Claims

[Scope of Claim for Utility Model Registration] A reschel wire consisting of a dielectric plate extending in the vertical direction and a pair of conducting wires facing each other through the dielectric plate and extending vertically. , a radiating element connected to the end of the conductive wire near the upper end of the Lecher wire and upwardly on one side of the dielectric plate and downwardly on the other side of the dielectric plate from that point. a first antenna extending vertically, a second antenna having a dielectric plate, a Retzchel wire, and a radiating element like the first antenna; and a second antenna below the radiating element of the first antenna. The above-mentioned mobile station varsity antenna device comprises an elongated cylindrical dielectric cover covering the first and second antennas with the second antenna extended vertically.
