Description

Ultra 12 ā€“ 120W, 120m, 12 Antennas Jammer

Ultra 12 is a Ā new generation desktop jammer designed to deliver full-spectrum protection with unmatched stability. With 120W total output power and 12 high-gain antennas, Ultra 12 ensures strong coverage against a wide range of signals ā€“ from traditional 2G and 3G bands to modern 4G LTE, 5G, GPS, Wi-Fi, and Lojack.

Its 120-meter effective range makes it an excellent choice for large halls, corporate spaces, cultural institutions, and secure facilities. Unlike compact models, the Ultra 12 is built for non-stop 24/7 operation, supported by an advanced cooling system that keeps performance consistent even during intensive use.

Whether itā€™s about securing confidential meetings, preserving silence in cultural venues, or protecting sensitive areas from unwanted signals, Ultra 12 adapts to multiple real-world scenarios with four frequency configurations (A, B, C, D) to match different environments.

What is LoJack?

LoJack is a vehicle tracking solution used by security teams and law enforcement to recover stolen cars. It functions by transmitting a radio frequency signal from a concealed unit inside the vehicle, which can be traced with specialized receivers.

The Ultra 12 jammer is engineered with extended multi-band coverage and includes a channel dedicated to the LoJack spectrum. By neutralizing this frequency, it blocks the communication between the transmitter and tracking receivers. This makes the Ultra 12 effective for signal research, controlled privacy trials, and authorized demonstrations, where analyzing interference and security performance is essential.

Applications:

Ultra 12 is ideal for:

  • Boardrooms & negotiation spaces ā€“ protect private discussions from leaks.
  • Concert halls & theaters ā€“ preserve atmosphere without interruptions.
  • Museums & galleries ā€“ keep cultural spaces distraction-free.
  • Worship places ā€“ ensure silence during ceremonies.
  • Secure facilities ā€“ block tracking, spying, and unauthorized connections.
