P-N21 – Professional Portable 21-Bands Signal Jammer (21 Antennas)

Multi-Frequency Interference Device with WiFi 6E, GPS L1–L5, LoRa & 5G Support

When the N-X16P no longer meets growing operational requirements, the P-N21 becomes the natural next step.

As a major performance upgrade within the P-N-Series platform, the P-N21 expands coverage into newly deployed wireless spectrum ranges including WiFi 6E, LoRa, and extended ISM frequencies such as 868 MHz and 915 MHz — bands that are increasingly used in modern communication and IoT systems.

With 21 independently operating channels, enhanced power delivery, and an improved cooling architecture, the P-N21 ranks among the most capable portable multi-band jammers in its performance class.

Key Performance Highlights

True Hardware Upgrade — Not a Cosmetic Refresh

The P-N21 is engineered as a genuine technical evolution:

• 21 active frequency bands (upgraded from earlier 16-band designs)
• Extended coverage for modern wireless and IoT protocols
• High-capacity 7.4V / 15,000mAh battery delivering over 90 minutes of continuous operation
• Advanced thermal management system for stable long-duration output

Comprehensive Frequency Coverage for Modern Wireless Environments

The P-N21 is capable of simultaneously suppressing:

• Mobile Networks: 5G / 4G LTE / 3G / UMTS / GSM
• Wireless Connectivity: Bluetooth, WiFi 2.4G, 5G, and WiFi 6E
• Satellite Navigation: GPS L1 / L2 / L3 / L4 / L5
• IoT Communication: LoRa
• Vehicle & Radio Signals: LoJack, VHF, UHF
• RF Control Bands: 315 MHz, 433 MHz, 868 MHz, 915 MHz

The effective interference radius typically ranges from 2 to 25 meters, depending on surrounding signal strength and environmental conditions.

Independent Channel Switching for Precision Control

Each frequency band is equipped with its own dedicated DIP switch.
This allows operators to selectively enable or disable individual channels without affecting the rest of the system — providing flexible spectrum management instead of blanket signal shutdown.

Portable Design with Field-Ready Mobility

The included arm-strap carrying system allows comfortable body-mounted operation.
The reinforced nylon housing offers impact resistance and protection during mobile deployment.

This makes the P-N21 suitable for both stationary and mobile operational scenarios.

Intelligent Cooling System for Stable Performance

A large aluminum heat sink combined with three integrated cooling fans ensures consistent temperature control even during extended operating sessions or high-load conditions.

This design significantly improves long-term reliability and output stability.
