10.2 RF Propagation Planning
Establishing a reliable point-to-point radio link requires system plan-
ning and design. You should have an understanding of the physical
parameters affecting propagation. The following material discusses
these factors and will assist you in designing a dependable transmission
path for your radio link.
NOTE: This section is intended for use as a guideline when planning
transmission paths. It does not consider all of the local condi-
tions that may be present, nor does it guarantee that adequate
signal strength will be obtained in a given system. There is no
substitute for an on-the-air test to verify the predicted path
results, and to check the overall operation of the radio system.
