12 Band High Power Mobile Phone signal blocker for GPS, WiFi & LoJack
The P-US-12-7 is a 12-band handheld cellular phone signal Blocker designed for precise, multi-band signal control in dynamic environments. Built for users who need reliable mobile interference, it combines a backpack-style; Form factor with stable performance across cellular, WiFi, and GPS frequencies—without relying on excessive noise output.
This unit features factory-calibrated frequency settings, eliminating the need for manual tuning on-site. Unlike typical Jamming equipment that gradually drift and lose effectiveness, the P-US-12-7 maintains long-term frequency stability, ensuring consistent blocking performance even after extended operation.
Each RF channel is equipped with independent filtering, allowing multiple bands to run simultaneously without internal signal cancellation. This architecture ensures clean and efficient output, something most standard equipment fail to achieve. Additionally, its optimized internal structure reduces RF reflection loss, improving real output efficiency by 12%–18% compared to conventional designs.
Thermal performance is another key advantage. The battery and mainboard are physically separated and build-in Smart Cooling Fans to prevent heat buildup, enabling continuous operation without power reduction or overheating. The system also remains effective against frequency-hopping signals, maintaining stable interference coverage.
