When testing the effect of the signal scrambler to interfere with the remote control, what should be paid attention to?
Due to the increasingly widespread application of consumer rotary-wing drones, many sensitive locations that are not allowed to fly, such as prisons, airports, government agencies, high-level scientific research sites, border areas, and military bases, often have unknown hobbies. Or someone with ulterior motives is taking aerial photography. For drone flight in this scenario, signal scrambler are often used to interfere with the remote control signal of the drone for defense.
In addition, signal jammers are also used when military police respond to terrorists' remote-controlled bombs and other dangerous goods controlled by remote-controlled signals.
But it has to be mentioned that when customers buy and use signal jammers device, it is recommended to test the interference effect of the remote control signal of the remote control in advance, and the test should pay attention to the following matters:
1. Test after the signal blocker is connected correctly and the power on is normal. It is necessary to maintain a certain distance between the remote control and the remote control object. If the distance between the remote control and the remote control object is too close, for example, the distance between the two is one or two meters. Or within a few meters, which is unrealistic in practical applications, and the distance is too close to require a remote control. Therefore, when testing the real interference effect of the signal scrambler, it is necessary to keep the distance between the two at a distance of more than ten meters or longer, which is more in line with the actual combat situation.
2. The remote control is a point-frequency transmitter. Although the power of the point-frequency is small, the bandwidth is narrow. Therefore, at a very close distance, it may have stronger anti-interference performance. , the interference effect of the signal scrambler is very obvious. The farther the two are, the more obvious the interference effect of the signal jammer will be.
3. There are many operating frequency bands of the remote control, such as 27MHz, 135MHz, 433MHz, etc. In actual use, please make sure that all the antennas of all low-frequency modules on the signal jammer are connected reliably, and all the boots work normally.
