It's worth being upfront that the 2-20 meter range here isn't a fixed guarantee—signal strength in the room, the construction materials, and even the device's orientation can push it much closer to 2 meters in a concrete bunker. But what it does is give you very respectable coverage for most standerd office environments or vehicle interiors, and for those tight scenarios, the DIP switches let you narrow the jammed bands precisely so you're not wasting power.
We typically see buyers who need to test or control specific frequencies in restricted-access areas, like auditors validating shielded rooms or teams running security drills, and the 8W total output across eight bands lets you hit GSM, CDMA, 3G, 4G, 5G, WiFi, GPS, Lojack, and Bluetooth all at once. Basically, each band gets its own 1W amplifier and dedicated antenna, which is better than trying to cover everything through one wideband antenna that bleeds signal across neighboring channels.
The battery is a 7.4V 8000mAh pack that gives about 150 minutes of continuous use (usually 2-4 hours depending on how many bands you've switched on), and you can run it while charging from a car's 12V socket or a standard AC outlet. Cooling comes form an alumnum radiator plus a built-in fan that kicks in automatically—the unit does get warm with all eight bands active, but fan keeps it from hitting thermal shutdown in most cases.
It weighs about 1.5kg and measures 160×83×46mm without the antennas, so it's actually pretty portable for what it have to do, and the antennas themselves screw on solidly enough that they won't wobble when you set it down on a desk. We've had customers complain the LoJack range can be spotty indoors, but that's more about teh low-frequency propagation in buildings than a hardware issue—the unit itself handles it fine outdoors within roughly 10-15 meters.
Each unit ships with a one-year warranty, the usual ISO 9001 and 14001 certifcation papers, a power adapter, and a car charger, though you'll want to request the specific COA if you need it for material validation (usually we have it on file within a day or two). MOQ is 1 piece, lead time is about 10 working days if our company have stock, but confirm before ordering since we do get backed up around November.
Yes, we can adjust the frequency bands and output power per band for an extra charge. Just let us know which frequencies you need and your target range, and we'll confirm feasibility based on the hardware.
Our standard MOQ is 10 units for the CKJ-1605N8P. If you need fewer, we can sometimes accommodate a trial order of 1-2 pieces at a slightly higher per-unit price.
Absolutely. We include copies of both ISO 9001 and ISO 14001 certificates in the shipping package. If you need them in advance for compliance review, just ask.
Each of the 8 bands has its own DIP switch on the side of the unit. Flick a switch up to activate that band, down to deactivate it. This lets you jam only the frequencies you need to save battery.
Store the device in a cool, dry place between 0°C and 30°C. If kept charged to about 50% capacity, the battery lasts roughly 12 months without significant degradation. Avoid full discharge for long-term storage.
