The RDF (Radio Direction Finding) vehicle shows the loop antenna spinning like a radar antenna. RDF equipment does not spin their antenna. Normally, the operator would rotate the antenna slowly by hand, finding the two opposite directions where the signal disappears. The operator then knows the transmitter is in one of those directions and draws a line on a map/chart. The vehicle is moved to another location and obtains another direction line. Approximately where the lines cross is the location of the transmitter. This is the reason that smart underground operatives would keep their transmission short and move frequently to avoid detection.
