Site Acceptance Checklist Notes
The following notes provide important additional information about the Site Acceptance Checklist.
1.
Antenna Mounting
o
Mounting pole is of sufficient height to clear local obstructions, such as parapets, window
cleaning gantries, and lift housings.
o
Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety
hazard. No person should be able to walk in front of, or look directly into the path of the
microwave radio beam. Where possible, the pole should be away from the edge of the
building.
o
Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause
problems during antenna alignment.
o
Mounting pole is grounded as per site specifications. All operators and site owners have
specific requirements regarding the grounding of installations. As a minimum, typical
requirements are such that any metal structure must be connected to the existing lightning
protection ground of the building. Where it extends beyond the 45-degree cone of
protection of existing lightning conductors, additional lightning protectors should be
installed.
o
All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.
2.
Antenna
o
Antenna is grounded as per site specifications. See the third point in the Antenna Mounting
section above.
o
Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an
antenna of 1.2 m or larger, an extra sway brace is fitted to the mounting frame of the
antenna. This sway brace should not be mounted to the same pole as the antenna, but
should be installed directly back to the tower or an alternative point.
o
Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas
have moisture drain plugs installed at various points around the antenna. The purpose of
these plugs is to allow any moisture that forms on the inside of the antenna or radome to
drip out and prevent a pool within the antenna. Only the plugs at the bottom of the
antenna, after installation, should be removed. All other plugs should be left in position.
3.
ODU (Outdoor Unit)
o
The ODU is grounded as per installation instructions. See the third point in the Antenna
Mounting section above.
o
The ODU polarization is as per link requirements and matches the polarization of the
antenna.
o
The main traffic connections are correctly terminated and crimped as per cable and
connector manufacturer instructions. All fiber optic patch leads should be routed carefully
and efficiently, using conduits to prevent damage to the cables.
o
All other user terminations are secure and correctly terminated.
o
All labeling is complete as per site requirements. Labeling is specific to each customer. At a
site with only one installation, labeling may be unnecessary. However, at sites with
multiple installations, correct and adequate labeling is essential for future maintenance
operations.
Typical labeling requirements include:
