If you're dealing with unwanted signals bleeding into a secure space, you probably already know the frustration of a device that can't keep up, and with 16 antennas covering CDMA800 through 5G plus WiFi and GPS, this one should handle pretty much any band you're throwing at it.
The UHI-J16 pushes 16W of output power—and we've found that's usually enough for a 5-25 meter radius depending on your enviroment—with a built-in 12500mAh battery that gives you about 2 hours of continuous use or so when you're off mains.
It's got an LCD showing votage, current, and power, which actually helps when you're tweaking the DIP switches or using the remote to dial in coverage, and the cooling fan plus heatsink means you won't hit thermal shutdown mid-operation even on a hot day.
Most buyers go with the silver chassis for discreet setups, but the 3.2 kg weight is worth noting if you're moving it between rooms—it's not a backpack unit, more of a stationary or vehicle-mount solution (check your mounting bracket needs).
We typically keep stock on these, but the MOQ is usually 5 units for a custom frequency trim—if you need something like a narrower band split or different antenna gain, just let us know and we'll quote it.
Shippng runs 20-25 working days via air freight, and you'll get teh full set: remote, power adapter, 16 antennas, and a COA with HPLC data (we usually have that batch-matched in about a week after order).
Yes, you can adjust the effective range between 5 and 25 meters using the DIP switches on the device. This lets you fine-tune the coverage for smaller spaces or larger areas depending on your needs.
You’ll get about 2 hours of continuous operation at max power with the internal battery. If you lower the output via DIP switches or use it intermittently, that runtime can stretch a bit longer.
We can supply CE and RoHS documentation on request. FCC certification isn’t standard for this model since it’s designed for export markets, but we’ll share whatever compliance docs we have for your region.
The built-in fan works with the aluminum heatsink to keep the internal temperature stable during continuous use. For extended sessions over 2 hours, we recommend plugging it into AC power so the battery isn’t taxed, and the fan will keep everything cool.
MOQ is 10 units for stock models. Lead time is usually 7–14 days after order confirmation, depending on current production load. If you need a smaller batch, we can sometimes accommodate a sample order first.
