This invention relates to the field of antenna protection technology, and more particularly to an easy-to-install antenna protective cover. It includes: a base with a rubber pad embedded in its lower part; a protective shell rotatably connected to the base; symmetrically distributed first ventilation openings on the lower part of the protective shell; a guide rod fixed inside the protective shell; and symmetrically distributed first and second baffles slidably connected to the guide rod; a winding frame rotatably connected inside the protective shell; and a winding wheel located below the winding frame. Connecting ropes are provided between the first baffles and the winding frame, and between the second baffle and the winding wheel. This invention, by adjusting the positions of the first and second baffles, allows the gas inside the protective shell to exchange with the outside environment when the external wind speed is low. This allows the flowing gas to carry away the heat generated by the antenna, ensuring the normal operation of the antenna.

The application relates to an antenna networking device, wherein a lateral reflecting plate of one multi-frequency antenna is arranged in parallel with a forward reflecting plate of another multi-frequency antenna, that is, lateral radiation units on the lateral reflecting plate of one multi-frequency antenna are networked with forward radiation units on the forward reflecting plate of another multi-frequency antenna, super multi-frequency networking is realized, that is, multiple radiation units of one operator can be arranged on different multi-frequency antennas, the height size of the antenna networking device is reduced, aperture coupling is reduced, and the antenna performance is improved; in addition, the lateral reflecting plate and the forward reflecting plate are arranged at an acute angle, and when multiple multi-frequency antennas are arranged in sequence and at intervals around the circumference of a site, the overall size is reduced, the wind load is reduced, the antennas can be arranged in a compact space, the requirements of multiple operators for antenna co-construction and sharing are met, and the construction, operation and maintenance costs are greatly reduced.

This application relates to the field of communication technologies, and provides an antenna, an antenna feeder system, and a base station, to provide an antenna that can balance a beamforming capability and safety. The antenna includes a first antenna array and a second antenna array. The first antenna array and the second antenna array can rotate relative to each other. Therefore, the antenna provided in this application can balance the beamforming capability and safety in different wind force conditions by reducing an antenna surface area of the antenna.
