Abstract

The invention discloses a columnar antenna feeder lightning arrester, and aims to mainly solve the problems that the existing T-shaped quarter wavelength antenna feeder lightning arrester occupies a large space and is incompact in structure and insufficient in bandwidth and overcome the defects that the general columnar quarter wavelength lightning arrester is high in insertion loss and the communication signal transmission is easy to affect. The columnar antenna feeder lightning arrester is characterized in that a connection piece is arranged between a first shell and a second shell; a columnar inner cavity and an annular inner cavity are formed in the connection piece; the columnar inner cavity is communicated with the inner cavities of the first shell and the second shell; an annular inner core is arranged in the annular cavity; an isolating wall for isolating the columnar inner cavity from the annular cavity is arranged in the connection piece; the annular inner core penetrates through a through hole in the isolating wall and is connected with a main coaxial core; therefore, the columnar antenna feeder lightning arrester occupies a small space, and the mounting is not limited; a discharging channel is approximately closed, and a discharging process is low in influence on a communication signal; the insertion loss is low.

Description

Technical field [0001] The lightning arrester of the present invention is mainly applied to the field of microwave communication, and particularly relates to a cylindrical antenna feeder lightning arrester. Background technique [0002] The antenna-feeder lightning arrester is an indispensable original for microwave communication. It is connected to the coaxial cable between the transmitting antenna or the receiving antenna and the equipment in the equipment room to block lightning surge pulses from invading the equipment room, thereby avoiding damage to the communication equipment. This kind of lightning arrester must be able to filter out lightning on the one hand, and at the same time it must not have much influence on the transmitted communication signal. The T-shaped antenna feeder lightning arrester is a lightning arrester designed according to the communication signal spectrum and the spectrum distribution of lightning pulses. The frequency spectrum of lightning pulses is...
