RF Power Meter V1 (ImmersionRC)

RF Power Meter V1 (ImmersionRC)
NOTICE: This item has been discontinued and is no longer available. To see details to the replacement RF Power Meter V2 (#RFPWR-002) please click here.

RF Power Meter: This affordable hand held RF Power Meter takes the guesswork out of checking a transmitter's power performance. It even allows antenna comparison testing. Calibrated on all popular RF bands found in FPV and R/C modeling from 35MHz through 5.8GHz.

You don't have to put your FPV model in jeopardy due to poor transmitter power or bad antennas. This RF Power meter will help you resolve RF performance related issues.

The meter and supplied attenuator have SMA connectors. If the transmitter that is being tested has an RP-SMA then our SMA-016 adapter is required (not included).


  • Measure pulsed and continuous RF power levels.
  • Measures frequencies in the 35, 72, 433, 868, 900, 1200, 2400 & 5800 MHz RF bands.
  • SMA Connector.
  • Includes 30dB external attenuator (Mini Circuits #VAT-30W+).
  • Includes 3-inch (75mm) long coax patch cable.
  • Readout in mW or dBm.
  • 50dB of dynamic range (-50dBm to 0dBm without the external attenuator)
  • Calibrated for accurate measurements.
  • Operates on 6V to 16V DC (50mA).
  • Common 2.1mm x 5.5mm DC barrel plug battery input.
  • May be powered from a USB port (Mini-B USB cable not included).
  • Please see the user manual for additional specifications.

Transmitter Testing
Use the supplied -30dB SMA attenuator and connect the meter to the transmitter (max 1W). The RF power output level is displayed directly on the integrated LCD display. Values displayed can be in milliwatts or dBm.

System Testing
Install in place of your A/V receiver with the transmitter at close range to measure the power level that your receiver will see. This includes the transmitter's power level, connector losses, antenna gain, and free space losses. Testing an aerial FPV system on the ground is much safer than testing while airborne.

Antenna Testing
Connect to a directional antenna and measure the actual radiation pattern. Or use the meter for field strength measurements and compare antenna gain on each of your antennas.

Production / After Sales Service
Quickly verify transmitters before sending them to your customer. Verify short range transmitter complaints on customer returns. Plus it's great for R/C clubs that want to offer their members easy access to tools that help ensure FPV succes.

Warning! Always use an RF attenuator when connecting the power meter to a transmitter. The provided -30dB attenuator will safely protect it from transmitters that are up to 1 watt (1000mW). Higher power transmitters will need an additional attenuator. Failure to do this will damage the meter and void the warranty.
