We've been sourcing signal blockers for controlled environments for a while now, and this partciular unit came up when a client needed something more flexible than the fixed-frequency models we usually carry.
The GW-JN24 covers 24 channels from 135MHz up to 5900MHz, which basically means it hits 2G all the way through 5G plus WiFi and GPS—the 24W total output gives you a blocking radius of about 1 to 25 meters depending on signal strength at the site, and we've found that's usually enough for most meeting rooms or small testing areas.
What it does is run for roughly an hour on the internal battery, or you can AC 110-240V or DC 12V for longer sessions, and the aluminun radiator with three cooling fans keeps it from overheating even when we've run it for extended periods.
One thing that's pretty specific to this model is the 24 external omnidirectional antennas—they're all individually tuned, so you don't get the signal bleed you might see with cheaper units that try to cover everything with fewer antennas.
When you order one, you get the main unit (which is about 330 by 250 by 80mm and weighs 3.0kg gross), teh antennas, a power adapter, and a one-year warranty—ISO9001 certified, though we usually have stock but confirm lead time if you need custom frequency tuning for a specific band.
It's not really suited for outdoor use in the rain, but for indoor controlled environments it's been a solid performer, and most buyers go with the standerd frequency set rather than customizing unless they have a very specific requirement.
Our MOQ for the GW-JN24 is 10 units for standard orders, but we can discuss smaller quantities on a case-by-case basis if you're testing the market.
Lead time is usually 15-20 working days after order confirmation and deposit, depending on the complexity of your customization and current production load.
Yes, the unit is ISO9001 certified, and we can provide a copy of the certificate along with test reports upon request.
Absolutely. The 24 channels are configurable within that frequency range—just specify which bands you need, and we'll adjust the board accordingly before shipment.
We ship it in a sturdy carton with foam inserts. For storage, keep it in a dry, cool place away from direct sunlight, and the battery should be charged every 3-4 months to maintain performance.
