Is it possible to have more than one off air antenna with my VOOM ? and if so how do I go about doing ? I have the winegard sensor antenna and I want to add another . I live 40 miles from Cincinnati and 60 miles from Indianapolis and I want to get both locals so I thought I would add a Radio shack UHF 75 antenna. I just need to know how to go about combinning the two when My diplexer only has one input for antenna and two for sat???
