Because the differences in elevation might create different propagation paths, as the signals bounce around to reach the indoor antenna, when the receiver is so close to the very elevated transmitting antennas. The difference in transmission frequency is probably the major factor. The differences in wavelength change the effect of multipath(s) on the signal.
