6. Installation
6.1. 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 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.
6.2. Antenna mounting
6.2.1. Mounting methods
• Mounting on the mast tube can be achieved by:
○ right-side mounting or
○ left-side mounting
• Mounting the FOD unit for antenna polarization can be achieved using:
○ horizontal RX polarization mounting or
○ vertical RX polarization mounting
In both cases mount the unit with the connectors facing downwards at an angle.
