The antenna includes an antenna body disposed on one side of a support pole and a mounting part for fixing the antenna body to the support pole. This wind-resistant 5G antenna with a mechanical stabilizer effectively solves the problem in the prior art where installing directional antennas requires two people working together—one to fix the antenna support and the other to support the antenna and provide temporary physical support to prevent it from tilting and collapsing—or using a support frame or steel cable to connect and fix the antenna to a nearby stable object.

If the operator is not stable or is not focused, the antenna's center of gravity may shift, causing it to tilt outwards or even fall, resulting in personal injury or equipment damage.
