Figure 20 Examples Of Radio Paths - WaveRider LMS4000 User Manual

To illustrate the impact that proper siting of the CCU has on the LM4000 radio coverage,
consider the three cases shown in
• Case 1 is a clear, unobstructed path between the CCU and the EUM, with full Fresnel
clearance.
• Case 2 is a clear, unobstructed path, except for the last few hundred meters, which is
obstructed by foliage and terrain.
• Case 3 is obstructed in the vicinity of the CCU for the first few hundred meters, and
then clear and unobstructed to the EUM.
