Just connected a Radio Shack omnidirectional antenna and overall I am pleased with the results. I get my locals except for WYTV the ABC afilliate which is only 9 miles from my house. I do pick up a cleveland ABC station which is over 50 miles from my house (go figure). The question I have is it comes with a "power injector" which makes a big difference when I plug it in but is there any other after market amplifiers which would work better or can you add another in line amp along with the original that came with it.
