Telecommunication cable
Engaging in tower manufacturing for more than a decade, our company has longtime experience in the design, manufacture and installment of steel tower mast structure. Main products include all kinds of iron towers and similar steel structures widely used in the fields like power transmission, substations, telecommunication, microwave-communication, radio/tv broadcasting, mapping, watchtower etc.
Telecommunication Towers to structures that are built as a base for installing various types of antennas to receive and transmit electromagnetic waves. Often, the tower is made of metal materials and in the Lattice of a grid to lighten the tower and reduce its windproof surface. At the same time, sometimes metal telecommunication towers are implemented with non-mesh filled surfaces and sometimes they are built using reinforced concrete. Lattice Tele Towers are designed and built with different geometrical shapes, according to the shape of the transverse and longitudinal sections and the arrangement of their constituent members.
With over 30M height; mobile signal could have better propagation and away residential area. It's good idea to provide you better coverage for mobile signal. Monopole also could combine wireless and traffic control system in platform. Mobile phone operators share the monopole also good idea in cost saving.
