3G/4G Cell Phone Jammer with 5 Powerful Antenna
The 3G/4G Cell Phone Jammer with 5 Powerful Antennas is a signal-blocking device designed to disrupt mobile communications across multiple frequency bands. It outputs a total of 12W, distributed across five high-gain antennas to cover GSM850 (850-894 MHz), GSM1900 (1930-1990 MHz), 3G (2100-2170 MHz), and 4G LTE (725-770 MHz and 2345-2400 MHz). The unit is engineered for indoor use in controlled environments, with a compact form factor for discrete installation.
The jammer’s construction includes a metal chassis for heat dissipation and overheat protection circuitry, both standard for devices in this category. The antennas are typically omnidirectional with 5-10 dBi gain, though the listing does not specify exact models. Effective jamming range varies by environment but is usually 10-40 metres in open spaces for a 12W unit, depending on signal strength and obstacles.
This model is suited for hospitality (hotels, conference centres), corporate security, and event management, where unauthorised mobile use must be prevented. The listing does not confirm MOQ or pricing, but bulk packaging is implied. Buyers should verify legal compliance for jamming devices in their jurisdiction, as regulations differ widely by country.

Jinyatong Technology (China) Co., Ltd. is located at Niulanqian Building, Minzhi Ave., Longhua, Bao’an District, Shenzhen, Guangdong, a key area for security electronics manufacturing. The company holds an imported supplier tier and a harbor trust tier, though its response rate and average response time are currently listed as zero, indicating limited tracked engagement.
The supplier focuses on signal jamming and security equipment, with the listing highlighting its 5-antenna jammer as a flagship product. No certifications are confirmed in the profile, though the source description mentions ISO compliance.

Sourcing 3G/4G Cell Phone Jammer with 5 Powerful Antenna from Jinyatong Technology (China) Co., Ltd. - China Import Guide
Before ordering, confirm the legality of using cell phone jammers in your country, as many jurisdictions restrict or ban their use outside authorised facilities. Request the supplier’s compliance documentation for local regulations, including any required permits or certifications for import and operation.
Discuss shipping terms, as jamming devices may be classified as restricted electronics. Clarify Incoterms (e.g., FOB Shenzhen) and whether the supplier handles export controls or customs documentation. Lead times may vary due to regulatory checks, so plan accordingly.
For quality checks, test the jammer’s effectiveness across all claimed frequency bands using a spectrum analyser or signal meter. Verify the overheat protection by running the device at maximum power for extended periods. Request a demonstration of the antennas’ coverage pattern to ensure no blind spots in your intended environment.
