4. Installation

4.1. Line of sight test

Before you install the device to a mast tube, verify visually that the view in the direction of the remote
unit is unobstructed.
Line of sight considerations:
• Free Fresnel zones. Signal needs space wider than the diameter of the antenna.
• Trees at the lower end of the Fresnel zone. They will grow taller in a few years.
• Possible building development.
• Objects in the close proximity of the antenna such as edges of other antennas, their mounting racks,
edges of the roof.

4.2. Antenna mounting

Antenna mounting depends on the antenna vendor, antenna type and the size of the chosen antenna.
The result of any antenna installation is that it is fixed to the mast, pointing to the right direction and its
waveguide and fixing screws are ready for mounting RAy unit to it.
