This is an ImmersionRC RF Power Meter. Sensitive and precise, the RF Power Meter takes the guesswork out of uplink and downlink power and antenna measurements. Calibrated on all bands used in RC modeling, from 35MHz through 5.8GHz.

Transmitter Testing
The ‘600mW’ transmitter installed on your FPV/UAV system, what does it really emit? The ‘2dBi Omni, coupled to it, does it really work as specified? These kinds of questions are often considered when theoretical range calculations don’t match reality, but answering these questions can be expensive.

Included Accessories

The supplied semi-rigid male-male SMA cable may be used for in-system testing, without removing equipment from your model. A 30dB attenuator is also included, to bring the power of most FPV transmitters down to within the range of the power meter.

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

Antenna Testing
Comparisons between antennas are simple with the power meter. Place a transmitter nearby, attach the antenna to be tested to the power meter, note the reading, and switch to the second antenna.
For directional antennas, connect the antenna to the power meter, and rotate it through each axis. Plot the measurements and the radiation pattern of the antenna is created.

  • Affordable RF power measurements, a fraction of the cost of similar equipment
  • Measure pulsed, and continuous RF power levels (e.g. UHF, and A/V Downlinks)
