Site Acceptance Checklist Notes
The following notes provide important additional information about the Site
Acceptance Checklist.
1 Antenna Mounting
•
Mounting pole is of sufficient height to clear local obstructions, such as
parapets, window cleaning gantries, and lift housings.
•
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.
•
Mounting pole is secure and perpendicular. A pole that is not perpendicular
may cause problems during antenna alignment.
•
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.
•
All steelwork is Galvanized or Stainless Steel, as appropriate to prevent
corrosion.
2
Antenna
•
Antenna is grounded as per site specifications. See the third point in the
Antenna Mounting section above.
•
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.
•
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 RFU (Outdoor Unit)
•
The RFU is grounded as per installation instructions. See the third point in the
Antenna Mounting section above.
•
The RFU polarization is as per link requirements and matches the polarization
of the antenna.
