Cisco Aironet 1400 Series Outdoor Wireless Bridge 9-dBi Omnidirectional Antenna
78-15545-01
Aligning the Antenna
Follow these steps to mount the antenna to a mast.
Step 1
Assemble the aluminum bracket to the mast with the 1/4-20 x 2.5 in. pipe U-bolt. Install the washers in 
the following order:
a.
Flat washer
b.
Spring lock washer
c.
Nut
Step 2
Tighten the U-bolt nuts hand tight, then use a 7/16-in. (11-mm) wrench to tighten them securely to the 
mast. Do not overtighten.
Step 3
Insert the top of the antenna upward through the cast aluminum bracket until it is positioned as shown 
in 
. Make sure the drain holes are exposed.
Step 4
Use a 5/32-in. (4-mm) hex head wrench to tighten the 5/16-18 socket head set screw to hold the antenna 
in place. Do not overtighten.
Step 5
Position a small level on two sides of the antenna 90 degrees apart and make sure the antenna is truly 
vertical.
Step 6
Connect the antenna coaxial cable to the bridge’s Type-N antenna connector.
Step 7
Form a drip loop in the cable.
Step 8
Tighten the antenna connection until it is hand-tight.
Note
If you prefer to tighten the antenna connection, use a torque-limiting tool like those listed in the 
Tools and Equipment Required section and tighten it to 14-inch pounds. 14-inch pounds is 
basically the torque a person can achieve using one hand.
Step 9
Use coaxial connector sealing compound to make the bridge antenna connection weather-proof. Follow 
the instructions supplied in the Cisco Aironet 1400 Series Wireless Bridge Mounting Instructions.
Aligning the Antenna
With the exception of the following, no antenna alignment procedures are required:
Verify that nothing obstructs the line of sight between the antenna and the devices to which it 
associates.
Ensure that the antenna is mounted vertically.
Note
A comprehensive discussion of antenna alignment theory and procedures is contained in the Cisco 
Aironet 1400 Series Wireless Bridge Mounting Instructions.
