Here is your TVFool.com report:
http://www.tvfool.com/?option=com_wrapp ... 5ce77eab67While Lima has one major TV network, Dayton has all of the major networks available, and should be your primary target. I can't ever recommend mounting an antenna system in the attic because of unpredictable results, but I can tell you that, if you follow my instructions and mount this system on the roof, that you will see all of the Dayton stations plus WLIO from Lima, and you will get them without a hitch.
WLIO operates on digital channel 8, and is fairly close to you, but it is on the opposite direction from all of the Dayton stations, All of the Dayton stations lie in the same direction from you, and are on UHF, so I would recommend a 2-antenna installation for you consisting of the AntennasDirect XG-91 UHF antenna mounted on your roof, aimed at 212 degrees as measured by your compass. I would also use a small VHF high-band VHF yagi like a
Winegard YA-6713 or an AntennaCraft Y-5-7-13 mounted 4' BELOW the UHF antenna, aimed at 325 degrees by your compass. Combine the two antennas using a Channel Master Titan 7777 preamplifier, which has separate VHF and UHF antenna inputs, and be sure to watch the video about the Channel Master Titan 7777 posted on the forum for good installation instructions. I have linked a good general instruction manual below, which will guide you through the installation process: when you are finished, you will see Lima and the Dayton stations without a problem.
