High Power 200M Range Prison Signal Jammer with 6 Frequency Bands for Military and Government Use

Comes down to that 300W total output, which is honestly a lot of RF to push in one chassis, and we've found it handles continuous duty cycles well even in environments with high ambient interference.

The sweep jamming method means it steps through each band rather than blasting all six at full power simultaneously, but that actually lets you cover more ground with less heat buildup because what it does is rapidly cycle across GSM/CDMA/DCS/3G/4G/WiFi or GPS depending on how you configure the modules — we usually have stock for the GSM/CDMA/DCS/3G/4G/WiFi combos but check lead time on VHF/UHF modules since those are less common in prison setups. The 12-15dBi antenna gain is directional or omnidirectional depending on your mounting choice, and most buyers go with omnidirectional for 360-degree coverage inside a yard or perimeter. Remote control range is only 3-5 meters, which seems tight until you realize you're usually running this form a protected control room anyway.

Just so you know, the PJ650 weighs 100kg gross packed, so you'll want a dolly or two people to move it around once it's crated.

It's not great for outdoor mobile use really because the fan-cooled system draws in dust if you run it in open air without a filter enclosure, and the operating tempearture range of -20°C to +50°C covers most climates but the storage range at -40°C to +60°C is tighter than some hardened military gear we've seen. In high humidity above 80% teh fan bearings tend to wear faster, so we recommend keeping it in a climate-controlled booth or at least under some kind of shelter.

slow start-up circuitry is something many buyers don't think to ask about but it prevents that big inrush current from tripping breakers when you power it on (usually 2-4 weeks lead time if you need a specific frequency configuration like the UHF modules). Anyway, the ICNIRP compliance is standard for these, though we don't have the specific SAR test data on hand for every band combination — you'll get that with the COA if needed.
