Mounting the Antenna
A clean, flat surface at least 15 x 15 cm (6 x 6 in.) in area is required for mounting the antenna. Antenna mounting stud has a
Double-D cross-section compatible with the
antenna from rotating while the mounting nut is torqued. It also provides additional vandal resistance by not allowing the antenna
to rotate around the axis.
Follow these instructions to mount the antenna. See
1. Mark the desired location where you plan to mount the antenna, and create a hole through the surface using a McMaster
Carr Double-D Hole Punch P/N 3449A85, or equivalent punch tool. Alternatively, it is possible to drill a circular hole 0.91"
in diameter.
2. Thread the cables through the hole and insert the Double-D mounting stud into the hole. Ensure that the gasket on the
underside of the antenna sits flush against the mounting surface.
3. Place the metal washer and the metal nut onto the stud. Tighten the nut to a torque of 50-65 ft-lb or 68-88 Nm.
Figure 4 shows the vandal resistant antenna mounted to a matching color outdoor electrical utility enclosure of a simple
rectangular box shape. Many outdoor enclosures come in much more complicated shapes, with a number of rectangular boxes
and compartments joined together. In general, it is recommended that the antenna be installed on the highest surface of the
electrical enclosure box. In this manner, the radiation in the upper hemisphere is not obstructed by other nearby geometrical
features of the enclosure.
In many deployments the nodes need to communicate to other nodes located near horizon. Placing the antenna on the highest
enclosure surface is a good way to ensure that horizon communication is not obstructed. If it is not possible or feasible to place
the antenna on the highest surface of the enclosure, please contact your Cisco account representative for support or 3rd party
qualified RF (radio-frequency) professional with experience in antenna installation and siting.
