27 antennas feeding into a single 27W total output—that’s basically a distributed punch, not a single blast, so you get 10-25 meters of real-world coverage, not just a hallway-length dead zone; each channel handles something different: 2G, 3G, 4G, 5G, GPS, WiFi, even LOJACK—you can customize the bands from 100MHz up to 6000MHz, too (confirm lead time for exotic frequencies, though).

3.4kg with the antennas off, all crammed into 198×132×68mm, and it runs for at least 90 minutes on the built-in 15000mAh battery—but don't push it past 50°C ambient; three cooling fans and an aluminum heat sink keep it from cooking, and most buyers go with the AC adapter for continuous desk use (the thing will work all day plugged into 100-240V via the DC12V 10A supply).

Purity’s not a factor here, obviously, but you'll want included COA for accountability—each unit ships with a test report, and we usually have stock of teh standard 27-channel version (check lead time on custom bands).

It’s not for outdoor mobile ops—the 172mm antennas stick out, and the 10m minimum range means you need it inside a room or vehicle. We've seen buyers use it in conference rooms and theaters, but one dude tried it in a museum lobby and the 25m radius bled into a neighboring restaurant—so, match your space carefully.

Ordering: MOQ is typically 1 unit for this model, price varies with customiztion (roughly $800-$1200 for standerd 27-channel, plus shipping), and you'll get an SDS and TDS with each shipment (give or take 2-3 weeks for custom builds).

Frequently Asked Questions

Can the JYT-2780 block both 2.4GHz and 5GHz WiFi signals?

Yes, it covers 100-6000MHz, so both 2.4GHz and 5GHz WiFi bands are blocked. Just confirm which specific frequencies you need, and we can customize the modules accordingly at no extra charge.

What's the minimum order quantity for this 27-channel jammer?

MOQ is typically 1 unit for sample orders, but we offer volume discounts starting at 10 pieces. Lead time is around 7-15 business days depending on stock.

Do you provide certification or compliance docs for the JYT-2780?

We can supply CE, FCC, and RoHS test reports upon request. Just note that local regulations vary, so you should check if this device is legal to use in your area before purchasing.

How do you package the jammer for shipping, and what's its storage requirement?

It comes in a foam-lined carton with all 27 antennas, power adapter, and manual. Store it in a dry place between -10°C and +50°C — the built-in battery holds charge well for months.

Can the output power be adjusted to reduce the jamming range?

The effective range is fixed at 10-25 meters based on environment, but you can lower the range by switching to lower-power antennas or attenuators. We don't recommend modifying the main unit.
