20 Bands High Power Cellular Network Jammer with Remote Control

How can you ensure confidential negotiations stay private or prevent internet access during exams or employee assessments? The advanced "DJ-20T" mobile communication and network jammer is the ideal solution for these scenarios and more!

Building on the features of earlier models like the "DJ-16" and "DJ-18," the "DJ-20T" comes equipped with additional detachable antennas, making it capable of blocking a wider range of communication standards. This includes modern 5G networks, Wi-Fi, GPS, GLONASS, and internet connectivity.

User-friendly and fully automated, the "DJ-20T" requires no complicated setup. It effectively disables all data transmission devices, ensuring complete communication disruption with minimal effort.

You might be curious why the DJ-20T is priced higher than the DJ-22, despite being the same model. The reason is that the DJ-22 is a special offer product currently on sale, and its materials are not as high-quality as those used in the DJ-20T.

Benefits of this model:

• Wide coverage area (up to 50 m): Perfect for large spaces like conference halls, lecture theaters, or meeting rooms, this jamming device can effectively block signals within a 50-meter radius. However, external interference may reduce this range. While some stores claim the DJ-20T can reach up to 150 meters, experts regard this as unrealistic.
• Customizable antenna settings: Each antenna is equipped with an adjustable power regulator, allowing you to selectively block specific frequencies while leaving others unaffected. Signal strength can be fine-tuned or entirely disabled via rotary controls on the antennas.
• Advanced overheating protection: Designed for prolonged use, the signal blocker remains cool even under continuous operation. A built-in fan and a heat-dissipating housing ensure reliable performance and efficient temperature management.
• Versatile power options: The device supports power from standard wall outlets (220 V) or a 12 V connection, such as in a car. Both types of cables are included, making the jammer suitable for a variety of settings.
• Convenient remote operation: A user-friendly remote control enables discreet on/off switching, even when the device is installed in less accessible areas.

Caution: When fully activated, the jammer may disrupt the functionality of certain car alarms and automatic doors. Use the device responsibly to avoid causing inconvenience in the surrounding environment!
