ImmersionRC V2.1 RF Power Meter
FPV is made possible by two RF links, a control link and a video link. Without an RF power meter, a pilot has no way to test these critical RF links. Test equipment for microwave (GHz) links is not cheap. ImmersionRC changed this several years ago and provided their “Power Meter v1” to the FPV community. The v2 is the result of listening to customer feedback. ImmersionRC has added an internal battery, internal attenuator and other features that every FPVer needs.
Accurate RF power measurements
Is the latest whiz-bang hype-train vTx really as good as the datasheet claims? Does it really put out 25mW on all race channels? Is it still putting out 25mW 30 minutes later?
The RF Power Meter v2.1 helps you answer these and many other questions.
In the early days of FPV racing, ImmersionRC pioneered low power racing, where everyone runs 25mW. This became a worldwide standard within months and continues to be the standard today. The Power Meter v2.1 gives you the measurement tool you need to test your transmitters before you get blown away by your next race.
Non-contact race compliance
Are you ready to test your video transmitter before the hammer comes out?
With the included stubby dipole, the RF Power Meter v2.1 is all you need to do a rough power test on any FPV rig, even without unscrewing the antenna. Calibrate the meter on a “known good” rig and walk the starting grid testing every quad ready to race. Quads accidentally set to high power (ready for the hammer) or those with hardware/cable/connector/antenna issues putting out a few micro-watts are identified before the first gate.
We call it “Scully Mode” for a reason. Joe Scully, the industry’s top FPV MC, has perfected this testing technique to ensure successful racing in all four corners of the globe.
PowerScope Mode
So you know that “packets” of data are flowing from your R/C Tx, or long range system, to your model… but what if you could “see” them? The PowerScope mode of the RF Power Meter v2.1 gives you a visual representation of the power your radio is putting out. How fast are the packets going out? Are your radio’s multitude of antennas working? Where are they? What orientation? You can even spot transmitters that are compliant with LBT (listen before you speak) or Duty Cycle limitations.
Yes, it's a geeky tool, but it impresses the opposite sex!
Average and peak measurements
Analog video transmitters emit a steady stream of RF goodness. R/C controllers emit a pulsed stream of goodness (going in the opposite direction). The RF Power Meter v2 can provide accurate power measurements for both types of RF signals.
Built-in lithium-ion battery
The v2.1 features a built-in lithium-ion battery that will power the meter for at least 8 solid hours. With automatic shut-off after periods of inactivity, a single charge will power your meter for days on the trail. Rechargeable using a standard micro-USB connector in under an hour.

Under the 24-month Legal Guarantee, Drone24Hours is responsible to the consumer for any defects in conformity that cannot be detected at the time of purchase.
The lack of conformity exists when the product is not suitable for the use for which it is normally intended, does not conform to the description or does not possess the qualities promised by the seller, does not offer the qualities and performances usual for a good of the same type, is not suitable for the particular use desired by the consumer if brought to the attention of the seller at the time of purchase and accepted by the seller (art. 129 of the Consumer Code).
Any lack of conformity which becomes apparent within 24 months of the date of purchase of the goods must be reported within 2 months of the date of discovery of the defect.
Unless proven otherwise, it is presumed that any lack of conformity that becomes apparent within 6 months of delivery of the goods already existed on that date. In the event of a lack of conformity, the consumer has the right to have the conformity of the goods restored, free of charge, by repair or replacement (art. 130 of the Consumer Code).
The consumer may ask, at his choice, the seller to repair the goods or replace them, free of charge in both cases, unless the requested remedy is objectively impossible or excessively expensive compared to the other. Repairs or replacements must be carried out within a reasonable time from the request of the Consumer; the average time for returning the product to the Consumer is 20 days.
If Drone24hours is unable to return the repaired product within the maximum period of 60 days, the consumer may request one of the alternative remedies (replacement, termination of the contract, price reduction).
Drone24Hours will send the product for any repairs to the Technical Assistance Center authorized by the Manufacturer.
What happens if the Service Center does not find the lack of conformity?
If the lack of conformity is not found, Drone24Hours will communicate the estimate to the Customer, who can decide whether or not to carry out the repair at his own expense. In this case, any transport costs and diagnosis of the defect requested by the Assistance Center will be borne by the Customer.
