I was wondering if anyone out there could tell me what is a better antenna to purchase to get over the air HDTV? I have been looking at the traditional "V" shaped ones (UHV?VHF) and also the square "bowtie" antennas. I am wanting one that has a range of at least 50 miles. Any thoughts on which one I should go with and maybe a site to get one at a good price? Thank you for your help.
