The Basics Part 4-3: Sweep at a Tee
The operator is locating a service line that tees into a main line. This sort of sweep guarantees that the operator can compare the signal strength to his left and to his right (Figures 10-11) to get an understanding of how current is flowing in both directions at the tee. So the positioning of the receiver’s antenna within a field is going to dictate what sort of response we get.
