Cisco Aironet Four-Port Dual-Band Polarization-Diverse Antenna (AIR-ANT2513P4M-N)
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.
1. Follow steps 1 and 2 from the Mounting on a Wall or Ceiling section.
2. 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 ( Figure 5 ).
3. Tighten the clamps only enough to hold the flange and antenna in place until the antenna is positioned to its final position.
4. Assemble the antenna and bracket to the flange as shown in Figure 6 .
5. Position the antenna, mounting bracket, and hose clamps on the mast.
6. Tighten the hose clamps until the antenna is fully secure on the mast. Ensure that the antenna cannot rotate about the mast.
7. 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.
8. After you adjust the antenna position, tighten the adjustment bolts. Tighten all bolts to 18.7 +/- 5 lb-ft (25.4 Nm).
9. 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= (5 foot low-loss
cable with RP-TNC and N-type connectors) for AP3702P, or AIR-CAB005LL-N= or AIR-CAB010LL-N= (5 foot and 10 foot
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).
Painting the Antenna
Painting the antenna and the bracket does not affect its performance if you use standard exterior-grade, oil-based or latex paint.
Do not use metallic or metallic-flake paints, which will degrade antenna performance.
NOTE : Before painting the antenna, cover the pressure-release vent on the rear, lower-left of the antenna with masking tape to
prevent clogging ( Figure 3 ).
Cisco recommends Krylon Fusion for Plastic or Rust-Oleum for Plastic (which might require a primer coat). For best results,
follow the surface preparation suggestions from the paint manufacturer.
