Site selection requirements
The performance of the SkyZhone 45 system depends upon its proper
installation. A good installation conforms to these guidelines:
• The antennas are installed in line-of-sight of each other, with adequate
clearance.
• The antennas are mounted to stable structures.
• There is dependable, protected and easily accessible power at each site.
• The coaxial connection between the IDU and ODU is no longer than 300
ft.
Antenna path guidelines
The SkyZhone 45 wireless transport will not operate properly unless you can
see each antenna from the other. High frequencies used cannot pass through
trees or other obstacles. In general, consider the following when calculating
line-of-site between the antennas:
• The curvature of the earth.
• Buildings and trees.
• Future tree growth and construction.
