Assuming these are parabolic antennae,
They're not, they are solid state phased arrays with a total mean power output in the region of 2.5MW. Unlike the old mechanical dishes, which tended to concentrate transmissions to the north and east, the current arrays are electronically steerable through 360 degrees. Even though the main transmitted beam is set some 3 degrees above the horizontal, field strengths close to international safety limits have been measured on surrounding roads. I wouldn't choose to get too close to it in an aeroplane.
