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.
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.
