Pinpointing a Pig's Precise Location

Once the general vicinity of the pig has been located, it is now time to find the exact location of the pig.
This can be done by switching the orientation of the CD42-GP antenna to an angle perpendicular to the
pipeline (Figure 83). This means holding the antenna in such a way so that the end of the antenna is
pointing at the transmitter.
