Installing the Antenna
Figure 5
Antenna Installed on a Dropped Ceiling Bridge Assembly
Follow these steps to install the antenna above a suspended ceiling.
Step 1
Identify the location in the ceiling where you want to install the antenna.
Step 2
Remove the ceiling tiles adjacent to the T-rails where you will install the ceiling bridge assembly.
Step 3
In the mounting kit, locate two bridge clips and 4x40 Phillips head screws.
Step 4
Place the bridge clips on the bridge so that they are 2 3/8 in. (6.03 cm) apart.
Step 5
Temporarily secure the clip to the bridge with a short length of masking tape.
Step 6
Position the antenna so that the two rectangular slots are aligned with the clip tab that has no holes.
Step 7
Carefully move the antenna so that the clip tabs are fully inserted into the rectangular slots.
Step 8
Start a 4/40 Phillips head screw into each of the holes in the clip tabs.
Step 9
Use a Phillips head screwdriver to secure, but not tighten, the screws.
Step 10
Remove the masking tape from the clips.
Step 11
Verify that the antenna is attached to the bridge where you want it to be. If it is not in the correct position,
carefully slide the antenna until it is.
Step 12
Tighten, but do not overtighten, the Phillips head screws.
Step 13
Install the bridge in the ceiling.
Step 14
Connect the antenna cables to the access point or extender cables.
Step 15
Replace the ceiling tiles.
Suggested Cable
Cisco recommends a high-quality, low-loss cable for use 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 determines the amount of
signal loss (the longer the run, the greater the loss).
