T-N8 - 8 bands Stationary 5G cell phone Jammer blocker (20W)

The T-N8 mobile signal jammer effectively blocks signals within a 30-meter radius, disrupting 8 communication standards, including 3G, 4G, 5G, Wi-Fi, and GPS. Each channel has its own antenna and power adjustment, allowing precise control over the range and intensity of signal suppression. Designed for continuous operation, the device can be powered by a 220V power source or a vehicle cigarette lighter for added flexibility.

Need Reliable Protection Against Data Leaks? Consider the T-N8 Signal Blocker!

It is easy to avoid becoming a victim of information espionage - just remember that any nearby mobile device is your potential "enemy". The solution to this problem is not difficult either. It is enough to get a device like "T-N8". This compact, plug-and-play device creates a secure, interference-free zone in areas like offices, conference rooms, or private spaces. Say goodbye to unwanted calls and messages, prevent employees from browsing the internet during work hours, and most importantly, ensure confidential conversations remain private.

Key Benefits of the "T-N8" cell phone Jammer

• Blocks GPS Tracking – This prevents attackers from tracking your location.
• Disrupts WiFi Signals – This prevents information leakage by "draining" it through wireless local networks.
• Neutralizes 4G LTE/WiMAX, 5G – Renders even high-speed communication devices ineffective
• Dual Power Options – Operates via a standard power source or a 12V car adapter, making it portable and not restricted to indoor use
• Durable in Extreme Conditions – Functions reliably in temperatures ranging from -40°C to +55°C, eliminating concerns about environmental factors
• The device can be operated without the involvement of Technical guidance, so there is no unnecessary trouble and cost. All you need to do is screw on the required antenna (1...8) and power the device.

For optimal performance, it’s recommended to place the device at a height of 1–1.8 meters and away from metal objects to avoid signal interference.

Other Silencer features:

• Wide Coverage Area – The T-N8 jammer is designed to effectively neutralize mobile communications across large indoor spaces. Unlike many conventional jammers, this model boasts superior power, allowing it to block signals within a maximum radius of 30 meters. However, the actual range may vary based on proximity to cellular base stations, with optimal performance achieved when signal strength is between 60% and 75%.
• Selective Signal Suppression – Unlike standard jammers that indiscriminately block all mobile signals, the T-N8 provides targeted interference. It allows users to selectively disable specific frequency bands while keeping others operational. This makes it an ideal choice for environments where only certain devices need to be restricted—such as disabling mobile phones during confidential meetings while keeping 3G/4G/5G modems active. Furthermore, its controlled suppression prevents interference in adjacent rooms, ensuring a seamless and efficient signal management system.
• Customizable Controls – The device features eight independent adjustment knobs, each corresponding to a specific frequency range. Users can fine-tune suppression levels and enable or disable different bands as needed, providing greater flexibility and precision in signal blocking.

Each of the eight antennas has its own power regulator.

How the T-N8 Jammer Works: Simple, Efficient, and Reliable

The T-N8 desktop jammer operates using eight independent transmitters, each paired with its own antenna to generate a controlled "dead zone" for mobile communication.

The effectiveness of the jammer depends on several factors, such as physical obstructions and signal strength in the area. Its interference spreads uniformly in both horizontal and vertical directions, forming an invisible spherical shield. This ensures comprehensive protection against unauthorized communication. For instance, if placed on the second floor, the jamming effect will extend to both the first and third floors, maintaining security across multiple levels.

No interference with electronic equipment!

This device specifically suppresses the operation of mobile phones and other wireless devices, but does not in any way affect the operation of wired electronic equipment within its range: it does not interfere with computers, players, televisions, acoustics, etc.

On one of the sides of the device there is: an on/off button and a power connector

Robust Metal Casing – Ensuring Durability and Protection

Designed with a sturdy metal enclosure instead of plastic, this jammer offers exceptional durability and resistance to external impacts. The metal casing also functions as an effective heat dissipator, preventing internal components from overheating. This design allows for continuous 24/7 operation without performance degradation.

Engineered for Safety

Signal jammers will not cause any harmful effects on the human body. Their electromagnetic radiation power is within the internationally permitted standards. In fact, the radiation exposure from an ordinary cell phone—held directly against the head during calls—is significantly stronger than that of the jammer, which remains at a safe distance.
