I suggest a Winegard HD7694P antenna. And a 8 way distribution amplifier , Channel Master CM3418 . And F Type 75 ohm terminators on unused ports of the 8 way distribution amplifier. Direct the antenna at about 202 degree magnetic compass. Yes PBS , KBDI-DT 13 will be received , no problem , a rotor will not be needed for the stations to the south west. Here is how to aim Tv antennas ,
