According to TVFool.com, you are about 45 miles from the Orlando transmitters, which are all south of you. The signals are fairly strong, but the trees may have an adverse effect on your UHF stations. I would suggest mounting a Winegard HD-7696P on your roof aimed at 175 degrees by your compass. Run the coaxial cable from the antenna to a central location in your house where you can distribute the cables to each TV set, then use a distribution amp-splitter like a Channel Master CM3414, then make the connections to the TV sets, and scan each TV set for signals: you'll get excellent reception from all of the Orlando stations.
