Product categories
Eight lines cover the usual counter-surveillance and counter-UAS build: the jammer or module itself, the antenna and feed line, the power stage and the accessories.
Cell Phone Signal Jammers
Handheld and desktop jammers with multi-band coverage for exam halls, meeting rooms, detention facilities and secure sites. Built with shielded amplifier modules, low-noise power supplies and optional network control.
View modelsRF Power Amplifier Modules
GaN and linear amplifier modules covering 100 MHz to 5.8 GHz in 10 W to 200 W classes, supplied with test data for jammer integration and custom RF systems.
View modelsDrone Jammer Modules
Band-specific counter-UAS amplifier modules for 433 MHz, 900 MHz, 1.2 GHz, 1.4 GHz, 1.5 GHz, 2.4 GHz and 5.8 GHz, ready for OEM system assembly.
View modelsDrone Jammer Systems
Handheld, backpack, desktop and high-power drone jammer systems for airports, prisons and border patrol, with optional detection and direction finding.
View modelsCell Phone Signal Boosters
Repeater and booster units that extend indoor cellular coverage in tunnels, basements, warehouses and remote sites, with band options matched to local operators.
View modelsCommunication Antennas
Fiberglass omnidirectional, panel directional, PCB and base station antennas for jammers, boosters and counter-UAS deployments, from 100 MHz to 6 GHz.
View modelsSignal Detectors
Detection units for locating unauthorized transmitters and monitoring spectrum activity across meeting rooms, vehicles and controlled sites.
View modelsAccessories & Cables
RF connectors, low-loss coaxial cables, power supplies, cooling fans and passive components that keep jammer and counter-UAS systems reliable in the field.
View modelsWhy buyers work with us
Shenzhen R&D, Dongguan production
RF design, firmware and final assembly run in house, so band plans, output power and mechanical fit can be adjusted for a project instead of being limited to a fixed catalogue.
Test data with every shipment
Amplifier modules and jammers are measured for output power, frequency range and VSWR before packing. Test records accompany bulk orders for incoming inspection.
Module and system level supply
Buy a complete jammer, a bare amplifier module, or the antennas, cables and power supplies around it. Matching components are quoted together so interfaces line up.
Export documentation support
Commercial invoice, packing list and product descriptions in English are prepared for customs and tender submission, with OEM labelling available on request.
