<< You would still have to run a wire from the gate over to your TV, which would likely be as much of a pain as installing a moderately sized house-mounted antenna. >>
The TV is right beside the doors, which are inches away from the gate.

I had cable and I didn't really see much benefit for the shows I watch, and the quality was actually lower than OTA (since I live close to the transmission tower). DSS is problematic since the TV is on the 2nd floor and the roof is the 4th floor, and I can't have long runs of cable outside the building (condo/townhouse).
