PROBLEM TO BE SOLVED: To solve the problem that the beauty of the interior of a room is damaged because the distance between an antenna and a wall face increases in the case that a structure is provided to the antenna to allow an angle in the elevating angle direction to be regulated. SOLUTION: A spacer mount section 4 having a key groove 5 is provided to a side face section 3a of a swollen section 3 apart from the gravity center of an antenna body 1, a spacer 6 is mounted to the spacer mount section 4 by removably engaging a key section 9 with the key groove 5, an arm section 12 of an antenna mount metallic fixture 10 is in slide contact with a slide face 8 of a spacer 6, a mount bolt 15 is screwed with a thread hole section 7 of the spacer 6 via a hole section 14, a turning center Q of the antenna body 1 is set on an axial line of the mount bolt 15, and frictional force is produced between the slide face 8 and the arm section 12 through the tightening of the mount bolt 15 so as to support the antenna body 1 by the frictional force.
