5. Installation
5.1. Line of sight test
Before you install the device to a mast tube, verify visually that the view in direction of the remote unit
is unobstructed. Watch out for these obstacles in particular:
•
Free Fresnel zones. Signal needs space wider than the diameter of the antenna.
•
Trees at the lower end of the Fresnel zone. They will be 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.
5.2. Antenna mounting
5.2.1. Mounting methods
•
according to the method of mounting on the mast tube
○ right-side mounting
○ left-side mounting
•
according to the method of mounting the FOD unit – antenna polarization
○ horizontal mounting
○ vertical mounting
In both cases mount the unit with the connectors facing downwards at an angle.
