SECURADIO Advanced Radio Frequency Shielding System
Hertz-precision RF shielding for critical institutions — block unauthorized radio communication without disrupting legitimate signals.
SECURADIO is a high-precision radio frequency shielding system developed by Alfasis for critical institutions requiring protection against unauthorized radio communication. Operating across the 5 MHz to 12 MHz frequency range with up to 35W RF output, it blocks specific broadcast channels at 1 Hz resolution — suppressing illegal or threat-carrying transmissions while leaving authorized frequencies fully operational. Its compact desktop form factor and indoor-deployable antenna eliminate the need for exposed external installations.
Разработано для современных оборонных и охранных сред.
SECURADIO addresses a specific and underserved threat: unauthorized handheld radio use within critical institutions, and external RF transmissions carrying terrorist propaganda or covert messaging. Unlike broadband jammers, SECURADIO targets only the required frequency range with minimum bandwidth, preserving legitimate communications and maximizing energy efficiency. UPS and battery backup guarantee uninterrupted operation during power outages, while optional FM band blocking and remote monitoring extend its capability to a full-spectrum communication security platform.
Основные возможности и оперативные преимущества.
1 Hz Frequency Precision
Capable of blocking a range as narrow as a single Hertz — enabling surgical suppression of specific threat frequencies without affecting adjacent channels.
Minimum Bandwidth Blocking
Blocks only the required bandwidth for each target frequency, preventing unnecessary interference with neighboring channels and maximizing the usability of the RF spectrum.
Indoor Antenna Deployment
Short-range blocking capability eliminates the need for exposed outdoor antenna installations. The device and antenna can be positioned inside the building or on the rooftop.
UPS & Battery Backup Operation
220V AC operation with integrated UPS and battery support guarantees continuous shielding even during power outages — critical for facilities that cannot tolerate gaps in RF protection.
Adjustable Frequency Selection
Operators can manually configure specific frequency ranges to block, ensuring only targeted channels are suppressed while all other communications remain unaffected.
AM & FM Band Coverage
Blocks all AM radio broadcasts within specified frequencies. Optional FM band blocking extends coverage to the full broadcast radio spectrum.
Energy-Optimized RF Architecture
Optimized power consumption using only required bandwidth modulations reduces energy use while maintaining maximum shielding effectiveness.
Remote Monitoring & Control
Optional remote monitoring and control interface enables centralized management of the shielding system from a secure operator location.
