Installing the Antenna

Distance Between Bracket Mounting Holes
Step 5
Attach antenna assembly to azimuth bracket, as shown in
Figure 4
.
Step 6
Adjust the position of the antenna to the desired azimuth and elevation angles and tighten all pivot
hardware (4 places) to a maximum torque of 55 in-lbf (6.2 Nm). The bracket allows the antenna position
to be adjustable to +/–45 degrees azimuth and +/–60 degrees elevation.
Note
Cisco recommends grounding the antenna. See the
“Grounding the Antenna” section on page 13
for details.
Antenna Cable Information
If the antenna is used with the Cisco 1552CU or 1552EU access point, the port A of the antenna must be
connected to port 1 of the access point, port B of the antenna must be connected to port 3 of the access
point, and port 2 of the access point must be capped with the cap enclosed with the antenna.
Note
Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable
should be kept as short as possible because cable length also causes signal loss (the longer
the run, the greater the loss).
