The 50 degrees is inbetween the Tv stations to the north/east and east.
The Tv is required to rescan when adjusting the antenna to find new channels.
Aim the antenna directly at WNJS Real UHF channel 22 , virtual channel 23 , PBS , at 99 degree magnetic compass and rescan.
Is WNJS received now??
Here is how to aim antennas ,
