K48DH is a mere 196 watts and is 56 miles away. The odds of picking it up are negligible, regardless of what the simulation says, especially if there is ANY obstruction in the signal path.
Since K48DH also utilizes a 1.75° beam tilt (depresses the main lobe by that amount from the horizontal plane at the transmitting antenna), you are likely "above" the main lobe's coverage pattern even after considering the effects of the relative elevations and the curvature of the earth. The vertical pattern of the transmitting antenna is NOT included in the TVFool simulation which assumes a uniform vertical pattern, therefore it is very likely over-estimating, by a large amount, K48DH's coverage area in more distant areas.
