The HD7694P is recommended because the tv stations are widely spaced to the , north west , west and south west. The forward angle of reception of the HD7694P antenna is wide. The longer and bigger a antenna is , the narrower the angle of reception at the front of the antenna. I think that WITF PBS will be received Ok with one tv connected , however if a little more push on the signal is needed then install a Channel Master CM3410 distribution amplifier.
