As the most popular handheld jammer available, this device is small and easy to transport. It can block 8 frequencies and has a very wide interference range. There is a separate frequency control switch to turn your desired frequency on or off as required and comes with a car charger so that you can use it while traveling.

This device has a well-developed heat dissipation system for extended periods of continuous operation. Its housing is made of thermally material for effective heat dissipation.

In general, the larger the jammer range and the stronger the interference performance, the heavier the device is and the more awkward it is to carry around! However, this device is exceptional. This 8-band handheld jammer not only offers a great jamming performance and can block up to 40 meters, but also has good mobility, with the device measuring just 130mm*80mmx38mm and weighing only 600g.

The color used for this device is Popular Black, which helps prevent it from being easily smeared. The performance is comparable with that of a desktop jamming device in every way. This product is a must-have for any serious radio amateur.
