Say you have the receiver on the top of a downtown building or a tower and you are transmitting from 1500', there's not too much that can get in the LOS. Receive systems can either be a single antenna, a series of antennas, or (like in the link above) a dish inside a radome - the dish generally can rotate the full 360 since the cable slips through the middle.
