Handheld 350-1090MHz UAV Frequency Jammer 200W with 4 Channels (300m)

Frequency coverage determines what can be addressed. Output power determines how far the signal can reach. The J-RR4 combines a 350–1090MHz operating range with 200W total RF output, supported by four independent RF channels.

Features of portable UAV frequency jammer:

A Broad Frequency Window from 350MHz to 1090MHz

Many quadcopter communication links operate across different frequency sections rather than staying within one fixed point. The long-range signal jammer for drones covers a wide spectrum from 350-1090MHz, bringing multiple frequency ranges into a single device.

This wide coverage eliminates the need to switch between different units when working across supported frequency bands.

200W of output power distributed across four independent channels for a coordinated system

The high-power anti-drone blocker uses four independent RF channels, each delivering 50W of output power.

Every RF channel is paired with its own antenna, creating a one-to-one RF architecture throughout the system.

Under open-field conditions, the interference range reaches up to 300 meters.

Suitable for outdoor use

Outdoor equipment faces more than just signal challenges. Dust, moisture, and temperature changes can affect long-term operation.

The handheld FPV system signal blocker housing reaches IP65 protection, providing protection against dust and water spray. Operating temperature range:

• -20°C to +70°C

Dual Power Supply

Two power inputs are available:

• 220V AC input
• 24V DC input

The dual-input configuration allows installation in locations using either AC mains or DC vehicle power.

High-Power Hardware in a Portable Format

A 200W system usually means a larger enclosure, but the J-DR4 drone jamming system keeps the structure compact:

• 360 × 250 × 170 mm (without antenna)
• Weight:Approx. 11 kg
