I have mine for over six months and it works great indoors, by the window (as in the video), with AirSpy HF+ Discovery SDR which has an in-built preamp. The SNR is fantastic in both HF and VHF spectrums.
I have built several of these, all with good results. The actual signal level obtained tends to be rather low, so a sensitive SDR like the Airspy HF+ or Discovery is best although RTL-SDR + upconverter also works well. On LW, MW and lower HF they are directional, like most loops. I have my original 60cm one in the attic, lined up for North American MW reception. One of Radio Devon's low-power MW Tx's on 801 kHz is on the same bearing, so I used a portable radio to set this up. I used RG59-Mini coax as I had a large reel of it. I have been able to hear several US East Coast and Canadian MW stations with my Airspy HF+.
Does the YouLoop work well with an SDRPLay RSP1A or is an AirSpy HF+ Discovery a requirement?
I have this YouLoop antenna and it works well.. I have it in front of my office window and I am hearing HF stations over 1000 miles away. I also tied some string from the top connectors to the bottom connectors to help keep the loop shape.
I've got two of them and they're great! A friend of mine made a similar antenna that also works great. With it I was able to listen to a station located in Cape Town, SAF distant almost 6,400km from my qth here in Brasil.
I use a plastic coat hanger with the hooks to hang mine.. works well.
I just ordered one and was thinking about how to hang it and this sounds perfect and easy! Thank you.
I run one with a Airspy Discovery+ and it is a nice setup. Great on MW and FM Broadcast, and makes for a good quick setup on HF. My first session had me listening to Montreal FM Bcast at almost 400mi away. The key is how well it matches up to the SDR. Too much signal or gain would be worse, especially for selectivity. The YouLoop is a great match with my Airspy, as well as a good antenna for any RTLSDR. It’s loads of fun, good performer, and a nice upgrade if you are using a HF portable.
Thank you so much. Have you ever used it inside your home? Your voice is made for broadcasting.
Anyone has measured SWR? My Youloop with 15m RG58 cable has SWR 10, on 9,5 Mhz. Is it normal or something is wrong in my system?
Great looking loop, using semi-rigid coax hadn’t occurred to me 🤦♂️ So thanks for the video and ideas 👍👏👏
Excellent antenna especially around the LW section. paired up with the HF+ Discovery makes a great portable setup. I wouldn't bother buying a copy as the real thing is cheap enough.
Did it work well ?
What SDR do you have? Do you think it'll work with RTL SDR?
It does work with an RTL-SDR
it works fine with RTL SDR.

Would this work on a vintage 1936 Silvertone tube radio? 500khz-15mhz? She works but has no antenna.
Not sure what country you life but me R5000 and JRC-NRD is deaf Only Vatican stad some time and ham some time german far far away from me location nederlands. Most noice 9 and 9+20 on a Mini whipe ant whit 30 meter cable on me Balcony. pfff
is the AirSpy HF+ Discovery where all the performance is coming from?
Hmm very interested you can in theory TX up to 250mw so I could try my WSPRlite but looking at the spec for SWR I wonder just how good or bad the result would be
Strangely enough I currently have my pi running WSPR but through my EFHW. I may switch it over to the YouLoop, but SWR is rather high on HF so not sure how well it will perform. Will report back soon, or just check my call sign on WSPR net in a few days :)
@@TechMindsOfficial ah ok swr looks bad across most of HF according to your chart but anyway I've bought one off aliexpress for £14 see what happens!
I also have this antenna and it is also works not bat with RTL SDR V3.
Same here, works fine with the RTS SDR
Wondering how this would compare to a randow wire I have up in my attic which is about 25 ft long?
I'm so happy to see someone using a fishing rod as a antenna pole. I'm using a 2.4m pole from Boyes (£11.50) as part of a grab bag SWL kit I've built with a fishing seat box and backpack attachment. The rod sits in the side pocket with a cable tie giving extra support. At the moment I'm just using an Xdhata AN-80 antenna and clipping it to my Tecsun Pl-368 handheld. With this setup I'm picking up CW in Russia and the USA.
Hi, any idea when we will see your review of the Discone antenna part of the kit - that's the one I'm really interested in. Thanks. 73
Funnily enough, I’ve just started recording that video today :) so hopefully in the next couple of days I’ll get the video out. Thanks for watching 🙏
I recently bought one of these and it works well. It picks up all sorts of stuff with my HF+ Discovery. The noise reduction is welcome in my RF-hostile apartment.
I built the diy YouLoop on the SWLing blog. My performance was marginal, To try and salvage the antenna, I decided to purchase an HF receive loop antenna amplifier LAMB-1A (ebay). What an improvement in performance. I installed it in a small project box with 3 weatherproof 'F' connectors in place of the balun. Attached the diy Youloop to its balanced inputs and fed the amp with a 12 volt bias-T and connected into the SDRPlay via some RG-59.. Worked great and had about 10db of directional null. Of course mine does not get the VHF band. That was a great tip, I'll have to drag out that original YouLoop and try that. Thanks for the video, great as always... de wb7ond
Maybe I missed it, but which Airsply are you using in this video?
Thanks for the video!
I have been playing around with this antenna design for about a week or so and it is pretty impressive indeed when paired up with the AirSpy HF+ Discovery. Signals are low with my older radios and SDRs, but my shady Malachite SDR works pretty well with a YouLoop.
I've built a couple of modular balun and crossover assemblies, as well as a one-piece soldered-together YouLoop. It's not that difficult.
Surprisingly effective baluns can be contructed from ferrites recovered from old VGA cables and folks have used various types of coaxial cable for the loop segments and feed lines. Information is out there.

Can you use 75 ohm cable to get the feed line into the shack without it having a negative effect on reception?
I wonder if there is a possibility to use two Youloops for better performance
(series, parallel or whatever).
Very nice demo, TNX 4 the upload !

Great review, thanks for sharing.. Looking forward to see your review of the discone antenna which comes in the kit. Planning to buy the indoor antenna kit but will wait for your review of the discone antenna.
Very good review. I will probably pick one of these up. Thanks!
Thanks for sharing key knowledge.
can you tx?
No sorry it's Receive only.
I've had this antenna for a while now, and it works really well. It works so well that I rarely switch from it to the MLA-30+ or 53ft long wire. It just works. Really cuts down on rfi. (rspdx sdr as well as fgr-7)
I only wish it worked with my BELKA-DX. There are videos of people using one on BELKA s, but mine acts like I put a pair of earmuffs on it when I try to use this antenna.
Us aliens have one too
I take it that the 2m was through a repeater? I've seen a few loops, the Americans love them
Nope, not through a repeater, it was SSB direct, around 100km away the beacon is.
@@TechMindsOfficial hey that was good going.
For god's sake reduce gain on MW all that spikes are saturation
It’s not saturation at all, you think I don’t know how to use gain? Those spikes are local QRM and are present even with gain dropped.
@@TechMindsOfficial The medium wave and long wave tests was rather pointless. Talk Sport or whatever it's called now on 1089kHz and Radio 4 on 198kHz are about as far from difficult DX as you could possibly choose. Also why on earth are you still using an Airspy One with an upconverter? Why not get an Airspy HF+ Discovery?
I have a HF+, I have most SDRs, but that’s the gear I chose for this video.
