3.3.2 Line-of-Sight and Path Clearance Guidelines
The Lynx radios will not operate properly unless they have line-of-sight between their corresponding
antennas. The Lynx radio transmission will not pass through trees or other obstacles. Factors to
consider include:
- Earth curvature
- Future growth of trees
- Height of buildings
In addition to the line-of-sight requirement, a well-engineered path will also have additional path
clearance to allow for signal loss due to partial obstructions, atmospheric ducting and ground
reflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated and
this distance added to the path clearance (in addition to trees or buildings).
