Installation Instructions
CM-7-60
SW3-769 - v4
1.
Introduction
The CM-7-60-NJ is an ultra-wideband low PIM ceiling mounted antenna covering 698MHz to 6GHz. The antenna features an integrated groundplane and
can be mounted on metallic or non-metallic ceilings. The antenna can be mounted by way of its central bush (CM-7-60-NJ) or utilising optional additional
screw fixings conce
a
led beneath the antenna’s removable valance.
2.
Select a Suitable Mounting Location
The antenna is omni-directional and should be mounted as centrally as possible within the desired coverage area. The roof space should be accessible at
this location to permit routing of cables to the radio.
Select a flat level location on the desired ceiling which is free from obstructions and not too close to other ceiling mounted items - consider downward
projection of antenna and any height clearance issues with low ceilings.
Take care to avoid mounting the antenna in close proximity to metal ceiling furniture such as girders, joists and air conditioning units as these objects may
affect the antenna’s performance.
3.
Mount the antenna
If the ceiling is constructed with removable ceiling tiles, it may be best to remove the tile, mount the antenna, and then re-fit.
Rotate and remove the antenna’s outer plastic valance cover from the central cover to expose the antenna base plate and mounting holes (
Fig 1
).
Mark the position of the mounting holes & RF connector, using the base as a template.
Drill the holes for the mounting screws and RF connector. Alternatively if mounting to an appropriate material self tapping screws can be used. Screws
should be countersunk to avoid interference with the antenna valance.
Remove the thumbscrew nut, mount the antenna base plate on the ceiling tile and replace the thumbscrew nut tightening it firmly. (
Fig 2
) Utilise counter-
sunk screws (Fig 2) to secure the installation. Replace and rotate the outer antenna valance cover back into place.
