I've scanned for channels. I've picked up 7, 29, 21 (bad signal), and 38. I picked up channel 40 but not this time
The antenna is facing the NNW direction.
Also according to http://transition.fcc.gov/mb/engineering/maps/
The prediction if I had a antenna up to 30 feet above ground level, I can get strong signal of WNEH 38, moderate signals of WJBF 6 (Augusta, GA), WMYA 40, WYFF 4, WHNS 21, WAGT 26 (Augusta, GA), WNTV 29, WYCW 62, WFXG 54 (Augusta, GA), WSPA 7 (which I can get good signal mostly), WRDW 12 (Augusta, GA), WUNF 33, WGGS 16, WLOS 13. Weak signals of WCES 20 (Augusta, GA), WRET 49, WOLO 25 (Columbia, SC), WIS 10 (Columbia, SC), WLTX 19 (Columbia, SC), and WRLK 35 (Columbia, SC). Plus predictions of no signal of WACH 57 (Columbia, SC), WKTC 63 (Columbia, SC), WBTV 3 (Charlotte, NC), WEBA 14 (Allendale, SC/Augusta, GA), WJZY 46 (Charlotte, NC), and WCNC 36 (Charlotte, NC).
Then I went to http://www.antennaweb.org
and typed my address. I could get WNEH 38 with a yellow-colored zone antenna (Small multidirectional outdoor antenna), WMYA 40 with a green-colored zone antenna (Medium multidirectional outdoor antenna), WGGS 16 with a blue-colored zone antenna (Medium directional w/ preamp), WNTV 29 and WSPA 7 with violet-zone antenna (Large directional w/ preamp). Do you rely on those sites tylerSC?
