Custom configurations are something we handle regularly—vial sizes, custom labeling, even tweaking output power for specific band requirments—but teh base unit here is ATJ6-600-5, and most buyers just want it working out of the box. 2. You're looking at a 600W total RF output across 20-6000MHz, which covers 2G through 4G, GPS, WiFi, and Bluetooth; the power draw is 2100W, so make sure your facility has the DC-48V supply ready because this thing isn't plug-and-play on a standdard outlet. 3. We usually ship with six jumpers and a six-port antenna included, but confirm lead time on custom frequency splits because we've had some orders where the 5G slice took 20 days or so to tune. 4. It's heavy—50kg—and the IP65 rating means you can mount it outdoors without worrying about rain or dust, but one thing you might not think to ask: the operating range is -20°C to +55°C, so if your location sees sustained temps above that, you'll need active cooling or derate the power. 5. Most buyers go with the full band version for prison or government facilities, but for smaller areas like a boardroom or perimeter zone, 200W units are actually easier to handle and still block everything within 50 meters or so. 6. The MTBF is listed at 50,000 hours, but that's under ideal conditions—real-world heat and vibration can cut that down, so we recommend stocking a spare power module if uptime is critical.
