our company can handle custom labeling and vial sizes pretty easily if you're ordering a production run, but the stock unit comes as a complete kit with three antennas and the power adapter. You'll see the power and current readout right on front display—that's handy when you're checking if the battery's actually holding a charge or the fans are pulling enough current.

It's not designed for continuous 24/7 operation, so don't plan on leaving it running all day—the 5-hour battery life is a hard limit before you need to recharge. Teh 29.4V lithium pack is a specific voltge, so if you lose the AC adapter (100-240V input), you'll want to order a replacement form us rather than grabbing something generic.

Basically each channel pushes 10W into its own antenna, and we've measured consistent jamming out to about 180 meters in open field conditions—the 200m spec is under ideal line-of-sight with no interference. The aluminum heat sink with dual silent fans kicks in automatically when it gets warm, which it will after about 20 minutes of continuous use.

We typically have these in stock and ship within 3 business days, but confirm lead time if you need more than 5 units since we occasionally run short on the 868MHz antenna batch. The 3kg package weight (2.12kg for the unit with antennas) means it's not a pocket jammer—it's a briefcase-sized tool you'd use for temporary blocking in parking lots or warehose environments.

ICNIRP compliance means it's safe from a radiation standpoint as long as you don't stand directly in front of the antennas at close range—the manual says 50cm minimum distance, which we'd recommend sticking to. For 315MHz and 433MHz car remote blocking (usually 2-4 weeks for custom frequency tuning if you need something specific), this covers the most common consumer and industrial bands without extra configuration.

Frequently Asked Questions

What is the minimum order quantity for the JYT-RF300?

We typically require a MOQ of 10 units for first-time orders, but we can discuss smaller trial orders if you reach out directly.

What is the lead time for the JYT-RF300?

Lead time is usually 7-10 business days for stock orders, and up to 15-20 days if we need to assemble based on demand.

Do you provide certifications or test reports for the JYT-RF300?

Yes, the unit is ICNIRP compliant for safety. We can share CE and RoHS test reports upon request.

Can I customize the frequency channels on this 30W jammer?

Yes, we can adjust the frequency bands (315/433/868 MHz) or add custom frequencies, but that may affect the jamming range and lead time slightly.

How should I store the JYT-RF300 when not in use?

Keep it in a cool, dry place away from direct sunlight. If storing for over a month, charge the lithium battery to about 50% to preserve its lifespan.
