T-20Pro High-performance stationary network blocker 155W

155W total output is distributed across 20 antenna channels, forming a multi-layer RF jamming structure. Each band operates independently, keeping signal handling stable under mixed-frequency environments. This is the T-20 Pro ( The upgraded version of T-N18P).

The coverage range is 20–80 meters, though the exact distance varies depending on local signal density and installation conditions. We have also performed tests in open, unobstructed areas, this jammer delivers genuine, stable performance with a range of up to 80 meters.

Quick tips: It is not recommended to use this product in areas with extremely strong signals, such as near base stations or cell towers, any jammers will not work effectively in such an environment. Please do not be misled by other sellers.

Designed as a stationary desktop unit, this high power jamming device features an aluminum alloy heat-dissipating base with a large surface area of ​​aluminum cooling fins. Combined with three multi-axial fans that generate a powerful, directed airflow, it rapidly dissipates heat from internal core components, ensuring stability during high-load operation. Consequently, you need not worry about performance degradation due to heat.

The phone blocker integrates a rotary adjustment interface, allowing for manual output adjustment without the need for external configuration tools. Furthermore, each antenna channel is equipped with an independent indicator light, allowing you to directly view the operating status on the device, reducing the need for external monitoring.

You might also notice that it comes with a remote control—isn't that convenient?

Supports two power input modes:

• Standard 220V AC power (wall outlet)
• 12V external DC input (vehicle or portable power source)
