I was wondering if I could combine two winegard OTA Antennas with a diplexor. I want to do this because the one gets FOX 29 HD here and the other one doesn't. They are at two different locations on my house. The one that doesn't get fox is all the way on the third floor roof. The other one is on my porch roof and gets fox but the cbs signal is weak. I have tried adjusting that one and its just doesn't get as good of a signal as the one of the third floor roof. I don't have a big ladder or want to go up there as I am afraid I might slip and fall due to snow and ice.
