CONSTRUCTION METHOD OF SIMPLE CONSTRUCTION TYPE ANTENNA TOWER

PURPOSE:To build an antenna tower in a short time and to start communication by adopting the structure for an antenna tower that it is stood by itself under a predetermined wind pressure, communication is attained through a line after the construction is finished, and then stays are given to the said antenna tower so as to reinforce against a further stronger wind pressure. CONSTITUTION:Legs 6 are set at the construction site, the height of the legs 6 is made higher than the bed of a truck by operating a handle 8, the truck is moved from the antenna tower, then the height of each leg 6 is adjusted by operating the handle 8 succeedingly for level adjustment so as to match a base 7 to a horizontal face. Then a winch (not shown) winds up a wire 9 to raise the antenna support tower 1 as shown in the arrow A and then to expand it as shown in the arrow B. Then the direction of the antenna 2 is set in a prescribed direction by manual or remote operation, the antenna tower is used as a self-supporting tower and a communication line is opened. Then the strength of the antenna tower is decided for the wind pressure corresponding to a wind speed of 20m/s and stays are used to reinforce the tower against a wind speed more than the wind speed.
