Your report indicates mounting an antenna at 40' AGL. That explains the optimism for good reception. If you can not actually mount that high, you may be disappointed. (I wish I had a 40' tower...)
Presuming you can mount at 40', clear of trees, I would recommend going for the Orlando stations to the NW. I would pick a large high-VHF/UHF combo antenna like the Winegard HD7698 matched with a quality pre-amp such as an HDP-269.

I would hope to see stations as low on the report as WOPX and WTGL.
An alternate solution would be a 91XG (UHF), a Y10713 (high-VHF), combined with a CM7777 preamp (with the FM trap engaged).
