Import 2g+3g+Remote Control Audio Jammer,Cpj-X12 — Buy in Bulk from Supplier in China

The Vodasafe CPJ-X12 is an adjustable 12-band jammer designed to block all wireless networks including cellular bands (CDMA 851-894MHz, GSM 925-960MHz, DCS 1805-1880MHz, PCS 1920-1990MHz, 3G UMTS 2110-2170MHz), GPS L1 (1575.42MHz), Lojack (173.3MHz), 433MHz, 315MHz, Wi-Fi/Bluetooth (2400-2483MHz), 4G LTE (725-770MHz), 4G WiMAX (2300-2400MHz, 2620-2690MHz), VHF (135-175MHz), and UHF (435-475MHz). Each band delivers 2.5W of output power, with adjustable settings to turn bands on or off independently. The unit operates on AC 100-240V (50/60Hz) converted to DC 12V/6A, ensuring compatibility with global power standards.

Housed in a compact chassis measuring 330mm x 238mm x 60mm and weighing 5.5kg, the CPJ-X12 features omnidirectional antennas with a minimum 2.5dBi gain per band. Typical jamming radius ranges from 2 to 50 meters at -75dBm, though this depends on local signal strength; VHF/UHF shielding radius is generally shorter than for cellular signals. Standard industry practice for such devices includes slow-start circuitry for reliability, over-temperature protection, and VSWR (Voltage Standing Wave Ratio) safeguards to prevent damage from impedance mismatches.

This jammer is used in environments requiring controlled signal suppression, such as movie theaters, hospitals, religious sites, universities, prisons, and government facilities. It is also deployed for security applications like VIP convoy protection, bomb disposal, and petrochemical industry safety. Buyers typically confirm compliance with local regulations before use, as signal jamming laws vary by jurisdiction. The CPJ-X12 is designed for commercial and institutional applications where interference with wireless communications is necessary.

Vodasafe is based in Baoan District, Shenzhen, China, a region known for its concentration of electronics and communications manufacturers.
