A jin-pole or gin pole is a rigid pole with a pulley on the end used for the purpose of lifting. The lower portion of the jin-pole is attached to the upper exterior of an existing tower or structure. The jin-pole's free end extends above the existing tower or structure. When used to create a segmented tower or antenna, the jin-pole can be detached, raised and re-attached to the just completed segment for the purpose of lifting the next segment. The process is repeated until the top most portion of the tower is completed.
