The communication antenna has been used outdoors for a long time, and sometimes it will encounter bad weather, so it needs regular inspection and maintenance. 

In addition to troubleshooting, it is also necessary to take corresponding maintenance measures, the paint-off parts should be repainted, the lubricated parts should be refueled regularly, and sealants and insulators should be replaced in time if aging. 

In addition, a comprehensive performance test is generally carried out every three months, and records are archived. 

Communication antennas are both traditional mechanical and electronically controlled. In use, due to objective conditions or long-term use, there will be some anomalies or failures from time to time, and some common faults are easier to judge and deal with. 

Joint seal aging, water vapor entry will affect the signal transmission, re-ｒｅｐｌａｃｅ the sealing parts, and sometimes part of the cable may have to be replaced. 

New sources of interference have emerged nearby, such as new high-rise buildings, which affect the antenna and need to be replaced. 

Poor de-soldering connection of the cable head will result in occasional signals, which need to be re-welded and the cable head replaced. 

If the communication antenna is seriously damaged by external force and cannot be solved by itself, it can only be sent back to the factory for repair, and serious damage can only be scrapped.
