded). The extra shield of quad is needed in closed systems such as the link between a satellite dish and tuner. An over the air antenna is open to the air... the tiny amount of interference that might get through the shielding of standard coax is going to find a much easier and open path through the antenna. The loss is the same for both types of coax... except at DC and 60 Hz AC. There are a few rotator and amplifier applications that can benefit from quad... I don't see that as an issue in your case.
