Cisco Aironet 14-dBi Vertically Polarized Sector Antenna (AIR-ANT2414S-R)
78-16403-01
Generally, the higher an antenna is above the ground, the better it performs. Good practice is to install
your antenna about 5 to 10 ft (1.5 to 3 m) above the roof line and away from all power lines and
obstructions. If possible, find a mounting place directly above your wireless device so that the lead-in
cable can be as short as possible.
Hardware, Tools, and Fasteners Required
A mast mounting installation kit is shipped with the antenna and consists of the following hardware.
• Upper mounting bracket (adjustable)
• Lower mounting bracket (fixed)
• Mast mount clamps
• Four 4.0-in. (10.1 cm) ¼-20 hex head bolts with flat washers, split lock washers, and hex nuts
• Four ¾-in. (1.9 cm) ¼-20 hex head bolts with flat washers, split lock washers, and hex nuts
• Four ¼-20 hex nuts with split lock washers
You will need two 7/16-in. deep well sockets or wrenches to install the antenna. Figure 1 shows the
mounting bracket assembly.
Installation Process
The following sections contains typical procedures for installing the antenna on a mast. Your installation
may vary. The process consists of the following procedures.
• Assembling the mounting brackets
• Attaching the mounting brackets to the antenna
• Mounting the antenna
• Aligning the antenna
• Grounding the antenna
Before you begin, refer to Figure 1 and Figure 2 to become familiar with the installation.
Assembling the Mounting Brackets
Two mounting brackets are provided; one is adjustable and the other is not. Figure 1 shows the adjustable
bracket. The assembly process is the same for both brackets. Follow these steps to assemble the
mounting brackets.
Step 1 Position the mast mount clamp plate inside the antenna bracket.
Step 2 Insert two ¼-20x ¾-in. hex head bolts into the holes in the mast mount clamp plate facing outward as
shown in Figure 1.
Step 3 Place a flat washer and split lock washer on each hex head bolt.
Step 4 Start a ¼-20 hex nut on each hex head bolt and tighten hand tight.
Step 5 Place a flat washer on two 4-inch ¼-20 hex head bolts.
Step 6 Insert the bolts into the holes facing outward in the mast mount clamp plate.
