Real talk—the VJ8 isn't a plug-and-play gadget for casual users, it's a 10kg beast that needs proper DC-12V/24V power form a vehicle battery, not a wall socket. But for what it does—creating a solid RF dead zone around a car to block bomb triggers or GPS tracking—it basically works as advertised if you handle teh setup right. I've dealt with buyers who thought they could just slap it on a desk, and that's not how it runs.
160W output across 700MHz-6000MHz means it covers 2G, 3G, 4G, WiFi, and GPS in one shot, but the eight omni-directional antennas are what make it work—you'll get a field, not a pinpoint. Most of our clients use it for VIP convoy protection or EOD units, where catching unauthorized signals matters more than absolute range. The weight (about 22 pounds) makes sense once you see the metal enclosure; it's not flimsy, just built for vehicle mounting with that dimensoin of 460×330×70mm.
our company can customize the frequency settings—trimming specific bands if you need to leave emergency channels or local LTE untouched—just tell us what you're blocking and we'll adjust the module list (lead time usually 15-20 days for that). Standdard units cover 700-6000MHz full sweep, but for bomb jamming scenarios, most buyers go with the custom filter to avoid interference with police radios.
That unit runs from -20°C to +60°C, which holds up in hot patrol vehicles or cold mountain ops, but humidity does creep in (5%-95% range) so keep the vents covered if you're driving through heavy rain. We actually had one guy mount it on a military Humvee and it worked fine after a year—none of that corrosion nonsense if you seal connectors right.
Pricing scales with volume: sample units run about $X, mid-volume orders get you $Y, and bulk lots drop to $Z per unit—roughly 30% less than comparable systems due to direct factory margins. Minimum order is usually 1 sample, but for custom frequency work we ask for 5 units or so to cover reprogramming overhead. Lead times average 4 weeks if stock runs out, but we typically have 20-30 units ready.
It's not ideal for fixed-site installations or tight indoor spaces—those antennas need clearance and basically dislike concrete walls—but for convoy ops or mobile response, it's solid enough that repeat buyers don't bother shopping around. Anyway, specs-wise COA covers power output per band, and you'll get that with the shipment.
Typically 7-10 business days after order confirmation, since we need to tune the 8 antennas to your specific frequency bands. Stock units with default settings ship within 3-5 days.
It's total system power — the 160W is distributed across all 8 omni-directional antennas, so each antenna outputs around 20W depending on the frequency mix.
Yes, we can supply CE, RoHS, and FCC test reports on request. For specific military-grade compliance, just let us know what docs you need and we'll arrange them.
MOQ is 10 units for a production order, but we do offer single-unit samples for evaluation — just cover the unit price and shipping.
Store it in a cool, dry place between 0°C and 40°C, ideally at 50% battery charge to avoid degradation. The battery can last up to 2 years in storage if recharged every 6 months.
