Looks like you are right on the edge of
WDVR's reception area. I agree with AD Tech about keeping the FM separate from the TV system. Use RG-6 coax to help preserve the weak signal from WDVR. While the ST-2 antenna is a really good product, you will likely need a more directional antenna like
this one to receive WDVR more clearly & help reject the stronger adjacent signals.
