i did pick up some lte over that area yesterday. I had LTE Discovery running not sensory so it did not map it.
I was about 60ft up on top of a parking garage
Here are the coordinates:
27.95153045, -82.44850427
I did this quick image showing what the signal strength could look like around USF using the same strength radius from the tower by IHOP. Inner circle would be the darker purple color, outer circle the lighter color.
