PURPOSE:To enable the adjustment of azimuth of antenna and directional angle with a simple handle operation, by adjusting the azimuth and directional angle of the directivity of the antenna with common adjusting mechanism. CONSTITUTION:The azimuth and directional angle of the antenna 11 is supported in rotary free to the base 14 with the sypport mechanism 13, and rod 15 of male screw is unifiedly provided on the console 12 provided at the back of the antenna 11, and the female screw link 16 forming female screw at the inner circumference of the screw rod 15 is higned. The one end of the link 16 is lined to the lever 19 with the pin 18, the lever 19 is extended to opposite direction of the antenna 11, it is linked with the adjusting axis 20 with the pin 21, the adjusting axis 20 is fitted at the opposing side of the support mechanism 13 of the base stand 14 so that it can be turned, and the handle 22 is fexed to this adjusting axis. Further, the screw rod 19 is moved with the revolution of the handle 22, it is changed in spiral shape for the directional angle of the antenna 11 by moving the screw rod 15, and at the process, adjustment is made to the position is combination of the desired azimuth and directional angle. |
