Majority of YouLoops listed on eBay are not an Airspy product

Many thanks to SWLing Post contributor, Chris Smolinski, who shared the screen shot above of a “YouLoop” being sold by a vendor on eBay.

While the Airspy YouLoop is based on a public domain noise-cancelling passive loop design that dates back decades (a.k.a. the Moebius loop antenna) buyers should note that many of the “YouLoop” antennas on eBay are not manufactured by Airspy. The product titles are misleading in this regard:

The RTL-SDR Blog does sell the original Airspy YouLoops on eBay for $34.95 shipped (and, as you can see above, they seem to pop up first in the search results).

Many of the other loops being marketed as “YouLoops” on eBay cost around $23.00-25.00 shipped. About $10 less, but there’s no guarantee the toroid windings, for example, will have the same specs as the original YouLoop.

It’s easy to spot the YouLoop copies because the cross over and toroid enclosures are much larger than those of the authentic AirSpy YouLoop:

Compared with the Airspy YouLoop:

Airspy doesn’t own a patent for the YouLoop (indeed, they even suggest homebrewing one) so this isn’t a clone. Rather, buyers should simply be aware that, as far as I know, the only authentic new YouLoops are being sold on eBay by the RTL-SDR blog.

    The one I made following some of the posts here seems to work OK. It would be interesting to see some sort of performance comparison between the Airspy one and the clone. I’d consider buying an Airspy one is there were a reputable dealer in the US I could get one from.

      Yes they arèn`t originals, we know, but on Aliexpress they cost half as much as the original and they comes with a 6 metre cable.
      As gratbob said, it would be very interesting a side to side comparison of their perfomance.
      Greetings.

    the problem with those “chinese” models is that the re’s no info about the kind of transformer and core used, and this ciuld result in sub optimal if not poor performance

    I made one from the article that was linked here 😉 It was so simple…
    Surprisingly , it works really well with my XHDATA D-808, which I did not expect! . Signal strength is less than a vertical antenna in the back yard, but the noise level is waaay less.

        The external antenna input of the D-808 isn’t particularly high impedance – I haven’t measured it, but it certainly behaves during alignment and spec-testing like a middling-low impedance. Somewhere in the 50~200 ohms nominal range, and not too objectionably reactive anywhere across the radio’s SW range, is my general impression.

    Got mine from airspy.us. A lot of deception on ebay. Another example is ordering new old stock of Tecsun pl-660, if you get it from anon.co storefront, they promise to send the latest 2019 production model. Other sellers still in stock do not promise that.
