ImmersionRC RF Power Meter v2

ImmersionRC RF Power Meter v2

In the world of FPV, your performance is only as good as your RF links. The ImmersionRC RF Power Meter v2.1 is an essential diagnostic tool designed to take the guesswork out of video (VTx) and control (R/C) links. High-end microwave test equipment usually costs thousands, but the v2.1 brings that professional accuracy to your flight bag. Whether you are a racer ensuring you stay at a legal 25mW or a long-range pilot verifying your gear’s health, this meter provides the data you need to fly with confidence rather than crossing your fingers.

Key Features

The v2.1 introduces Scully Mode, named after the legendary Joe Scully, which allows for “Touch-Free” race compliance. By using the included sniffer antenna, you can check a quad’s output power at the starting grid without ever touching the hardware. For those who want to “see” their data, the PowerScope Mode provides a visual representation of emitted packets, helping you identify duty cycle limitations or antenna issues in real-time. Additionally, the Integrated 30dB Attenuator means you can plug high-power transmitters directly into the device without needing external hardware.

Specifications

Built for the field, the device features a high-contrast OLED display and an intuitive joystick interface. It covers a massive frequency range from 35MHz up to 6GHz, calibrated in 50MHz steps for pinpoint accuracy. The internal 600mAh Li-ion battery delivers roughly 8 hours of continuous use, and the micro-USB charging port means you can top it off using a standard power bank or car charger in under an hour. With an accuracy of +/- 0.5dB, it is a “geek tool” that delivers laboratory-grade insights in a pocket-sized form factor.

Applications

For Race Organizers, this tool is non-negotiable for maintaining “Race Compliance,” ensuring no pilot accidentally “hammers” the field with high-power interference. Professional FPV Pilots use it to benchmark new video transmitters, verifying if they actually hit their advertised output or if they “thermal throttle” after a few minutes of flight. It is also an invaluable tool for troubleshooting R/C links (like Crossfire or ELRS), allowing you to verify that your radio’s internal antennas are oriented correctly and transmitting at the expected power levels.
