［産業上の利用分野］
未発ＩＪＩＩ ｉｆ、ＨＦ 、ＶＨＦ 、ＵＨＦＨＦア
ノアンテナするもので、特にアマチュア無線の移動連用
や災害時の非常通信用に適したアンテナに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an antenna for use in unreleased IJII, HF, VHF, and UHFHF antennas, and is particularly suitable for mobile use of amateur radio and emergency communication during disasters.

使用されていない。[Prior Art] Conventionally, high-gain directional antennas such as Yagi antennas, high-gain omnidirectional collinear antennas, and the like have been used as VHF and UHF band antennas for fixed stations. However, for mobile stations, except for automatic movement, wide whip antennas are used in most cases from the viewpoint of portability, and high gain antennas are rarely used.

、これも現実には困難なことが多い。[Problems to be solved] However, it is clear that if high-gain directional antennas can be used even in mobile operations, the communication range will be wider and it will be advantageous against interference. Since the gain directional antenna is made of aluminum pipes or the like, it takes up a large volume even when disassembled, and has the disadvantage that the more elements there are, the heavier the antenna becomes. Another disadvantage is that it takes time to disassemble and assemble, which shortens the operating time at a moving location. Furthermore, supports that can support a certain amount of weight need to be brought along at the same time or procured locally, but this is often difficult in reality.
