i need a little help with my set-up . just for a little info , i live in an area where i can receive tv signals from both Chicago ill and south bend in , but problem is to get them , i have to have one ant set up one one side of my roof and another ant. set up on the other side of my roof, now when i hook just one or the other to my tv i get a good signal and all the channels from there respective cities, but i need a way to hook them both into one, i have tried a coaxial combiner from radio shack but i lose all the dig/ hd stations from south bend. the down lead going to my tv if next to one of my legs for the ant that i have pointed to Chicago and i have been running the line from the other ant over to there and hooking it in there and a winegard ps-7070 amp that's hooked in by the tv

any help with how to get it to work would be gladly accepted
