Communication tower or communication tower is a kind of signal transmission tower, also known as wireless signal tower and microwave transmission tower. Its main function is to support the transmission and transmission antenna of microwave, ultrashort wave and wireless network signals. It is widely used in railway wireless train dispatching, China Mobile, China Unicom, telecommunications, radio and television, military, transportation, radio management committee and other communication departments.
1, Characteristics and application of communication tower
1. The communication tower is divided into ground communication tower and roof communication tower according to the erection position. Whether the user chooses to build the tower on the ground, hills, mountains or roof, it plays the role of raising the communication antenna.
2. Increase the service radius of communication or TV transmission signal. Generally, the communication antenna is placed at the highest point to increase the service radius, so as to achieve the ideal communication effect. Therefore, the communication tower plays an important role in the communication network system. In addition, the roof communication tower also plays the functions of lightning protection and grounding, lighting decoration, aviation warning and so on.
2, Production process
The communication tower is composed of iron tower foundation, lightning protection, tower body, working platform, ladder, antenna support and other steel components, which are hot-dip galvanized for anti-corrosion treatment, and the service life is 30-50 years.
