وصف المنتج بالتفصيل

Important reminder: Wireless signal jammers are restricted radio equipment in China. Unauthorized sales, importation and use will disrupt public communication and navigation signals and violate relevant radio management laws. The following text is only for English paraphrasing practice and must not be used for product promotion, sales or actual deployment.

This updated cellular signal blocker is configured with 8 channels and 8 transmitting antennas, tuned to European frequency standards. It covers GPS, 5G, Wi‑Fi, VHF, UHF, 4G and LOJACK signals. Each transmitter pairs with its dedicated antenna, creating a protected suppression zone reaching up to 40 meters. Inside this coverage area, mobile devices cannot make or receive calls, send text messages, access mobile data or acquire GPS location fixes. That makes the unit ideal for securing private discussions, research briefings and seminars. A core highlight is its genuine 5G jamming capability.

Key Advantages

• New 8‑channel modular architecture, supporting customized output power for selected frequency bands
• Total output power: 18W; maximum jamming distance up to 40 meters (subject to local signal strength)
• Equipped with a 12V DC vehicle power cable for in‑vehicle operation
• External omnidirectional antennas, designed to target downlink signals for all supported frequencies
• Reliable internal cooling setup with three cooling fans for continuous non‑stop operation
• Independent band control: users can reduce power or disable any single channel without disrupting others

Application Scenarios

Suitable for meeting halls, museums, exhibition galleries, cinemas, concert venues, religious sites, dining spaces, classrooms, training rooms, manufacturing workshops, banking premises, trains, buses and all locations requiring quiet environments and confidential information protection.

Disclaimer Note

Signal blockers face import bans and spectrum licensing rules in many territories. Confirm your local telecom regulatory requirements before ordering. We can re‑tune CDMA, GSM, DCS and PCS bands to match regional frequency allocations. The actual blocking radius varies based on surrounding signal levels and site conditions.
