Do you currently get WGAL on VHF 8? If not, 9 and 12 are far enough apart a Jointenna may let you merge a VHF antenna pointed at 36 degrees with an all band antenna (or the combined feed from VHF low, VHF high, and UHF antennas) pointed at 122 degrees. http://www.channelmasterstore.com/JO..._p/cm-0579.htm

Blonder Tongue made narrow band UHF yagis that in the range of your UHF signals from 36 degrees covered about 10 channels. 39 to 46 is less than 10 channels, which makes me think it would be possible to design a yagi that would get WFMZ and WLVT well while rejecting most other signals outside the range of channels 37 to 48. Then all you would need to do is trap RF42 from the 36 degree antenna, and RF 39 RF46 from the 122 degree antenna to combine UHF antennas with minimized multipath concerns. (A ΒΌ wave open stub of coax would appear as a short at the frequency it was cut for, but look open further away from the frequency it was cut for, that could be a place to start for making a trap.)
