PROBLEM TO BE SOLVED: To provide an antenna tower mechanism which reduces operation halt time in a maintenance work of the antenna apparatus and allows to save expenses. SOLUTION: A radome 2 is equipped on top part of the antenna tower 1. Through a circular opening section created on attaching part on the radome 2 to the top part of the antenna tower 1, an antenna apparatus 3 placed on an antenna setting floor surface (top panel) 5 with almost same diameter as the opening section is stored into the radome 2 and operated. On a center section of the antenna tower 1, an elevating device 4 for lifting or lowering the top panel 5 on which the antenna device 3 is placed between the top of the antenna tower 1 and the ground is equipped. When operation of the antenna device 3 needs to be stopped for maintenance work of the equipments, the elevating device 4 is used to let down the antenna device 3 along with the top panel 5 to the ground in order to perform the maintenance work for the antenna device 3 on the ground.
