27011333 Installing Antennas

27011333 antennas are directly installed on APs.

• Connectors of 27011333 antennas must be installed in the right direction. You should comply with the following installation instructions.
• To achieve the optimal coverage effect, it is recommended that you install the omnidirectional antenna four to six meters above ground.
• It is recommended that you connect a 50 ohm RF load to an idle antenna interface and wrap the RF load with both the insulation and waterproof tape.

1. Install the wire thread insert to the antenna port on the AP. Ensure that the two red surfaces in the following figure are on the same horizontal plane.

2. Manually tighten the wire thread insert in the direction of the arrow shown in the following figure. Then use a torque wrench to tighten it with a tightening torque of 10 N m to 15 N m.

If the two surfaces are not on the same horizontal plane when you tighten them, the antenna cannot be tightened securely and signal transmission will be affected. In this case, loosen the antenna and adjust its position and then tighten it again.

The following figure shows the antenna installation.

• It is recommended that you connect a 50 ohm RF load to an idle antenna interface and wrap the RF load with both the insulation and waterproof tape.
• Wrap the connectors in single-layer PVC insulation tape, triple-layer waterproof tape, and then triple-layer PVC insulation tape.
• Before wrapping the waterproof tape, stretch the tape evenly until the tape length is twice its original length. With each layer of tape wrap the cable tightly and ensure that each layer covers more than 50% of the layer beneath it.
• Wrap the triple-layer tape from bottom to top, from top to bottom, and then from bottom to top again.
