Description détaillée du produit

Important reminder: G29245 Wireless signal jammers are restricted radio equipment in China. Unauthorized sales, import and use will interfere with public communication and navigation signals and violate relevant radio management laws. The following content is only for English paraphrasing practice and must not be used for product promotion, sales or practical use.

This newly engineered all‑in‑one signal blocker comes equipped with 22 antennas, delivering robust suppression for 5G LTE, GSM, 3G and 4G LTE cellular signals. Beyond mobile networks, it is capable of disrupting Wi‑Fi 2.4G / 5GHz, GPS, LOJACK, RF 315 MHz and 433 MHz, as well as VHF, UHF two‑way radio and wireless audio headsets or microphones. As a full‑band suppression unit, it supports a maximum jamming radius of up to 40 meters.

Core Advantages

• 22‑channel full‑band layout, with adjustable output power tuned for selected frequency ranges
• Total power output reaches 45W; effective blocking distance spans up to 40 meters (subject to local signal strength)
• External omnidirectional antennas, engineered to target downlink frequencies for all supported transmit channels
• Supports 12V DC vehicle power connection for in‑car deployment
• Integrated premium cooling assembly for stable continuous non‑stop operation
• Independent channel control: users may adjust power or shut down any single band without affecting others
• Infrared remote control available for power switching from a distance of 2–5 meters

Application Scenarios

It fits meeting rooms, exhibition halls, museums, art galleries, cinemas, concert venues, religious buildings, restaurants, classrooms, training centers, factories, banks, trains, coaches and all premises requiring quietness, confidentiality and information security. For sensitive sites including hospitals and gas stations, an on‑site test is strongly recommended beforehand to avoid interference with existing medical instruments and industrial equipment.

Important Notes

1. This G29245 jammer is customized to match regional frequency standards. The destination country for purchase and actual usage must be consistent; otherwise, the device cannot work properly. Please learn about its functions before ordering.
2. Low‑power handheld blockers often deliver weak or even ineffective results against high‑power transmitters such as powerful Wi‑Fi routers and Bluetooth speakers.
3. Operation while charging is prohibited.
4. Handheld models cannot be used as desktop jamming devices.
5. Never power on the unit before all antennas are fully connected. The actual coverage range is affected by local signal intensity and surrounding environmental factors.
