Picture a security team setting up a perimeter around a sensitive government building, and they need to block unauthorized cellular signals in a specific band — that’s exactly when this unit gets pulled from a pelican case, not a desk drawer, because of that it’s built for real field work more than stationary use.

The SDR-10JM is basically a profesional-grade jammer that covers GSM900 from 925 to 960MHz, and we see most buyers customize the output power anywhere form 5W to 100W depending on their enviornment, which directly affects that jamming radius — it’s roughly 20 meters in a dense urban area but can stretch to 2000 meters in open terrain, signal-dependent of course.

It runs on DC power at 24 to 28 volts, drawing about 0.8 to 5.5 amps per module depending on how many bands you stack — power consumption per module sits between 8 and 170 watts, so you’ll want to plan your power supply accordingly, and we typically recommend a regulated 28V supply for consistent performence.
Size-wise, it’s 80 by 46 by 20 millimeters and weighs 0.5 kilograms, which makes it pretty easy to mount into a custom enclosure or rack setup, and the SMA connector for the antenna is standard — you can pair it with omnidirectional or directional antennas depending on whether you want blanket coverage or a targeted beam.

We usually have stock, but confirm lead time for customized output levels above 50W because those modules sometimes require a build of 20 units or so before we schedule production — MOQ on standard models is just 2 pieces, though, and every unit ships with FCC and CE cerification plus a 1-year warranty.

One thing new buyers sometimes overlook is that this jammer isn’t designed for continuous full-power operation in scorching environments above 50°C or in high humidity above 95%, so if your deployment site is a boiler room or tropical outdoor setup without ventilation, you’ll need to factor in active cooling — the metal casing does shed heat well, but it has its limits.
We typically require a minimum order of 10 units for the SDR-10JM, but we can discuss smaller quantities for first-time buyers or specific projects.
Lead time for custom power configurations, such as 75W, is usually 2-3 weeks depending on current production load.
Yes, we include copies of the FCC and CE certificates with each order so you have the documentation for compliance purposes.
Absolutely, the 80×46×20mm size is adjustable based on your requirements. Just let us know the exact dimensions you need.
We recommend storing it in a dry, temperature-controlled area, ideally below 40°C, and using moisture-absorbing packs if the humidity consistently exceeds 60%.
