People commenting on the loop's efficiency compared to randoms and dipoles apparently have no idea over conditions in a city/apartment, not to mention HOA restrictions. A loop is a godsend design for people like us, and when properly tuned and amplified, they work wonders. You may not be catching any Brasilian AM stations, but they still offer some great DX opportunities.
Agreed! Yes, some obnoxious know-it-alls wish to remain ignorant of both some of our housing and HOA restrictions as well as the limited physical capabilities of some of us that keep us from hanging off ladders 20 feet up. Yes, mag loops can help us out.
That's what you get from a contest. 5/9.. repeat your call ? LOL they are nonsense but i won't start . It's just a 5/9 for the log but you'll never know the real report wich is a basic thing to tell .
Nice looking antenna, well built, reminds me of a few times I worked some DX off my Cantenna Dummy Load sitting on the shack floor!. always got a chuckle out of that!. I also worked a guy on 6m one time that loaded up his Volkswagen bumper! Cheers es 73!
I just purchased one of these today on his eBay page , the reason for purchasing was down to the stable looking design, I have home-brewed a few using old radio capacitors and various coax , aluminium loops but my efforts were always substandard, some day I will invest in a 3d printer . I wonder if you have done any follow up videos with good band conditions, could also be used in conjunction with Xphase QRM Eliminator as your aux input to get rid of bad over the horizon qrm radar/woodpecker/ noise as well as local noise in both horizontal and vertical positioning
Unfortunately I gave this antenna to my friend, on a permanent loan! I have too much gear here to keep around so I needed the space. I believe many people are using these.
Thanks for the video! On disadvantages you mentioned that the loop antenna had a narrow bandwidth but I suppose it is not a disadvantage because to tune this antenna in we must always use the capacitor.
I wonder if this type of antenna can help people get around planning regulations? Would such an antenna be measured by local authorities by its diameter or circumference? Another thought I had is that a very fast spinning magnetic loop antenna could be omnidirectional.
Being directional then having to tune the antenna would get old, but if space is a concern this would be a great option. It would also work good for people with deed restrictions/HOA. But man, that is one nice looking loop!
I have one of these and it works well, mine is in the loft and right next to a velux window. only downsides i can see is its not waterproof, so not suitable for full time outside and the switch has to be manually switched to extend the range.
I thought exactly the same. Even on this video I had (as non-native English speaking person) problems to understand the "q" the first times. Because I was expecting a Nato-Alphabet term.
I have the same loop bought from 2E0ERO earlier in the year. Initial setup indoors just behind the patio doors gave better results than I was expecting despite it being stood on the floor. As soon as time allows and the weather improves I'll be mounting it on a decent portable mount and getting it a little higher of the ground. General consensus seems to be 1m to 2m so I plan on using a tripod that's easily portable. Did you try it at different heights?
test it by placing the two loops parallel to the ground, that is, horizontal: in theory this will be omnidirectional but it will only pick up the signals that arrive from the horizon (which are the interesting ones) and not those that arrive "below" the horizon, thus it will capture less radio noise generated in the population's homes.
Hi Nick, do you have the website where I can order? With your experience is the antenna water tight? With the Video I can see the tuning capacitor is exposed. Any suggestions? Jojo
I have the AlexLoop (for SOTA) and the Ciro Mazzino (spelling??) Baby loop. While I like them one huge drawback is the obvious need to retune when changing frequencies which makes contest participation painful. Another big limitation is the inefficiency of a loop at its lowest operating frequency (7MHz in your example) and I suspect that this one is no different. Final comment is the peak angle of radiation in the vertical plane is quite high (~40-60 degrees) making DX more challenging. FWIW I think using at ATU a big “no no” with a loop given the sharp Q of a loop.
I am really excited to receive this antenna, just ordered yesterday! I live in Alaska and am very interested in the performance of this type of antenna here. 73's de AL9G
I found it good for CW and digimodes, bad for SSB (low efficiency). Mounting horizontally gives better omni-directionality. Keep away from metal things as it detunes it.
How do I purchase one of these??? I see no link in your description above... As well as being an amazing ham radio resource - you are an effective salesman as well.... tell us where we can purchase this .... please....
2E0ERO makes a CB one but this one tunes at 27MHz I had a go with 4 watts FM last weekend worked a guy 15 miles away we chatted for 20 minuts no issue so it works but not much CB in my area to test it fully
Wouldn't this Antenna work far better 50 or so feet above ground? You could just build a Antenna Rotator from a Car or Truck Windshield Wiper Motor and a Few Gears and some Electronics components Mate. Also, could you use a hand full of Electronic Solid State Crystals at what ever Hertz you desired to help fine tune your Stations? Just asking. Thanks for the upload.

Nice intro, but using the international phonetic alphabet may have helped with your ident with the Russian station, especially with Amateurs where English is their second or third language.
It’s always a tricky one that because it’s also quite possible that they had qrm, as opposed to receiving a weak signal. But yep, agree, too many 5/9 and I’m guilty of that too especially if I forgot to look at the S meter :)
What diameter pole did you use there? I can't find anything that will fit the mounting or did you give Adrian your own custom measurements before printing?
Unfortunately I don’t have the antenna anymore as I have it to one of my friends. But I measured the mount that comes with it and ordered a short tube with the correct diameter from Amazon or EBay, can’t quite remember.
it would help if he started to say quebec instead of queen or qjubek :-) i noticed that the letter "Q" in his spelling alphabet is his archilles heel. can still be readibility 5 and signal 9 - but if the pronounciation is not understood as people are not familiar with his regional dialect - then it is similar to a 5NN on telegraphy, with people doing QSD (defect sending... irregular timining on the morsekey) Bah, i think youre right though. Folks have forgotten there are more numbers than the 5 and the 9 :-) "HUsband, when you go to the store... bring me 2 cucumbers !" "sure babe, 5 cucumbers it is" I have the same problem with the x-ray. Nodbody on the bands wants to understand the x-ray. I think when the (german) gov issued me that particular callsign back in the 80ies , it was an early form of "yes, you passed the exam... but we found a way to screw you anyways" - trolling.
I think if you used proper phonetics giving your callsign and not random words (queen) then the other station knows what words to expect and therefore understand. As soon as you throw a random word in it can be very confusing. Just my thoughts.
@Steve Jenson Not sure what part of the world and what HF bands you listen to, but queen is used a lot by lots of amateurs.. the reason for the station not hearing me say my callsign, whether it was Quebec or Queen, was down to QSB.
@@TechMindsOfficial One thing you may wish to consider is language. Many non-english speakers learn just enough to get by with the basics of a QSO and learn the standard phonetics. I've spoken to many who get confused if you wander off piste. It's like CW, you don't listen to, and count, dits and dahs then convert them to the letter you listen to the sound they make.
how stupid the QSO, ask a few times to repeat call and then gave 59 sig report. How stupid. Antenna build looks very good, from 1/2" heliax. But real test would be set beside dipole.
I find the interest in small magnetic loop antennas baffling for anything other than just as a recieving antenna..The radiation resistance is sooo small that it cannot be efficient as a transmitting antenna especiall for QRP....What am I missing>
They in fact work very well provided they are optimised. The important thing is to balance area inside the loop vs current in the loop conductor while minimising Ohmic losses. Making it circular optimises area inside the loop and a circumference of about one eight wavelength gives plenty of current. Two turns reduces diameter that can be useful for covering lower bands, and/or intensifying magnetic field but reduces capture area. Inter turn capacitance can become an issue. Most designs settle for one turn and confine operation to 40m and above.
Peoples were used to say : Oh flying ? Nah, not possible. Now : it will NOT be the same as a classic and well placed dipole, no. If you wanna better energy transfer then you'll have to make it with a physical coupling and not the small ( 1/5 of the main loop ) loop but the downside is the noise, wich is bit higer than the small loop coupling ( of course the downside is bit less energy transfer but better "noise cancelling" . Gain ? The same, it will NOT gain as same as a well built and placed dipole BUT it's VERY silent and this let you listen the fleeble signar from far, far away... Try one if you can, trust me .
These are very expensive for what they are and perform worse than a random piece of wire and an LC tuner. We know this because a friend had one and did A B comparisons. The reverse beacon network also helped with the tests. His loops must have the worst efficiency of any loop on the market. The diameter isn't big enough and that normal air spaced capacitor will also be extremely inefficient. Expect between 1 and 3% efficiency. People say loops work, and yes they do, but a wire tuned with a simple LC circuit works much much better, and that's saying something. Don't waste your money people.

If you use the phonetic alphabet properly, you will find less retransmissions are required. I personally find Queen, Mexico, Kilowatt, Sugar and other non-standard words difficult to pick out of the noise.
Maybe you should not so painstakingly try to avoid mentioning pricetags. Its a lot of wasted time for people just to find out and research if they can afford an item. the antenna built by 2E0ERO looks outstanding and sexy. and i would prefer to support a small eruopean workshop (even if it is in uk who dont like rest of eu anymore) over a big firm from the states. UK > US - any time of the day (sorry yanks, but the us-definition of quality does not align with my stars, nothing personal) On the other hand.. its probably not in my budged do i even bother confirming that in an email dialog? probably not. Your channel would instantly become more useful to your viewers if you would not leave out the most important detail missing from all your vids i watched thus far :-) - subbed anyways, but i thought you needed to hear also the truth between all the well justified 'yesman' posts :-) 73 og4u
It’s not wasted time because prices will vary depending on your requirements. A simple email to the person making them will tell you how much it costs. :) thanks for watching, and yep, it’s an awesome antenna.

Seems to be okay for me. It’s not used much, but it appears to be online, I just made a post on there.

If you use the phonetic alphabet properly, you will find less retransmissions are required. I personally find Queen, Mexico, Kilowatt, Sugar and other non-standard words difficult to pick out of the noise.
NO NO NO NO, you don't use an ATU with a magnetic loop. The loop will not radiate properly if not tuned correctly and an ATU will not help.
I add a few NO NO NO NO NO's. that is a big NO NO to use a ATU with a loop, never do that
Actually, you're wrong. You can tune a loop with the capacitor and get the best swr you can. The ATU will then match the impedance.
Maybe you should not so painstakingly try to avoid mentioning pricetags.
Its a lot of wasted time for people just to find out and research if they can afford an item.
the antenna built by 2E0ERO looks outstanding and sexy. and i would prefer to support a small eruopean workshop (even if it is in uk who dont like rest of eu anymore)
over a big firm from the states. UK > US - any time of the day (sorry yanks, but the us-definition of quality does not align with my stars, nothing personal)
On the other hand.. its probably not in my budged do i even bother confirming that in an email dialog? probably not.
Your channel would instantly become more useful to your viewers if you would not leave out the most important detail missing from all your vids i watched thus far :-)
- subbed anyways, but i thought you needed to hear also the truth between all the well justified 'yesman' posts :-)

It’s not wasted time because prices will vary depending on your requirements. A simple email to the person making them will tell you how much it costs. :) thanks for watching, and yep, it’s an awesome antenna.
@@TechMindsOfficial i did contact him, and i found the prices to be quite reasonable.
The problem is more tolls and shippings after brexit.
Has the phonetic alphabet changed?

I think these are just way too expensive for home built antennas 🙄
