The DB8 is a Very Directional antenna in the forward direction , receives nothing on the sides and very little at the back of the antenna due to the reflector screens reducing reception to the >< shaped reception elements.
Your location has receivable Tv stations/channels , north , north west , west , south west , south and east.
A much better antenna for your location is the ANT751 mounted above the roof , aimed at about 0 degree magnetic compass (north).
