My first recommendations are to work with the antennas that you have to get the maximum amount of Tv stations/channels.
With the Y5-7-13 VHF high band channels 7 thru 13 antenna mounted at the current height of about 23 feet.
Aim the Y5-7-13 VHF high band channels 7 thru 13 antenna at the much weaker WWLP-DT REAL VHF channel 11 , Virtual channel (22.1) , NBC , at about 47 degree magnetic compass.
Is the stronger WTNH-DT REAL VHF channel 10 , Virtual channel (8.1) , ABC , at about 173 degree magnetic compass received through the side and back of the Y5-7-13 antenna ??
Are both WWLP and WTNH received??
Here is how to aim antennas ,
