The hole on a single frequency, with 3 objects (transmitter, receiver, reflector) will be caused by the reflector on the surface of one of some rougly egg-shaped space around the line of sight of transmitter and receiver, where the reflected wave arrives at (multiples of) 180° phase shift compared to LOS transmission, causing some cancellation of a portion of the direct wave energy (destructive interference). Several transmitters, same reflector and same receiver at the same time, those possible areas might overlap somewhere. And this is only the beginning. There is constructive interference, Doppler shift, too...
