Height off the ground is the key. I am on Glenview GC by Savannah Center, so about as far north as you can get. I get channel 2 perfectly 100% of the time with my garage attic antenna. But my attic is quite tall so the antenna is 18' above the ground.
The antenna is aimed at about 110° I believe, right at the Orlando transmitter.
Also, the attic has no radiant barrier in the way, as the metal which would kill reception.
I installed a signal amplifier where the antenna cable enters the house. It would have been better to install it at the antenna but I didn't have a 110V outlet in the attic. The cable goes 70' or so before it reaches my TV.
So if you can get another 5' of height by installing the antenna on your roof you will have better reception.
