The JYT-1800 is a professional-grade 18-antenna signal jammer designed for comprehensive signal blocking in secure environments. This multi-functional device effectively interferes with all common communication frequencies including mobile networks (2G, 3G, 4G, 5G), WiFi signals (2.4GHz, 5.2GHz, 5.8GHz), GPS tracking systems (L1, L4, L5 bands), and various RF frequencies (315MHz, 433MHz, 868MHz).
With a total output power of 44W distributed across 18 independent channels, this jammer provides reliable signal disruption within a 40-70 meter radius, depending on local signal strength. Each frequency band features dedicated output power ranging from 1W to 3W, ensuring effective interference across all targeted spectrums.
The device comes equipped with a convenient remote control system, allowing operators to toggle individual frequency bands or the entire system without physical access to the unit. This feature is particularly useful in dynamic security situations where quick adjustments may be required.
Built for continuous operation, the JYT-1800 incorporates a robust cooling system with five high-performance fans to maintain optimal temperature during extended use. The unit supports both AC power (110V/220V) and DC 12V car battery connections, making it suitable for both fixed installations and mobile applications.
Typical applications include examination halls in educational institutions, secure meeting rooms in corporate environments, sensitive areas in government facilities, and safety-critical locations like gas stations and hospitals (with proper testing to avoid interference with medical equipment).
The complete package includes the main unit, 18 omnidirectional antennas with 4-5dBi gain, AC power adapter, car battery adapter, and remote control. With dimensions of 450×238×60mm (excluding antennas) and weighing 7.5kg, the device offers powerful performance in a relatively compact form factor.
For specialized requirements, we offer frequency customization services to tailor the jammer's performance to specific operational needs. The unit comes with a one-year warranty from the delivery date.
While the delivery was prompt and the packaging secure, the overall experience was disappointing. The product itself feels quite flimsy and the remote control is unresponsive.

I cannot recommend this based on my experience with the product quality and post-purchase support.
