Problems solved by technology
[0002] Due to the high requirements on the amplitude and phase consistency of the short-wave vertical segmented load antenna array, lightning rods cannot be installed nearby, so the probability of being directly struck by lightning is very high, and the loader is easily damaged
Commonly used load sensors are composed of ordinary resistors and inductors, which are easily damaged by lightning and electromagnetic pulse shocks
After the loader is damaged, it is very difficult to erect and maintain the vertical segmented load antenna array. It is difficult to overhaul it after each lightning strike, but the lightning strike may damage part of the loader, making the antenna array in an abnormal state. working status
According to the traditional lightning protection concept, lightning protection must have a ground wire, and the lightning current is discharged through the ground wire, but for the antenna, if the ground wire is connected, the original characteristics of the antenna will be changed, which is not allowed

The invention discloses a short wave antenna lightening protection sensor. The short wave antenna lightening protection sensor comprises an inductor (11), a decoupling device (12), a resistor (13) and a discharging device (14), wherein one end of the inductor (11) is connected with a first leading wire (1), the other end of the inductor (11) is connected with a second leading wire (2) and one end of the decoupling device (12), the other end of the decoupling device (12) is connected with one end of the resistor (13), the other end of the resistor (13) is connected with a third leading wire (3), and two ends of the discharging device (14) are respectively connected with the first leading wire (1) and the third leading wire (3). According to the short wave antenna lightening protection sensor, relatively strong lightning protection and electromagnetic pulse impact prevention capabilities are realized, the sensor is not substantially different from generally-used sensors in reactance characteristics, and influence on performance of an antenna is avoided.
