Cisco Aironet Four-Port Dual-Band Polarization-Diverse Antenna (AIR-ANT2513P4M-N)

Installing the Antenna
See the Suggested Cable section for cable recommendations.
Mounting on a Pole or Mast
The antenna can be mounted on a pole or mast using two hose clamps.
Note The pole or mast must be rigid enough to hold the weight of the antenna plus the associated
forces produced by wind loads. In addition, the mast must be structurally strong enough to
withstand the clamping force of the hose clamps.
To mount the antenna on a pole or mast, follow these steps.
Step1 Follow steps 1 and 2 from the Mounting on a Wall or Ceiling section.
Step2 Position and mount the mounting flange (Figure 4) onto the pole or mast using the hose clamps provided
in the kit. The hose clamps should pass through the slots on the mounting flange (Figure5).
Step3 Tighten the clamps only enough to hold the flange and antenna in place until the antenna is positioned
to its final position.
Step4 Assemble the antenna and bracket to the flange as shown in Figure6.
Step5 Position the antenna, mounting bracket, and hose clamps on the mast.
Step6 Tighten the hose clamps until the antenna is fully secure on the mast. Ensure that the antenna cannot
rotate about the mast.
Step7 After the antenna is secured on the mast, adjust the azimuth and elevation.
To adjust the azimuth and elevation, use a 1/2 in. (13-mm) wrench to loosen the adjustment bolts.
Azimuth can be adjusted ±25 degrees and elevation can be adjusted ±60 degrees.
Step8 After you adjust the antenna position, tighten the adjustment bolts. Tighten all bolts to 18.7 +/- 5 lb-ft
(25.4 Nm).
Step9 Connect the antenna cables to the access point. The antenna ports are labeled A through D, from left to
right. Connect the antenna port A to connector A on the access point, antenna port B to connector B on
the access point, and so on. See the Suggested Cable section for cable recommendations.
Suggested Cable
Cisco recommends a high-quality, low-loss cable for use with the antenna, such as Cisco
AIR-CAB005LL-R-N= (5ft low-loss cable with RP-TNC and N-type connectors) for AP3702P, or
AIR-CAB005LL-N= or AIR-CAB010LL-N= (5 ft and 10 ft N-type connectors, respectively) for
AP1570. Four cables are required.
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).
