Account for clearance around the direct line, seasonal foliage and stable mounting positions.
A clear view between two wireless bridge endpoints is a useful starting point, but it is not a complete path assessment. Radio propagation also depends on clearance around the direct line, commonly considered through the Fresnel zone.
Understand the practical implication
Ubiquiti’s wireless training guidance explains line of sight and Fresnel clearance. For a property owner, the important point is that a tiny visible gap between branches may still be unsuitable for a reliable link.
Inspect the route over time
Consider leaves, growing vegetation, parked vehicles and moving objects. A winter installation can behave differently when trees fill out. Record obstacles along the route rather than checking only what is immediately beside each radio.
Use a proper link plan
The necessary clearance depends on the link’s frequency and geometry. Have a competent installer assess mounting height, legal radio settings and supported equipment. Do not use a single generic clearance number for every distance and product.
Check mounting stability
- The support should remain secure in expected weather.
- Alignment should not change with ordinary movement.
- Cable entry and power must suit outdoor use.
- Maintenance should be possible without unsafe access.
Validate beyond a link light
Measure sustained traffic in both directions and observe the connection during representative conditions. A brief successful association does not demonstrate the stability needed for work calls or remote equipment.
Keep the installer’s alignment and signal records so later changes can be compared. If deterioration follows foliage growth or a new obstruction, that evidence can direct the next inspection.
Do not improvise unsafe roof work or alter trees without the relevant authorization. If a suitable radio path cannot be established, compare a professionally installed cable route or another location. A reliable bridge starts with a realistic path design, not a promise that enough transmit power will overcome every obstruction.
