I want to be able to get a clean signal from Victoria, which is due south. I also would like to get HD signals from Houston which is 84 miles out East north East... (This would be for my secound home) What I have now is a Radioshack tri-drive antenna that is 20 feet up in the air. I have it right now going to Victoria right now but they do not have any HD signals. I also have a TV antenna on another pole about 20 or so feet up going to San antonio. But, I dont want to put up any more antennas. I would like to have a good decent indoor antenna for Victoria stations, what antenna would anyone recommend? My biggest problem is that house has a metal roof, I know it will be hard for signals to get through, but I know they can if I have the right antenna.
