If mobile silence is golden, the T-US-T4 is your gold standard. Built like a shield and armed with four high-gain omnidirectional antennas, this wall-mounted 3G WCDMA signal blocker delivers uncompromising power to protect your space from unwanted wireless intrusion.
📡 Wide Frequency Coverage
Silencing CDMA, GSM 900, DCS/PCS, and 3G WCDMA bands, the T-US-T4 operates between 850 MHz and 2170 MHz, neutralizing devices using these signals within 30-50 meters. Whether it’s blocking disruptive phone calls in conference rooms or securing sensitive areas against data leaks, this jammer gets the job done.
💪 Power You Can Rely On
With 10W output per channel (total 40W), the T-US-T4 runs 24/7 from any standard wall socket, making it a dependable choice for offices, examination halls, correctional facilities, or private properties where network isolation is critical.
⚠️ What You Should Know Before Buying
- Weight & Size – At 20 kg and 385 × 340 × 180 mm, it’s built for fixed installation, not portability.
- Signal Legality – Check local regulations before use, as jamming devices may require specific permits in your country.
- Interference Range – Actual coverage may vary depending on building materials, interference sources, and antenna placement.
✨ Why Users Love It
“We installed the T-US-T4 in our boardroom to prevent unauthorized recordings. Since then, we’ve had zero interruptions – and complete peace of mind.” – Corporate Security Manager
💡 Pro Tip: This model is built for stationary deployment — at 20 kg, it’s not your “throw it in the backpack” kind of jammer. For those needing similar muscle at a lower cost, check out the T-US-05.
