ANTENNA DIRECTION ADJUSTING DEVICE

PROBLEM TO BE SOLVED: To easily and accuretaly adjust the direction of an antenna with simple, compact and lightweight structure by rotating an upper clamp on a stay in an azimuth angle direction and turning antenna metal fittings on an axis of elevation angle rotation in an elevation angle direction. SOLUTION: Lower clamps 12 and 13 and upper clamps 11 and 14 are coupled by bolts 15 to 17, and the stay 2 is clamped and fixed by the lower clamps 12 and 13. The antenna metal fittings 20 are attached to the antenna 1 and fixed to the upper clamp 11. The bolts 16 and 17 are unclamped, and an adjusting bolt 31 of an azimuth angle adjusting means 30 is clamped to press the part of a long hole 32 of the upper clamp 11. The upper clamps 11 and 14 rotate on the stay 2 on the lower clamps 12 and 13 and the antenna 1 is adjusted in the azimuth angle direction. An adjusting bolt 41 is clamped to press the part of an engagement hole 42 of the antenna metal fittings 20. The antenna metal fittings 20 rotate on the axis 23 of elevation angle rotation and the antenna 1 is adjusted in the elevation angle direction.
