At what temperature does the signal jammer work?

Signal jammers are electronic devices designed to operate in certain outdoor conditions, and ambient temperature is one of them. You'll see that most jammers have strictly set temperatures, and they can work just fine in them. If the temperature is below zero or above +50 degrees Celsius, you will never know what will happen, especially if the jammer does not have a cooling fan.
There are still a few exceptions to this rule. The high-temperature Cell Phone Jammer's design enables the military using it to withstand the harsh weather around the world and achieve the necessary interference effects with reliable and stable jamming equipment. The temperature range of this jammer is much wider than that of ordinary jammers.
As you can see, for any type of jammer, temperatures of 0°C to +50°C are normal. However, there are some exceptions to this rule, and you can take advantage of them!
