When would the 91XG be specifically recommended over vs. say the Channel Master 4221HD? I can accomodate either one on the roof, and I have a rotator that works. I suppose my concern is that the 91XG just looks a bit lighter in build quality, but I've read a lot of happy people using it to pull in both local and distant signals. - I could get a few local ones with an indoor antenna, but I like to sometimes try to get the further ones- it's fun. A local store has the Channel Master 4221/4228HD's but not the 91XG- or any other Antennas Direct products. Thanks.
