We've been moving a fair amount of the JM171544 lately, and the thermal alumnum shell is the first thing people notice — it's built to run 24/7 without cooking itself, and at 5kg it's not flimsy, but you can still mount it on a wall if you're clever about the bracket situation.
Actually, adjustable per-band output up to 16W total is what most buyers care about, because you're not stuck blasting everything at full power; you can dial down the WiFi band if you're only trying to knock out GSM and UHF, and that's pretty handy in a conference room or exam hall where you don't want to fry every device in teh building.
So the jamming range is listed at up to 25 meters, but that's under ideal conditions — in a concrete bunker or a metal-lined room you're looking at maybe 10-15 meters, give or take, and we usually tell people to test it on site rather than trust the spec sheet blindly.
Government and military buyers are the bulk of our orders here, but we also see a steady stream of security firms and corporate facilities — one client used it to quiet down a boardroom during sensitive negotiations, which is a use case we didn't think of but it works.
Lead time is typically 20 business days or so, and we require a minimum order of 5 units for the first run, but we can ship smaller quantities if you've got an urgent need and we have stock on the shelf — just confirm before you place the PO.
What it does is block GSM, CDMA, DCS, PCS, WiFi, UHF, VHF, 3G, and 4G, but it's not suited for 5G or satellite signals, so if you need those blocked you're looking at a different unit entirely.
Yes, the 16W total output power is adjustable per band, so you can dial up or down each frequency independently to match your specific jamming needs.
It's UL and CSA certified, and yes, we can provide copies of the certification documents upon request for your compliance review.
It's environment-dependent—up to 25 meters in open areas with clear line of sight, but walls and interference can reduce that range.
MOQ is 10 units, and lead time is typically 15–20 working days after order confirmation, depending on customization needs.
The thermal aluminum shell acts as a natural heatsink, so it handles continuous operation without extra cooling, even in temps up to 55°C.
