I actually had a great deal of success with an attic antenna in a similar location (30 miles NNE of Atlanta), but not without investing a fair amount of time and money. I am in a slightly better situation from a signal standpoint, but my antenna is the attic of my single story ranch house, pointed directly into a 20' hill behind my house.
For reference, here is my TV signal report for my location:
http://forum.tvfool.com/forumdisplay.php?f=7
Here is the setup I found success with:
- Two antennas
- Channel Master CM-2020
- Winegard YA-1713 (VHF only)
- Two amplifiers
- Channel Master CM7777 Preamplifer (separate UHF/VHF inputs, gain of 23db VHF and 26db UHF)
- Channel Master CM-3414 4-port distribution amplifier
- High quality cable
- Quad shield RG6 throughout
- Custom made cables to be shortest possible length
- Power conditioner
- Installed power outlet in attic on separate circuit
- Added Monster Cable MP-HTS200 2-Outlet Home Theater PowerCenter to minimize electrical noise to amplifiers
I have both antennas mounted on the same mast, along with the preamp. The cable lengths to the preamp are both less than 2', the cable to the preamplifier power inserter is roughly 3', and the cable to the distribution amplifier is less than 6". From there, it is a 15' run to one TV and a 25' run to the other TV.
I found that, in order to receive WXIA (NBC), I actually had to point the VHF antenna several degrees to the right of the compass direction to get the best signal. I assume that this has something to do with the 2 refractions between me and the tower, but YMMV.
Below is a list of the channels I am able to receive with this setup. As you can see, a lot of them are not even listed on the tvfool signal analysis, but they are coming in clear for me!
