PROBLEM TO BE SOLVED: To provide a VHF-UHF common antenna which can receive the VHF low and high bands and also the UHF bands in good conditions and can be totally formed compact without drawing a lead wire out from an antenna box. SOLUTION: A parallel element part 13 of this antenna includes a main element 11 and an auxiliary element 12 which are fixed in parallel to each other with a fixed space secured between them. The base end of the element 11 is connected to an antenna base 10, and the tip of the element 11 is connected to the element 12 via a parallel resonance circuit 21 which is placed in series to an intermediate fixing member 14. In such a constitution, a main nonopole element 19 is obtained. The base end of the element 12 is connected to a printed circuit board and also grounded with its tip part serving as a free end. Thus, an auxiliary pole element 20 is obtained. |
