The reference to elevation AND inclination is a bit curious, I'd be interested in what angles you are using, and how you are measuring them?
For Miami, assuming a latitude of about 25.8, the elevation of your rotation axis should be something around 63.6, and you should be using a declination of about 3.8 (BTW, there is no place on earth that would use a declination of 9 deg). Since you may not be measuring declination directly, but instead the surface of the dish, that elevation would be approximately the 63.6-3.8=59.8, which BTW, is the elevation of your southern most sat.
Anyway, I'd be curious relative to what angles you were using, and how they were measured.
