The portable antenna device according to claim 1, wherein the foldable arm and the foldable arm are folded and housed in the support column. 5.   When the lever is slid downward along the side surface of the support column, the side surface of the folding arm that is deployed in the horizontal direction is pressed against the upper end surface of the support column, whereby the folding arm Is folded upward, and the folding arm is folded upward, so that the folding antenna element that has been deployed in the vertical direction perpendicular to the folding arm is folded downward by the hinge mechanism. The portable antenna apparatus according to claim 5, wherein   A method for deploying and storing a portable antenna device in a portable antenna device having a structure in which folding antenna elements supported by the tip of a folding arm radially deployed around a support column are arranged on substantially the same circumference. In the folded state, the foldable antenna element and the foldable arm are housed in the column, and when unfolded, the spring structure provided at the bottom of the column and the foldable antenna element are provided. The folding mechanism pushes up the folding arm to the upper part of the column, and then expands the folding arm in the horizontal direction from the upper part of the column to the outside, and further expands the folding type in the horizontal direction. A portable device characterized in that the folding antenna element is deployed in a direction orthogonal to the folding arm at the tip of the arm. Antenna equipment development and storage method.   As the hinge mechanism, a weight is attached to the tip of the folding antenna element, and the folding arm is moved from the upper part of the support column to the outside by the weight attached to the tip of the folding antenna element. The folding arm is deployed in a horizontal direction when exposed, and the folding antenna element is deployed in a direction orthogonal to the folding arm when the folding arm is deployed in a horizontal direction. The method of deploying and storing the portable antenna device according to claim 7.   By operating a lock mechanism for locking the spring structure provided in the bottom portion of the support in a compressed state, the compression state of the spring structure is released, and the folding type is released by the elastic force of the spring structure. The method of developing and storing a portable antenna device according to claim 7 or 8, wherein the arm is pushed up to the upper part of the support column.   When the block is exposed to the outside of the upper part of the column, the end is integrated into the block for integrating the end opposite to the tip of each of the plurality of folding arms. 10. The method of deploying and storing a portable antenna device according to claim 7, further comprising a block hinge mechanism for deploying the folding arm in a horizontal direction.   A lever attached to a block for integrating the ends on the side opposite to the tip of each of the plurality of folding arms, in a state in which it can be slid in the vertical direction along the side of the column. The spring structure is compressed by sliding downward along the side surface of the support column, and the folding antenna element and the folding arm are folded and stored in the support column. A method for deploying and storing a portable antenna device according to any one of claims 7 to 9.   When the lever is slid downward along the side surface of the support column, the side surface of the folding arm that is deployed in the horizontal direction is pressed against the upper end surface of the support column, whereby the folding arm Is folded upward, and the folding arm is folded upward, so that the folding antenna element that has been deployed in the vertical direction perpendicular to the folding arm is folded downward by the hinge mechanism. The method of deploying and storing a portable antenna device according to claim 11, wherein
