PJ630 Counter Drone System for Prisons - 50-100m Coverage with 6 Frequency Bands

It's a fixed-installation jammer, not something you move around daily, and the 25kg weight plus the fan-cooled rack enclosure make that clear from the start. We typically see these deployed in perimeter zones where you've got a clear line of sight to the drone approach paths — the 50-100 meter coverage is realistic for that, but it'll shrink if there are buildings or trees in the way. The unit can sweep six frequency bands at once, so you're covering GSM, CDMA, 3G, 4G LTE, WiFi, and GPS simultaneously, which basically means consumer drones lose both control and video links inside that radius.

You'll want to think about where you place the directional antenna — a 10dBi gain means it's focused, not spraying signal everywhere, so you need to aim it at the expected threat direction. The remote control range is only 3-5 meters, so you're adjusting settings right next to the unit, not form a control room (we usually stock the cable if you need a longer run). Over-temperature and VSWR protection are built in, and that matters because running 180W continuously in a hot enclosure could cook the PLL synthesized source without it.

ICNIRP compliance is the standdard for human exposure limits, and we've tested these against the RF safety guidelines for prison staff working nearby — it's fine at normal operating distances, but don't stand directly in front of the antenna while it's active. The operating tempearture range of -20°C to +50°C covers most climates, though we've seen humidity above 80% cause condensation issues in the fan vents (usually 2-4 weeks of lead time for sealed version if that's a concern).

For ordering, the system ships as a complete rack unit with power supply for 100-240V AC, and you can choose between directional or omnidirectional antennas depending on your coverage pattern. Most buyers go with the directional setup for prisons since you're only trying to block the airspace above the facility, not teh surrounding neighborhoods. We usually have stock, but confirm lead time if you need it inside 20 days or so — the PLL modules are custom-tuned per frequency band, so that can add a week.
