You’re tired of spotty signal blackout zones where one device still rings or pings through—this unit handles that with eight antennas on SMA connectors covering 850/900/1800/1900/2100/2300/2400/2600/3300/4800MHz, so 2G through 5G plus WiFi and Bluetooth get hit.

It takes about 20 seconds to reach full shielding from cold start, and the radius runs 1 to 20 meters depending on environment and signal strength—concrete walls drop it toward lower end, we’ve seen that in field tests.

Runs off AC 100-240V at 50-60Hz or a car’s DC 12V, and the built-in battery gives you 2-3 hours of cordless operation (usually enough for a conference session or a road trip). Operating temp is -30 to +55°C, so it handles hot trunks and cold service vehicles fine, but don’t expect it to work well near gas station pumps or hospital MRI suites—different shielding issues.
We do OEM branding at 50 units minimum—your logo printed, no mold fees, roughly 20-25 working days for the first batch after art approval. Warranty is two years included, and we’ll send a COA with HPLC purity data for teh internal components if you ask.

Payment terms are typically 30% deposit, 70% before shipment for first orders; T/T or L/C at sight works. Shippng weight is about 1.0kg per unit, dimnesions 215x215x75mm, we usually ship via DHL or FedEx for small lots—10-14 days door-to-door to most major cities.

Also, the cooling fan kicks in automatically under heavy load—you’ll hear it after about 15 minutes of continuous use, nothing unusual, but good to know if you’re setting it in a quiet room.
The shielding distance radius ranges from 1 to 20 meters, depending on signal strength and environment. In open areas with average signal, you'll typically get around 15-20 meters, but in strong signal zones it may drop to 1-5 meters.
Yes, we offer OEM service with a minimum order quantity of 50 pieces. You can print your brand logo on the device.
The built-in battery provides 2 to 3 hours of continuous operation. It's designed for portable use, like in a car or conference room without a power outlet.
We provide a warranty card, test reports, and a CE certificate upon request. The device is tested for stability within the specified temperature range of -30°C to +55°C.
Yes, it includes 8 antennas with SMA connectors, and they are fully detachable. This makes it easy to transport or replace if needed.
