Here is how to point Tv antennas ,
http://www.kyes.com/antenna/pointing/pointing.html , Two of the antennas show the V shaped angled reflectors , An All Band UHF-VHF-FM and the A Yagi Backed With A Corner Reflector. Removing the reflectors will allow better reception of the stations WQPX and WSMB. What the reflectors do is direct/reflect the UHF signals to the UHF metal receiving elements. But because WQPX and WSMB are coming in at a angle from the back of the antenna , the reflectors are partially blocking those signals. As others often do , please do not get your self all tangled up with thinking that prevents you from doing things.
