I recently purchased a new antenna from HH Gregg. It's an RCA (the only brand they carry) and is working better than my old antenna. They have a 10-day return policy. I would really like to get the Zenith Silver Sensor (or similar) to compare to it. However, I want to purchase this locally for returnability reasons. Any suggestions on where I could buy these? I've checked the websites for most of the big chains around here and haven't had any luck. I live just outside Charlotte, NC, so I'm in a pretty big market. Please let me know if you have any suggestions. Thanks!
