Pole Mounting
The 27011016 antenna is 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.
Fixing the Antenna to the Pole
- Select mounting kits based on pole diameters.
- When the diameter of a pole is 40-65 mm, use U-type bolts.
- When the diameter of a pole is 65-92 mm, use small hose clamps.
- When the diameter of a pole is 92–114 mm, use large hose clamps.
- Keep the polarization arrows pointing upwards during installation. In the following figures, A indicates horizontal polarization and B indicates vertical polarization.
- Finally, tighten all nuts. The recommended torque is 7.6 N·m for M6 nuts.
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 20-5 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 20-6 shows outdoor AP installation scenarios. The distance between a 2.4 GHz antenna and a 5 GHz antenna must be more than 0.5 m.
