Vodasafe 8 Antenna Stationary Jammer
In high-security environments where confidential wireless communication must be fully restricted, a high-power stationary signal jammer is an indispensable security device. Today we introduce the flagship security equipment from SZ Vodasafe: the 150W stationary 8-antennas jammer, a multi-frequency signal blocker engineered to neutralize cell phones, Wi-Fi, GPS, Bluetooth, VHF, and UHF signals within a controllable 50 to 150-meter radiusVodasafe. Unlike low-power portable jammers limited to small rooms, this fixed high-output unit delivers stable, round-the-clock jamming performance for large indoor and semi-open spaces, making it a top pick for correctional facilities, confidential meeting centers, military bases, and exam venues worldwide.
Core Technical Advantages of Vodasafe 150W 8-Antenna Stationary Jammer
150W Total High Power & Independent 8-Band Modular Design
Equipped with eight separate RF modules and matched high-gain omnidirectional antennas, this jammer boasts a total transmitting power of 150W, evenly distributed across all target frequency bands. Each antenna channel features an independent power switch, allowing operators to turn on or shut down specific frequency bands on demand without disrupting other jamming channels. This modular design eliminates unnecessary signal interference to non-target frequency ranges and optimizes power consumption for long-term continuous operation.
High-Gain Antennas & Adjustable 50–150 Meters Jamming Coverage
Fitted with professional high-gain external omnidirectional antennas, the device creates a uniform shielding zone ranging from 50 to 150 meters. The actual coverage radius adjusts based on surrounding signal strength: in areas with weak base station signals, the maximum 150-meter shielding range can be fully achieved, while dense signal environments maintain reliable 50-meter full coverage. The all-directional antenna layout ensures no signal blind spots in the protected area, completely cutting off 2G/3G/4G/5G cellular data, Wi-Fi 2.4G/5.8G, GPS positioning, Bluetooth short-range transmission, and VHF/UHF walkie-talkie signalsVodasafe.
24/7 Uninterrupted Operation with Efficient Heat Dissipation
Built with thickened aluminum alloy heat sinks and multiple built-in temperature-controlled cooling fans, the Vodasafe stationary jammer solves the overheating pain point of high-power jamming devices. Even under non-stop 24-hour daily operation, the internal temperature stays within a safe range, avoiding performance attenuation or hardware burnout caused by long-time high-load work. The universal 100–240V AC power supply supports global commercial power grids, suitable for fixed installation in various countries and regions.
Full-Spectrum Signal Blocking Compatibility
This 8-antenna jammer covers all mainstream civilian and security wireless frequencies:
After powering on, all wireless devices inside the shielding zone will lose calling, internet access, positioning, and intercom functions, thoroughly preventing information leakage, cheating, and unauthorized remote communication.
Main Legitimate Application Scenarios
Prisons & Detention Centers: Block smuggled cell phones to stop illegal inmate communication and contraband coordination.
Government & Corporate Confidential Meeting Rooms: Prevent hidden recording devices, wireless cameras, and signal leakage of sensitive meeting content.
Examination Halls & Training Centers: Eliminate cheating via mobile phones, Bluetooth earpieces, and GPS communication tools.
Military & Border Security Zones: Shield VHF/UHF walkie-talkies and positioning signals to protect confidential operations.
Museums & High-Security Archives: Avoid unauthorized wireless transmission of cultural relic and confidential document data.
Installation & Usage Notes
As a stationary fixed jammer, the unit supports wall-mounted or desktop fixed installation for permanent security layout. Users need only match the included high-gain antennas to corresponding RF ports, connect the AC power adapter, and toggle band switches to activate targeted jamming. Important reminder: This device shall only be deployed in authorized, closed security areas in compliance with local radio communication regulations; unauthorized use in public spaces that disrupt public communication networks is prohibited.
For enterprises and institutions seeking wide-range, stable, full-band wireless signal shielding, the Vodasafe 150W stationary 8-antennas jammer balances ultra-high output power, adjustable coverage, 24-hour stable operation, and flexible frequency control. Its integrated high-gain antenna system and multi-channel modular structure make it a cost-effective long-term security solution compared to assembling multiple low-power small jammers. If you require customized frequency bands or larger-area shielding schemes, SZ Vodasafe also provides OEM and frequency band modification services tailored to unique security demands.
