Lightweight Handheld Signal Jammer for 2G 3G 4G 5G WiFi GPS and UHF VHF Frequencies

This high-performance portable wireless signal jammer is engineered for reliable signal blocking across multiple frequency bands. With a compact design measuring 132×80×41mm (excluding antennas) and weighing approximately 0.8kg, it offers exceptional portability for on-the-go use. The device incorporates 8 omnidirectional antennas, enabling comprehensive jamming of signals including 2G, 3G, 4G, 5G, LTE, GPS L1-L5, WiFi 2.4G/5G, Bluetooth, UHF, VHF, and LoJack 315/433 MHz.

Equipped with a robust 4W total output power (0.5W per band), the jammer delivers an effective blocking radius of 2 to 20 meters, adaptable to local signal strength conditions. Its intelligent DIP switch allows users to selectively activate or deactivate specific frequency bands without disrupting others, providing flexible control over jamming operations. The built-in 7.4V 4700mAh lithium battery supports continuous operation for approximately 90 minutes, with recharge capability via included AC adapter (110-240V) or car charger (DC12V).

The cooling system features a high-efficiency aluminum alloy radiator and integrated cooling fan, ensuring stable performance during extended use. This jammer is ideal for maintaining silence and confidentiality in diverse environments such as meeting rooms, conference centers, museums, theaters, classrooms, banks, and vehicles. For specialized locations like hospitals or gas stations, preliminary field testing is recommended to prevent interference with sensitive equipment.

Customization services are available for specific frequency requirements, including but not limited to 2G/3G/4G/5G, LoJack 173MHz, VHF, UHF, walkie-talkie bands, and drone frequencies. OEM silkscreen options support brand personalization for bulk orders.
