I'm a little over 100 miles from a few transmitters, done all the charts on tvfool.com and I know that I need something that can receive just about the impossible. What is considered the best? I know the Channel Master 4228 and Antennas Direct 91XG are highly recommneded. Is there anything else I should consider? I'll probably buy 2 and return 1 but I want to make sure i buy the best 2. Thank you for the help.
