Pole Mounting
The 27013720 antenna can be mounted on a pole. The wall thickness of the pole should be no less than 2.5 mm. A 50 mm diameter pole made of round steel is usually used.
- The antenna must be installed in a place far away from high-voltage power supplies or radio signal interference sources (such as other APs or antennas).
- Do not install antennas in bad weather conditions, for example, during rain, snow, or strong winds.
- Install the clamp components.

Use an S=13 mm wrench to assemble the mounting flange and fastener into an antenna mounting bracket with a reference torque of 188 kgf.cm.
- Install the antenna on the pole using the antenna mounting bracket. (with a diameter of φ34 mm to φ114 mm, prepared by customers)

Installing the Pole and Lightning Rod
Carry out the following steps:
- Weld the lightning rod to the top of the antenna pole.
- Install the antenna pole on a parapet or concrete bed on the roof of the building.
- Use a 40 mm x 4 mm flat piece of steel to connect the antenna pole to an earth mat.
- Secure the outdoor directional antenna to the pole using an antenna support. Keep the pole vertical during the installation.
Take note of the following points when installing an outdoor directional antenna:
- If the roof of the building is surrounded by parapets of no less than 1.2 m high, fix the pole on a parapet with expansion screws, and then fix the outdoor directional antenna on the pole with an antenna support.
- If the roof of the building is surrounded by parapets of less than 1.2 m high, fix one of the installation points of the pole on a parapet and the other installation point to the roof with expansion screws, and then fix the outdoor directional antenna to the pole with an antenna support.
- If there are no parapets around the roof, fix the pole to the ground or a concrete bed with expansion screws and steel wires, and then fix the outdoor directional antenna on the pole with an antenna support.
Figure 44-5 illustrates how an outdoor directional antenna and a pole are installed.
The following figure shows the protection area of a lightning rod. The entire antenna must be within the 45-degree protection area of the lightning rod.
If an antenna is installed on a metal pole such as a steel pole, you do not need to install a lightning rod, as shown on the right in the preceding figure.
Outdoor AP Installation Scenarios
Figure 44-6 shows an outdoor AP installation scenario. The distance between a 2.4 GHz antenna and a 5 GHz antenna must be more than 0.5 m.
The distance between two single-polarized antennas of the same AP should be more than 0.5 m, and the two antennas should cover the same area, as shown in Figure 44-7.
