A positioning structure of an inner and an outer insulation sleeve member for an antenna, the sleeve members are an outer insulation sleeve and an inner insulation connecting rod insertion connecting with each other to form the main housing of the antenna, wherein, the inner connecting rod has thereon an upper and a lower protruding rib in corresponding respectively to an upper and a lower inner annular recess provided on the outer sleeve. The lower inner annular recess and the lower protruding rib had better be both in a truncated conical shape flared downwardly to form an abutting shoulder to help guiding for insertion connecting and to prevent slipping off of them by an axial pulling force. The inner connecting rod has thereon notches corresponding in position to the pending tongs on the top of the outer sleeve; and the inner and the outer sleeve members can synchronically be positioned in the peripheral direction.
