help please !!! i have a uhf silver sensor installed in attic of my home - i get great reception on several digital/hd channels from antenna farm located about 6-8 miles from here. there is another digital/hd channel, 5.1, located about 50 miles away in opposite direction which can not not pick up. i would like to install, also in attic, an second, inexpensive vhf antenna to receive that channel, one that i could point to that channel and not have to further adjust thereafter. any recommendations on what antenna to get? also, how would i join the two antennas together to feed into my receiver without having to switch back and forth. would there be any problems with having such a two antenna set-up? any suggestions/advice appreciated.
