For a link of 4 km, at 3.5 GHz produces a first Fresnel Zone radius clearance of about 9.3
meters, meaning the antennas should be mounted at a height of at least 5.6 meters (60%
of 9.3 meters) above ground level (or clutter level).

For a link of 4 km, at 4.9 GHz produces a first Fresnel Zone radius clearance of about 7.8
meters, meaning the antennas should be mounted at a height of at least 4.7 meters (60%
of 7.8 meters) above ground level (or clutter level).
3.4.3 Radio Antenna Alignment
Once the ProST is installed and aimed in the general direction of the base station, it is
recommended to measure the received signal strength (RSS) to determine the signal strength
received from the base station, and to precisely align the ProST for maximum signal strength. You
need to orientate (up/down, left/right) the ProST until the maximum RSSI levels are achieved, and
then secure the ProST. For viewing RSS values, see "Web-based Management" for standard
alignment, for finer alignment, see
