Cost.
Quad shield is appropriate for satellite systems. Satellite systems convert the signal received at the dish to an intermediate frequency range. The link from the LNB at the dish, to the receiver, is a closed system that uses frequencies also in use by terrestrial services. There needs to be a great deal of shielding protection to keep the terrestrial services and satellite system from interfering with one another. A little bit of land based point-to-point microwave signal leaking into a satellite LNB-Receiver link would interfere with reliable reception of the satellite signal.
Over the air reception uses an open system, where the 'opening' is the antenna. The minute amount of signal that may leak through two layers of shielding versus four, is not relevant given that the antenna's object and purpose is to get signal coupled into the coax from the air. Over the air TV uses frequencies assigned exclusively to that service, to minimize interference.
The loss per foot is virtually identical between RG-6 and RG-6Q.
If the price is cheaper for quad... use it.
