So you're looking at the PTC-D4, and the short answer is yes, it covers 315, 433, and 868 MHz with individual power knobs for each band—total output is 150W, but each band runs 25-50W depending on how you dial it in, and the jamming range is usually 100-800 meters, though that's heavily environment dependent, so don't expect 800 meters indoors through concrete walls.
It's basically a continuous operation unit, not pulsed, which matters if you need sustained blocking for testing or security appliction, and the cooling system handles that fine with an alumnum radiator plus two fans—we've run it for 8-hour shifts in a warehose and it stayed stable, no thermal shutdown issues.
What makes it relaible is the VSWR over-protection on each module, which prevents damage if an antenna gets knocked loose or a cable goes bad, and the AC 110-240V / DC 27V power input gives you flexibility for fixed installs or vehicle use—most buyers go with AC adapter included, but confirm if you need a DC-only variant.
Also, the antennas are 500mm omni-directional, four of them, and the whole unit weighs about 14kg without antennas, so it's not desktop-friendly for a small lab—you'll want a sturdy cart or rack mount, and the dimensions are 390×340×130mm, which is bigger than most expect.
One thing it's not suited for is GPS or Wi-Fi blocking—it's strictly 315/433/868 MHz for remote control signals, so if you need those other bands, this isn't the unit, but for drone jamming or garage door testing, it's better than most consumer-grade blockers we've seen.
Lead time is typically 10-15 working days, and we usually have stock, but confirm before ordering—MOQ is 1 unit, and we'll provide the COA and SDS with shipment, just note the shipping weight is around 18kg with packging, so factor that into freight costs.
We can do a single unit for sample testing, but for bulk orders the MOQ is 10 units per shipment.
Yes, we can provide CE and RoHS certifications with the shipment. FCC certification is not included by default but can be arranged at an extra cost depending on your destination.
Standard lead time is 15-20 working days after order confirmation and payment. For urgent orders, we can expedite to 10 working days with a small rush fee.
Absolutely—each of the three frequency bands has its own individual adjustment knob, so you can dial in 25W to 50W per band independently.
The unit comes with an aluminum radiator and two built-in cooling fans, so it's self-contained. Just keep it in a well-ventilated area to avoid dust buildup on the fans.
