The wide pattern of the 4-bay suggested by TG is needed for the broadly distributed UHF stations.
is south ot hte OP's location, WMFD
is NW of the OP's location.
If both signals are of interest to the OP, a separate high-VHF like the Winegard YA-1713 or Antennacraft Y-10713 aimed at about 45° would add WMFD to the lineup. WGCT would require it's own antenna as well, the same type high-VHF, aimed at about 170°.
Combining these three antennas is not to difficult, a Channel Master CH-8 Join-Tenna
and a UVSJ would be all the hardware needed. If only CH-8 or only CH-12 is of of interest to the OP, the Join-Tenna is not needed, just a UVSJ.
FWIW: WGCT appears three times in the FCC database
. Once in Tampa, FL and twice in the Columbus, OH area. rabbitears.info also has corresponding entries, with the Tama entry shown as 'off-the-air'. The Colubus entry is here: http://www.rabbitears.info/market.ph...GCT-CD#station
(Leave it to the FCC to have the same call sign show up in multiple locations.)
