Being that you are in FL, that flat land allows most horizon to horizon sky for you. Unlike for me, where valley walls block better than 30% of the sky. So, I'd suggest that to aim straight up. When you hear the various calls coming in, like 8-land, 9-land, 3-land, 4-land, etc., that will give a clue where to point the beam at. Just the other night, I heard the ISS X-band Repeater, 437.800MHz FM, with an indoor 3 ele 440 beam, pointed at our local FUSION repeater. Hearing all those 9-land calls then, lead me to believe that I was RX'ing off the rear of the beam with an S2.
