Description

ImmersionRC RF Power Meter V2.1FPV is made possible thanks to 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.

FPV is made possible thanks to 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 added an internal battery, an 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 emit 25mW on all race channels? Does it still emit 25mW 30 minutes later?

The RF Power Meter v2.1 allows these questions, and many more to be answered.

Back in the early days of FPV racing ImmersionRC pioneered low-power racing, where everyone runs 25mW. This became a world-standard within a few short months and continues to be the standard today. The Power Meter v2.1 gives you the measurement tool that you need to test transmitters before you get surprised at the next race.

Touch-Free 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 that you need to perform a rough power test on any FPV platform, even without unscrewing its antenna. Calibrate the meter on a known good platform, and walk down the start grid testing each quad ready to race. Quads accidentally set on high power (hammer-ready), or those with hardware/cable/connector/antenna problems emitting a few micro-watts are identified before the first gate.

We call this Scully Mode for a good reason. Joe Scully, the best FPV MC in the business, perfected this test technique to ensure successful race meets on 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 presents you with a visual representation of the power being emitted from your radio. How fast are they packets emitted? are the multitude of antennas on your radio working? where are they? what orientation? You can even spot transmitters which comply with LBT (listen before talk), or Duty Cycle limitations.
Yeah, it is a geek tool, but it does impress the opposite sex!

Average and Peak Measurements

Analog Video Transmitters emit a steady stream of RF goodness. R/C Controllers emit a stream of pulsed goodness (which just happens to be heading in the opposite direction). The RF Power Meter v2 can deliver accurate power measurements for both types of RF signals.

Integrated Li-ion Battery

The v2.1 contains an integrated Lithium Ion battery, which will power the meter for at least 8 solid hours. With auto-shutdown after periods of inactivity, a single charge will power your meter for days at the race track. Recharged using a standard micro-USB connector in less than one hour.

Extremely temporary solution to pants
Size: 33W x 32L, Color: Stone Medium Wash
Very comfortable and good fit. But...they're extremely fragile. I bought three pairs one after the other as each failed. Typically only got a month or so of wear-time before a giant rip would appear along a major seam. Great if you need a quick/temporary pair of jeans. Terrible if you plan to use these jeans for more than a couple of wash cycles.

Amazon essentials jeans
Size: 36W x 30L, Color: Stone Medium Wash
Wasn’t sure what I was going to get for such a low price, very happy with it. When I told my wife I bought a low priced Amazon essentials pair of jeans she said I shouldn’t wear them when I go out, just around the house and yard. After they arrived and I tried them on she changed her mind, said I should get several pairs. They fit perfectly and look great. Always appreciate a good deal!

Great jacket
Size: Large, Color: Antique Indigo, Size: Large, Color: Antique Indigo
5’ 10”, 160 lb, 46” chest, 38” waist. I bought a size L jacket in antique indigo. I thought it might be too tight, but it fit perfectly, with enough room to wear a layer underneath. The sleeves were a good length, with maybe ½” extra for shrinkage in the wash. It was difficult at first to button the jacket. I cleaned up the button holes carefully with a small pair of scissors and now it’s much easier. I had tried the Levi’s Men’s Trucker Jacket, also in a L. It felt a bit snug in the chest and tight under the shoulder. Not much room for layering. I decided to keep the Wrangler jacket. The fit is looser. I like the the square chest pockets (which will actually hold something) and straight vertical seams over the Levi’s small, tapered pockets and diagonal seams.

Read the reviews to choose CORRECT SIZE
Size: X-Large, Color: Antique Indigo
A is offering discounts on some sizes, but caution is needed to avoid a mistake. My husband makes this review: * I am 6' 0" tall; 215 #; chest 44"; waist 39" * XL fits very, very well. This is a "waist jacket", and I am old enough to call it an "Ike" or "Eisenhower jacket" * The fit is flattering; but there is space available for a medium sweater. * I typically wear a size 16 1/2 neck and a 34" sleeve--I have some welcome space at the neck and the sleeve extends about 1-1 1/2" below my wrists--I like this a lot * I wanted the lighter color, BUT I saved about $15 with the darker. * Reading reviews here, I DID wash it the first time with 1/4 cup salt and 1/2 cup vinegar--I believe the suggestion was made for purposes of "fixing" the color. [Warm wash and cold rinse.] * Post-wash girth and length remained the same. * NO SMELL, PRE-WASH or POST-WASH. * "Fit and finish" was very good; no defects of any kind seen; fabric quality is sturdy. * I find it a handsome and useful weight/size. I live in the Central Cal. desert, so we do not see much cold, even in Winter. I expect many years of use for this garment. At current 30% off, this is a COMPELLING bargain. [Sorry, I do not take photos.]
