摘要： A vehicle pole antenna fixed to an antenna support base includes: a rod 10, a helical antenna element 20, a joint 30, and a mast cover 40. The rod 10 has flexibility and insulation property and has a concave portion 11 at its base end surface. The helical antenna element 20 has a coated wire wound around the rod 10. A winding density of the helical antenna element 10 adjacent to a bending start point of the rod is lower than that at the other portions. The joint 30 has a convex portion 31 to be fitted to the concave portion 11 formed at the base end surface of the rod 10. The joint 30 is electrically connected with the helical antenna element 20 and connected to the antenna support base.
