Quad shielded cable can be used in OTA applications with no gain or loss in performance in the majority of cases. Because the antenna end of the coax is intentionally 'open' to the air, most installations will not see any improvement in signal to noise or reduction of interference if extra coax shielding is used.
The added cost is worth it in applications such as satellite reception because the connection between the low noise block converter on the dish and the receiver uses frequencies that are also in use in terrestrial microwave systems. The added shielding keeps the two applications from interfering with one another.
Bottom line: For OTA applications, if the quad shield is the same cost or less, use it. Otherwise dual shield RG-6 is fine.
