Either the
Winegard 6000 or the
Antennacraft FM6 should work well for you if the desired weaker stations are in the same direction. I have personally used the Antennacraft & was very pleased with it's performance with stations up to 80 miles away.
If your desired stations are in various directions, the
Antennacraft FMSS or
Winegard 6010 may be a better choice. Either of these omni antennas should provide better performance then the 4228.
Mount the 2 antennas at least 4 feet apart if possible to eliminate any possible interaction between them.
