Well you are not in a good spot for digital. Here is your digital profile from
www.antennaweb.org, but I had to go up 100 ft to get this data. At ground level it shows only one analog channel (WSPA CBS out of Spartanburg).

Most digitals are west of you but nearly 60 miles away. The only VHF is PBS out of Greenville, so unless you really want it, I'd go for a Channel Master 4228 or an Antennas Direct XG-91 with a CM 7777 pre-amp on a mast as tall as I can get and point it west to see what I get.
Also be aware that WLOS-DT and WSPA-DT are above channel 52, so they will likely move back to their old channel (both VHF) in Feb of 2009.
