EXTERIOR SITE SURVEY
When fi rst arriving at the radio site, an external survey of the site and surrounding area should be
conducted to identify any hazards. Actions or repairs that may be required for this or the next site survey
can also be identifi ed.
• Check that the building is in good condition (no cracks, leaks, vandalism or other damage)
• Check the antennas, and antenna structure (tower) for visible damage
• Check the external RF cables and connectors for visible damage or corrosion
• Check the external leased lines and / or power cables for damage
• Check the lightning protection for damage
• Check that there are no obstructions in the area (branches, overgrown brush, etc.)
• Exterior site photographs can be taken
INTERIOR SITE SURVEY
Once the radio site is entered an interior survey of the site should be conducted.
• Check the interior of the building, including the fl oor, for water leaks, animal entry or other
damage
• Check the condition of the cabinet / equipment rack
• Check the internal RF cables and connectors for visible damage or corrosion
• Check the duplexers / combiners / multicouplers for damage, loose parts or corrosion
• Check the internal leased lines and / or power cables for damage
• Check the power supply / batteries / solar panels and ensure they are operating correctly
• Interior site photographs can be taken
RADIO SITE INVENTORY
It is a good idea to fi ll out a complete inventory of all model numbers and serial numbers of the radio
equipment, duplexers, antennas, power supplies and all other equipment at the site when performing
a site survey. Use the Codan Radio Site Inventory to record this information. Codan Communications
suggests that customers maintain a site inventory, as serial and model numbers can help the factory
with any customer support issues.
