Effects of Depth, Pitch, and Topography on
Distance Between FLP and RLP
Because of the transmitter’s field shape, the deeper the transmitter is, the further apart the FLP and RLP
will be. The distance between the FLP and RLP with respect to the location of the LL is also a function of
the transmitter pitch and the topography.
When the transmitter pitch is negative, the FLP will be further from the LL than the RLP (see figure
below). When the transmitter pitch is positive, the RLP will be further from the LL than the FLP. If the
ground surface or topography slopes significantly, the locations of the FLP and RLP will also be affected
with respect to the LL even though the transmitter itself is level.
Effect of Pitch on Distance Between FLP, RLP, and LL
Note how the RLP and FLP are at different distances from the LL when the transmitter is
at a negative pitch (compare with figure on previous page in which transmitter is level).
