This depends on the size of the antenna, and the pattern of the
antenna. With small directional antennas, spaced well above the
guy lines, that statement is most likely correct.
It should not be used as a general rule in all cases.
What you want is the guy line out of the field of the antenna, so
there are many cases where the suggestion above won't work.
