For antennas for outdoor applications, different shapes of sealing rings (silicone rubber materials) are generally used for sealing. Generally, an O-shaped sealing ring is adopted, the sealing is realized by utilizing the compression elastic deformation of silicon rubber at the bottom of the O-shaped sealing ring after the antenna is assembled, but the sealing effect of the O-shaped sealing ring is related to the sizes of the sealing ring and the antenna sealing groove in the structural design of the antenna, and the silicone ring is easy to age under the influence of external factors such as sunshine, rain and the like along with the passing of the use environment and time, so that the waterproof effect is further influenced.

The built-in antenna can shield signals, antenna signals can not penetrate through the metal shell, the external antenna is mostly used for a wireless instrument of the metal shell at present, the external antenna is a small short rod antenna which is mostly used at present, the small short rod antenna is installed on the metal shell (an opening is formed in the metal shell) through threads (SMA joints), a signal is led out from the inside of the shell to the outside of the shell through a feeder inside the shell, and then the signal is connected with the small short rod antenna through a thread with a radio frequency patch cord (an SMA external thread female needle).

Such external antennas have several disadvantages:

1. the small short rod antenna is easy to lose, and is screwed together through threads, so that the small short rod antenna is convenient to detach, and once the small short rod antenna is lost, the instrument and the meter lose signals and cannot transmit data.

2. The antenna is not waterproof, the metal part of the antenna is easy to rust, water enters the inside of the instrument for a long time, and the rust can also affect signals.

3. The impact may cause the antenna to deform or directly knock the antenna apart.

Therefore, a cylindrical external waterproof antenna with good firmness is needed.
