RDL-2000 Installation Guidelines

The RDL-2000 will also function under optical line-of-sight (OLOS) conditions; where a

clear straight line path exists between the two end points, but the first Fresnel zone is

not

clear. If the optical path is completely blocked, it may still be possible to establish a

non line-of-sight (NLOS) path using reflections and diffraction. A satisfactory multipath

RF signal may be obtained by directing both RDL-2000 antennas towards a reflective

structure that is within sight of both units.

The path profile should include the following information:

Antenna Description

Location Instructions to identify the location for installing the antenna.

May include blueprints and specify material list.

Height Mounting height for antenna.

Azimuth Horizontal aiming direction for the antenna (magnetic or GPS compass)

Elevation angle Vertical aiming for antenna (spirit level).

Expected RSSI

Use the Link Budget tool to determine the expected receive signal

strength indication (RSSI).
