I now have a radioshack $29 roof-type antenna in the attic for HD reception. It works very well, except, adjustment to get ALL stations is very picky. When I get it directed to get good reception on most stations, one other will start to fade out. And so on, so forth. So, I was thinking of getting a second $29 antenna and splitter-ing them together, to aim at that week station(s). Sound possible?
