If moisture has entered the coax you can get some rather unpredictable results... Some channels affected more than others.

I'd start by checking for signs of moisture or corrosion at the antenna, particularly at the coax to antenna connection.

If no obvious moisture or corrosion are present, run a new piece of coax from the antenna to a single TV, keeping the run as short as practical (50' or less) If you can verify good signal from the antenna, then move on to trouble shooting cable and splitters that are not out in the weather.

Also, consider the possibility that some stations may be running on temporary antennas or transmitters if they are transitioning to a new channel due to the repack. If you post a link to your TV Fool Reception report we can help investigate that possibility.
