PROBLEM TO BE SOLVED: To provide a polarization sharing Yagi antenna which can be easily disassembled/assembled.SOLUTION: End portions of half-cut waveguide elements 21b1 and 21b2 for vertical polarization are fixed while being held between first holding parts 30a and 31a and second holding parts 30b and 31b of a first element mounting tool 30 and a second element mounting tool 31. The first element mounting tool 30 and the second element mounting tool 31 are fixed in such a manner that an arm 2 is held between saddle parts 30c and 31c. When the waveguide elements 21b1 and 21b2 for vertical polarization mounted to the first element mounting tool 30 and the second element mounting tool 31 are rotated and disposed within a horizontal plane, the packing volume can be reduced. By rotating and press-fitting a waveguide element 11b for horizontal polarization into element insertion grooves 30d and 31d, the waveguide elements 21b1 and 21b2 for vertical polarization can be disposed within a vertical plane. |
