Product Overview

The Vodasafe VS-RC40 is a professional-grade portable 4-band RF signal jammer designed to block remote control signals across 315 MHz, 433/434 MHz, 868 MHz and 915 MHz — the frequencies most commonly used by RC cars, drones, wireless remote triggers, garage door openers and home automation devices. Built around a 40W total output (10W per independent band) and four 3dBi high-gain omni antennas, the VS-RC40 delivers a shielding radius of up to 200 meters, giving you reliable control over the wireless signals in your environment.

Housed in a rugged anti-oxidation aluminum alloy chassis with dual silent cooling fans and a built-in 29.4V 5000mAh lithium battery, the VS-RC40 runs continuously for up to 5 hours on a single charge. An LCD display shows real-time power, voltage and current, while a slow-start circuit protects both the device and surrounding electronics. Lightweight at just 3.12 kg with a built-in carry handle, it is built for field deployment, personal privacy and professional security use.

Key Features

4 Independent Frequency Bands

The VS-RC40 covers the most widely used remote control frequencies in a single handheld unit, each driven by its own dedicated antenna and power channel:

·        315 MHz — garage door openers, car alarms, RC toys

·        433 / 434 MHz — wireless remote controls, doorbells, sensors

·        868 MHz — European ISM band, home automation, remote triggers

·        915 MHz — US ISM band, drones, industrial remote controls

40W High Power Output

Each of the four channels delivers 10W of clean, stable RF output, totaling 40W across all bands. The independent channel design ensures that one band does not interfere with another, providing consistent blocking performance simultaneously.

Up to 200-Meter Shielding Radius

Four 3dBi high-gain omni-directional antennas provide 360-degree coverage with a shielding radius of up to 200 meters, depending on the signal strength and environment. Suitable for securing meeting rooms, vehicles, field operation sites and restricted areas.

5-Hour Built-in Battery

The integrated 29.4V 5000mAh lithium battery powers the VS-RC40 for up to 5 consecutive hours. An included AC adapter (100-240V, DC 29.4V 2A) keeps the unit running when wall power is available.

Aluminum Alloy Body with Silent Cooling

The chassis is machined from anti-oxidation aluminum alloy — lightweight yet durable. Two high-speed silent fans, combined with integrated heat sinks and side ventilation slots, ensure stable operation during extended use without excessive noise.

LCD Display and Smart Circuitry

The built-in LCD screen displays real-time power, voltage and current, so you always know the device status. A slow-start circuit prevents sparks on power-on, while high-performance integrated circuits and SMT assembly ensure long-term reliability.

ICNIRP Compliant

The VS-RC40 meets international ICNIRP standards for human-safe electric field (SAR) levels, making it suitable for use in environments where human safety is a priority.
