Introducing the A18-16A: High-Performance 18-Band Portable Signal Jammer
The A18-16A redefines portable signal jamming with its innovative 16-antenna configuration, engineered to support 18 frequency bands without interference. This professional-grade device ensures complete communication silence by blocking all modern signals, including 5G/4G/3G/2G, dual-band WiFi, GPS (L1 to L5), LoJack, and critical RF frequencies like 315MHz and 433MHz.
Key Features & Advantages:
18 Bands, 16 Antennas: Dual-band antennas on channels 12/13 and 15/16 eliminate mutual interference for optimized performance.
High 18W Output: 1W per band ensures reliable jamming across a 2-25 meter radius, adapting to local signal conditions.
Robust Cooling System: Three internal cooling fans and an enlarged heatsink maintain stable operation.
Precision Control: Individual DIP switches allow selective band activation without disrupting other frequencies.
Long-Lasting Power: A built-in 12000mAh battery provides 120-150 minutes of use, with real-time monitoring via an LCD display (capacity %, voltage, and current).
