安装说明Installation Steps
1、把天线上下端锯齿夹码上的螺母、弹垫及平垫拧下，拿下外边的锯齿夹码，将天线有接头的一端朝下，用锯齿夹码抱在外径为￠35～￠75mm的抱杆上，再把拿下的锯齿夹码穿过M8的螺杆，放上平垫、弹垫，然后拧紧螺母。Unscrew and take the screw nuts, the spring washer and flat washer of the sawtooth clamps on the upper and lower sides of the antenna down,then remove the outer sawtooth clamp.Put the end of the antenna with connectors downwards.Then attach the sawtooth clamps to the pole whose outer diameter is ￠35~￠75mm,and place the M8 screws through the sawtooth clamps.Lastly, put on the flat washer and spring washer and screw the nuts tightly afterwards.
2、取下天线接头护盖，连接天线接头，并注意把天线的接头连接端密封好。Take down the connector cover of the antenna,connect the antenna connectors and make sure that you have sealed the connections well.
松开连接两支撑架之间的螺栓，适当地调节天线的倾斜角度，使其接收到的信号为最好，然后拧紧所有螺母。Loosen the bolts that connect the two struts and adjust the inclination of the antenna to the proper position to receive the best signal. At last screw all the nuts tightly.
