16-Antenna 5G Cell Phone Signal Jammer N16D – 1900~1990MHz Range, 25m Max Jamming Radius, CE Cert, MOQ 1pc OEM Supported

We're shiping these at 8kg per unit in a standard box, and the MOQ is just one piece — OEM support is avaliable if you need custom branding.

It cranks out 1W per band for a total of 16W, covering the 1900~1990MHz PCS range alongside CDMA800, which is pretty much what you need for exam halls or meeting rooms. 25 meters is max jamming radius, give or take, and CE cert is in the file. It runs a 72-hour full-load test at 35°C before leaving us — we log all the frequency accuracy checks across every band, so traceability is there batch to batch. Most buyers go with the N16D for school settings, but it also works in confidential zones. We usually have stock, but confirm lead time for large orders.

One thing it's not suited for is outdoor wide-area coverage — the radius is fixed, and obstacles (like reinforced walls) will shrink it. Actually, we've seen it hold steady in a standard classroom, but don't expect miracles through concrete.

The 16 antennas are what make it tick; each one handles a specific band, and you'll want to check the TDS for exact frequency splits. It blocks unapproved mobile and GPS signals without messing with adjacent devices outside the 25m zone — that's the design intent anyway. A concrete detail: the power supply has a built-in fan that kicks in after about 20 minutes of continuous use, so keep it ventilated.

So the 1900~1990MHz band is the main draw here, but CDMA800 is also covered, and the unit supports OEM branding if you need it. 8kg is teh weight, box is the package.
