Appendix B – Site Survey Information
Planning
When installing a microwave link, proper planning is required. Items to be addressed for proper planning
include:
• RF path planning
• site preparation, including power and LAN
connections
• installation issues for outdoor units including
modem and Radio
• Governing body licensing issues (FCC, etc)
• Check local, regional, and national building
and electrical codes
• lightning and ground
protection
• surge protection
• use of outdoor cabling
• other radio system at the
same frequency
Site Survey
A site visit must be done prior to installation to ensure proper line of sight path clearance exists and that
proper facilities exist at the site according to the details listed below.
Line–of–Sight and Path Clearance. Determine optimum location for the radio. Radio and antenna location
are important to ensure optimum radio range and throughput:
• Install the antenna as high as possible to maximize the range of a building-to-
building connection
• Maintain a clear line–of–sight between Horizon Compact antennas. Obstructions
can impede performance or limit ability to transmit or receive data. Reduced signal
strength could affect performance; and
• Maintain maximum path clearance at both ends for the directional antennas.
When determining maximum path clearance, be aware of objects that restrict performance such as:
• Buildings
• Trees
• Rooftop objects such as a/c units
• Conductive metal surfaces
• standing pools of water
• edges of the roof (parapet) of the building on which the Horizon Compact is to be
mounted.
