Installation Notes
1. Fix the antenna director and vibrator reflector on the corresponding position of the main pole.
2. Fix the clamp square tube on the clamp with the provided screws.
3. Align the fixing hole on the other end of the clamping square tube with the clamping fixing hole on the antenna, and fix the antenna with screws.
4. Connect the feeder and wrap the connector of the feeder with waterproof tape.
5. Fix the cable with cable ties, and do not let the falling force of the feeder be applied directly to the antenna connector.
6. Before the cable enters the room from the outside, an anti-backflow section should be formed to prevent rainwater from entering the equipment along the feeder.
安装说明:
1、将天线引向器、振子反射器固定在主杆对应位置。
2、将夹码方管用配备的螺丝固定在夹码上。
3、夹码方管的另一头的固定孔对准天线上的夹码固定孔，用螺丝固定天线。
4、连接好馈线，并将馈线接头用防水胶带包好。
5、用扎带固定好电缆，不要让馈线的下坠力直接施加在天线接头上。
6、电缆从室外进入室内前要形成防倒流段，以免雨水沿馈线进入设备。
FAQ
Q1: Can I order a custom 200Mhz Yagi directional antenna? My COFDM transmitter frequency range is 200-230Mhz.
A1: It can be customized.
However, the frequency of 200-230Mhz is relatively low, so the Yagi directional antenna will be longer and the shipping cost will be more expensive. Please refer to the link below.
Sam –
With 12dBi gain and an ultra-narrow beam width, this Yagi antenna provides reliable COFDM reception within a 15km radius. Ideal for drone surveillance in dense urban environments; it maintains a perfect signal even with significant multipath interference.
