T-N20 20 antennas High Power Desktop Signal Jammer with Remote Control (50W)

The T-N20 is not simply a continuation of the T-N16 and T-N18 — it improves on their strengths with more power, more frequency options, and better control flexibility.

With 50W total output power, a coverage capability of up to 60 meters under suitable conditions, supported frequency ranges include:

Technical Specifications of T-N20 Desktop wireless signal jammers：

Instead of treating all frequencies as one group, the network blocker includes independent adjustment knobs that allow users to fine-tune the output intensity of each frequency section instead of running every channel at maximum power.

Each antenna is clearly marked with its corresponding frequency band, making installation faster and reducing confusion during setup. From cellular communication bands to WiFi or GPS-related frequencies, every channel has its own dedicated antenna connection.

High output power creates heat, and heat management directly affects stability. The desktop jamming device combines two cooling methods:

• Milled fin-style passive cooling base
• Dual-side forced air cooling system

The aluminum fin structure increases heat dissipation efficiency, while the side cooling fans improve airflow around internal components. This combination provides a more stable operating environment during extended use.

The cellular phone jammer supports both standard 220V wall outlet power and 12V power input, allowing more installation flexibility. Users can connect the device directly to a regular AC power source or integrate it with a 12V power system depending on the application environment.

The included remote control allows users to turn the device on or off without approaching the main unit, this small detail improves convenience.
