I am trying this OTA thing as a cord cutter but I'm having trouble selecting the right antenna. The towers for all of my affiliates are between 15 and 29 miles away. My main problem seems to be the direction of the towers. One is north at 14 degrees, one is east at 91 degrees, one is southeast at 150 degrees, and one is south at 178 degrees. I've tried two antennas, a 70-mile multi-directional antenna and a 125-mile omni-directional antenna mounted outside as high as I can mount them without adding a pole to my yard but I'm having the same problem with both. I can get the south, southeast, and east towers decent on clear days (weak in the rain) but the north tower barely comes in even though its only 19 miles away. Even pointing one of the antennas directly at the north tower, the signal is weak on a clear day and totally out in a light rain. Any suggestions on an antenna? My zip code is 75703 if that matters.
