the utility and the Receiver.
7.10 Congested Areas -
If you suspect that coupling from adjacent utilities is causing
interference in the signal picked up by the Receiver,
try increasing the strength of the signal on
your utility and decreasing the strength of signal from the interfering utilities by:
1
Changing to a different transmitter coupling point or coupling mode. Try another
approach. Move the Transmitter so you are locating from a less congested area into the
congested area. See Figures 7-6 and 7-7.
2
Improving the ground connection or moving the grounding point.
3
Determine the location of the adjacent utilities. Then check to be sure that neither the
direct connect cable or the ground cable cross over any of the adjacent utilities.
Reposition them if necessary.
4
If you are inducing, you can decrease the interfering signal by changing the position of
the Transmitter. Find the location of the interfering utility. Stand the Transmitter on its end
(vertically) over the interfering utility. This will reduce or eliminate signal on this line.
