I am considering the purchase of a bow-tie antennas. I live in a near suburb just outside of the Washington, DC city limits and would like to know whether the 4-bay bowtie will do just as well or better than the 8-bay bowtie. Also, Winegard's website mentions that a new line of HDTV antennas will be available soon, but doesn't say what type of antenna they will be. Would it be better for me to wait for a new HDTV antenna model instead of getting the bowtie antenna now? I want to avoid use of a rotor so I would like an antenna that is not very directional ?
