Clearstream 2V from Walmart and possible amp should get all major Charlotte stations, as well as WTVI. And you should also receive Greensboro with a good UHF antenna and amp if you choose. Perhaps an 8-bay or 43XG. There is DB8e, CM-4228, and generic versions from MCM and Solid Signal that are lower priced. And the Antennacraft HBU-33 from RadioShack could also be a good choice. But should post in Charlotte OTA thread.
