Description

Technical Field

[0001] This invention relates to the field of antenna technology, and more particularly to a mounting bracket for a base station antenna. Background Technology

[0002] With the development of mobile communication technology, multi-frequency and multi-port integration at the base station antenna is required to improve network capacity. Antenna structures are becoming increasingly complex, making weight and cost control the most pressing challenges. This new mounting bracket uses tubular metal bending to simplify manufacturing, reduce the number of parts, offers multiple applications, and further reduces the overall weight of the device.

[0003] The most common solution for base station antenna mounting brackets under current technology is to use thick steel plates, employ heavy-duty stamping equipment, and combine multiple sets of specialized stamping dies for forming. After bending, hot-dip galvanizing is performed to form a protective surface layer. The main components form the upper and lower corner arms with a U-shaped cross-section, and aluminum tubes are inserted at the joints to support and secure the locking points against deformation. This solution is costly and has a complex manufacturing process. The stamping and bending processes cause material damage and thickness variations in the sheet metal, and the surface also develops zinc nodules or burrs due to the hot-dip galvanizing process. The back of the antenna radome is a critical area exposed to rain and ultraviolet radiation. Under long-term exposure to harsh outdoor environments, bolts may loosen, materials may age, and the upper and lower corner arms may loosen at the connection points due to the antenna's own weight and wind forces, leading to changes in the antenna's downtilt angle, functional failure, and in severe cases, even an accident where the antenna falls.

[0004] In existing base station antenna packaging solutions, the mounting bracket is packaged separately in a box and placed at one end of the antenna packaging box. The top and bottom ends of the antenna are made of EPE or EPS foam or cardboard to form a buffer to prevent damage to the antenna from drops and impacts during transportation. However, due to the increased weight of multi-band high-gain antennas, this packaging method results in a longer packaging size. On the one hand, it leads to high logistics costs, inconvenient transportation, and significant material waste. It also fails to meet environmental protection requirements and does not provide good protection. Once the outer cardboard box experiences changes in moisture-proof and humidity-proof conditions during transportation and storage, the packaging strength drops sharply, making it impossible to deliver the product normally.

[0005] In existing outdoor installation solutions for base station antennas, the mounting bracket needs to be removed from its separate packaging box, bolted to the antenna body, and then hoisted onto a tower or rooftop mounting pole for further bolting. This process is cumbersome and inconvenient, requiring the use of binding ropes and posing safety hazards. Installation becomes even more difficult when the length of the antenna mounting pole is limited. Summary of the Invention

[0024] In one embodiment, the pole holding hoop includes a mounting fastening hole, a mounting fastening nut and a mounting fastening bolt.

[0025] The mounting fastening hole is arranged at both ends of the open pipe of the pole holding hoop.

[0026] The mounting fastening bolt passes through the mounting fastening hole and is locked with the mounting fastening bolt, so as to achieve clamping of the antenna mounting pole.

[0027] In one embodiment, the pole holding hoop is deformed by thread rotation tensioning, so as to achieve synchronous fastening of the upper support frame, the lower support frame and the antenna mounting pole.
