Import 300w High Power Vhf Uhf Nmt Cdma Single Jammer — Buy in Bulk from Supplier in China

Jammer Group produces a 300W high-power RF jamming device targeting VHF, UHF, NMT, and CDMA frequency bands for security and communications control applications. The unit delivers 300 watts of output power across multiple bands from a single transmitter architecture, rather than modular band-stitched assemblies. The enclosure carries waterproof and shockproof ratings for field deployment in variable terrain and weather conditions. Physical dimensions, weight, and antenna configuration are not stated in the source data and require direct supplier confirmation. The compact form factor referenced in source materials suggests transportability for rapid deployment scenarios, though exact carry dimensions and power source requirements remain unspecified.

The VHF band typically spans 30-300MHz, UHF 300MHz-3GHz, NMT (Nordic Mobile Telephone) operates at 450MHz and 900MHz ranges, and CDMA cellular occupies 800-1900MHz depending on regional allocation. Effective jamming radius depends on output power, antenna gain, terrain, and target receiver sensitivity, typically calculated using the free-space path loss equation with margin for clutter. The 300W rating suggests substantial coverage area in open conditions, though actual effective radius requires field measurement. The waterproof and shockproof construction implies gasket-sealed enclosure with conformal-coated electronics and shock-mounted RF power amplifiers, standard practice for militarised communications equipment. Thermal management for continuous 300W output demands substantial heatsinking or forced-air cooling, details of which are absent from the source description.

Primary users include security services, military communications units, and event management organisations requiring electromagnetic spectrum denial or controlled access. The device suits perimeter establishment, convoy protection, and venue signal management where unauthorised transmissions present operational risk. Buyers must verify frequency band legality in their jurisdiction, as RF jamming equipment faces strict regulatory controls or outright prohibition in many territories. Import licences, end-user certificates, and frequency coordination agreements may be mandatory depending on destination country. The supplier's location in Shenzhen, Guangdong Province, places manufacturing within China's principal electronics manufacturing cluster with established component supply chains for RF power devices.

Jammer Group maintains its address at Fuhuaraod, Shenzhen, 518000, Guangdong Province, China. The supplier holds imported-tier and harbour-tier classifications in marketplace records, indicating profile data sourced from external verification rather than direct platform engagement. The response rate registers 0.00 percent with zero average response hours, suggesting limited active inquiry management through monitored channels. No establishment date, employee count, factory certification, or quality management accreditation appears in the available profile.

The company's product positioning centres on high-power RF jamming equipment for security and military end users. The Shenzhen location provides access to RF component manufacturing, printed circuit board fabrication, and antenna production within the Pearl River Delta electronics ecosystem. Buyers should note that no export licence numbers, FCC or CE compliance documentation, or military specification certifications are visible in the source data. Direct engagement with the supplier is necessary to obtain technical documentation, regulatory compliance statements, and end-user verification protocols before purchase commitment.
