PROBLEM TO BE SOLVED: To accurately set an elevation angle for every predetermined angle without increasing the size of fittings. SOLUTION: The tilt fittings for an antenna include: adjustment part fittings 2 which support an antenna 1 at one position out of two upper and lower parts, and on which a plurality of angle setting bolt holes 21a-21r are formed on a degree basis for mounting the antenna 1 by adjusting the elevation angle thereof by one degree of a predetermined angle for each time by being prevented from overlapping one another; rotating part fittings 3 which rotatably support the antenna 1 at the other position out of the two upper and lower parts of the antenna 1, and are formed with a connection bolt hole 31a; and two base fittings 4 respectively mounted at two upper and lower parts of a post, and formed with angle adjusting bolts holes 41a-41e at positions meeting the plurality of angle setting bolt holes 21a-21r formed on the adjustment part fittings 2 and the connection bolt hole 31a formed on the rotating part fittings 3 when mounting the antenna 1 to the adjustment part fittings 2 and the rotating part fittings 3 by adjusting the elevation angle thereof by one degree of a predetermined angle for each time.
