I'm using a Clearstream C2 antenna at my location
http://www.tvfool.com/?option=com_wr...9fbe6e4e3935ae. The main stations here ABC, NBC and CBS are on channels 4.1, 5.1 and 7.1. All three broadcast from the same hilltop location in Seattle with roughly the same power, etc. Trouble is I get 5.1 and 7.1 just fine, but 4.1 (ABC) is much weaker (60% signal strength vs 94%) and drops out constantly. What could be the problem? Ive tried a different antenna with much the same result. Thanks.
