Self Supporting Tower Telecom Signal Tower Microwave Communication Antenna

Self Supporting Tower Telecom Signal Tower Microwave Counmunication Antenna Product Description Radio Masts and Towers (Telecommunication Towers) are typically tall structures designed to support antennas for telecommunicationsand broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Monopole Design 1. Design Code YD/T5131-2005, ANSI/TIA-222-G Structure Steel 2.
