I thought about that, but I seen some of these attached to Dish Masts with the Dish still on them pointing in all kinds of crazy angles with good reception. I can give it a try, though. I wonder if any of the tower guides would have recommended elevationsI wonder if lowering the elevation of the dish would help. Remember, the dish is designed to aim upward into outer space. People using the hack to get a dish to increase wi-fi signal, for example, have to aim the dish so that it looks like it is pointed toward the ground, in order to get it actually aimed outward toward the signal. Of course, that would probably also mean modifying the antenna mount to raise its elevation, so that the antenna itself would not be pointed toward the ground.
As an interesting side note, I always seem to get better OTA signal strength on Sundays, especially during the fall. I just thought of that this morning while I was re-scanning my OTA locals. I can't prove it, but I suspect that OTA stations are allowed to broadcast at a slightly higher strength on Sundays, in order to ensure that as many people as possible can watch NFL games OTA. Of course, the timing could also be just a coincidence with the weather patterns and atmospheric conditions in my area. I am just relaying my experience and pointing out my observations.
