Thanks for all your effort in the review. I've had a baby loop for a couple of years and my experiences match the review. I was able to test the loop at a couple of different locations in the yard and noted that the location and height made significant performance differences. I wound up reducing the height a couple of feet to improve SWR on 10 meters. I also painted it green to make it invisible against the pine trees. For me, well worth the effort and resources.

A friend of mine built a 10 to 20 Meter Loop which worked great on all five bands, it too had a very high Q, guess it's the nature of the Propagation Beast...However! The Tunable 20 to 150 Picofarad clamped plate capacitor could only handle 30 watts anything over that it was just a conductor....Thank you very much for this presentation. Well done 73's KC3ZDW

Hello Steve, as mentioned by many other enthusiasts you have made indeed a very comprehensive and informative video. Well done! I am a former user of the babyloop antenna and I used it intensely for many years with success. Later on I sold it to a very good friend of mine which I regret till this day. However it is my intention to buy the loop again since this is the most ideal antenna in my space limited situation. The most remarkable fact of your findings was, at least for me, that the babyloop in your situation was more sensitive for DX signals in the opposite direction in comparison what is explained in the antenna instruction manual, i.e. not in the direction of the gamma match but the other side. At the time I used the babyloop I was not aware of this property or behaviour I simply followed the instructions give by Cirro Mazzoni. I would like to you see, and with me many other radio amateurs I presume, If this also is also the case on your transmissions. Could you do some other experiments for us and share these with us? I would recommend you to make use of the Reverse Beacon Network or RBN for short. You do not need any additional equipment connected to your transceiver. You just use your computer to monitor your results. You only have to give CQ in { CW / RTTY / PSK31 or PSK63 } on a certain frequency repeatedly by sending the following sentence "TEST de G4HPE TEST". Make it last for a few minutes or so and observe your results on the RBN main page. Turn the babyloop in exactly the opposite direction and repeat the same procedure again. I am looking forward to you reaction ( and your findings of course! ) Sincerely Erwin, best 73 de PA3FCB

Excellent informative video. None of the other reviews I have seen have been conclusive. I have been looking at these loops for some time and you have persuaded me to buy. (2nd hand) I have small garden with a Hustler 6BTV. I can only deploy radials on a 45 degree segment. I hope that the Baby Loop will improve my reception.

@MrMesospheric 10 ай бұрын
Have you tried using more, but shorter radials for the vertical? Remember that almost all of the return current intensity is within the first ~10% of the radial's length; beyond that, it's largely a waste of wire and a needless feeling of constraint.

Well done Steve, a very detailed demo with some very good tips. I have a baby loop and a midi loop here. I did some trial tests on the baby loop over a 2 week period and was happy with the results. I used the keypad to alter frequencies and found the forward and reverse directions to be very similar in signal strength. I did some tests on the 40m band on our local radio club net and found the baby loop to be omnidirectional and and rotating the loop had very little effect. I assume that was because the radio club boys were within 40 Km of my location so I guess that means the 40m band NVIS propagation is omnidirectional and DX propagation or more directional. I added Fair-Rite mix 31 suppression torroids on all cables - the coax, the rotator cables and the DC motor cables. Those ferrites were added at both ends of each cable to ensure they were all adequately choked. I'm using the same rotor as you and I would be delighted if it would rotate at double the speed to get to the target direction quicker. Thanks again, 73, Jamie VK2YCJ

Good day Steve, thanks for the nice review. Due to the high Q of the antenna, I tend to tune the frequency of the antenna 1 kHz higher than the radio, when I'm in USB and tune the antenna 1 kHz lower when I use LSB. (I have the MIDI-Loop). I noticed that this gets my reading of the SWR exactly the same on the Loop-tuner and my TRX. On the part of issues with the tuning box of the loop, I recently got many times the fault: "Motor fail - no load". Initially, I checked all connections on the tuner, on my radio and on the antenna itself. I found some moist inside the tuning motor cable connection box, at the base of the antenna. It also partially corroded the wires of the connections there. I ended up getting rid of the terminal blocks there and soldered the wires together of the incoming and outgoing side of the RF choke that is housed inside that box. But it didn't solve the issue with getting "Motor fail - no load". Only after I swapped the + and - connection of the tuning motor, on the side of the "tiny little" plug that goes into the back of the tuning unit, it was solved. To this day (3 months later) the fault hasn't returned and I can enjoy the antenna again. 73 from Holland de PC7H - Roy

Well that was a surprise to find your video recommended in my KZfaq feed Steve. Your loop is certainly a substantial piece of engineering. My biggest problem is electrical noise to the front of my property where the shack is, whereas the rear is quieter. I do have a loop in the rear garden, but it is active RX only. A couple of thoughts, have you considered upgrading your stepladder? A more rigid set of steps is a definite plus. We have a set with yellow grp sides with aluminium treads, there are also a set of side rails that you can brace a leg against, they make quite a difference. I agree that your DC cable into that small plug on the back of the controller is less than ideal, if you are still concerned you could use six inches or so of a lighter gauge cable say 6A as a transition to the 40A. The impedance loss would be negligible, I’m sure it’s running on pcb tracks inside the box. Anyway an interesting video and good luck with your new loop. Excuse the strange KZfaq handle, it dates from when I had my big bike and I’ve never changed it. Cheers Nick G0OQK

Great video and demo, Steve. I bought a Baby-loop in June of 2022. I live in a small city and on a small lot. I wanted an antenna with the ability to direct the signal. I mounted mine on a Yeasu 450 rotator and started using it. I also found that the signals, both transmitted and received, are stronger off the backside of the loop. Glad to see that it wasn't just my installation. I've also tried it at two different heights based on the minimum and maximum distance recommended by the manufacturer. I have made numerous DX QSO'S with it. The noise level is lower than my 65' Windom and my DX Commander Rapide. 73, KC8WVG. Ciro Mazzoni should reference your video on their website.

I'm really very impressed! I'd be interested in your results on transmit. I have a fairly high noise floor on the lower HF bands and went for a Wellbrook RX loop as an RX only antenna with my TRX. Loops really do make a huge difference in noise floor - whilst the signal on the loop may be a couple of S-points down on a resonant antenna, the s/n is so much better that the actual strength almost is irrelevant compared to the vast improvement in listening experience.

What a wonderful review. Thanks. One question: When using the scope on the Icom in a wider view (like 250Khz or 500Khz), are you able to receive the whole spectrum, or is the filter so tight that you can't see adjacent stations on the scope?

I found this fascinating. Years ago I had a AEA Isoloop, a much more rudimentary system which had to be tuned manually and was very touchy. On 15m at least, it was quite effective. I wonder if the tuning process can be detected by nearby operators? I suggest that you may want to waterproof the front of the PL259. Water can seep through the threads. Usually I use self-vulcanizing rubber tape covered with a layer of vinyl tape to protect it against the sun, although probably you needn't worry about sun in the UK! -- 4X6GP

Hello Steve, this is by far the best video about this baby loop. Although extremely clean English is spoken. I didn't fully understand a small point because I speak German. If the antenna is in fully automatic mode and I scan the frequency for stations on the Icom with the VFO, the tuning of the antenna is also fully automatic, did I understand that correctly? Sorry if I'm asking such a stupid question?😢

Steve, at 5:20 min you are talking about the height the antenna should be above the ground. As an absolute newbie, I would like to know if this antenna is supposed to be mount more or less close to the ground (like in your garden), or if it is also OK to mount higher up, like for example on the fence of a balcony ~10 above the ground.

I'd prefer if you looked at weak signals as opposed to S9 stations. Also many get the loop for noise levels, especially on the lower HF bands, we saw no demo of this... Just an observation. I thought of getting the Midi loop, but jury is still out.

@MrMesospheric
@MrMesospheric 10 ай бұрын
Whilst a clear aspect is certainly important, height isn't for a magloop, and indeed works against DX performance in general. If you model one (vertically erected, as in the video), at 2m base height, you get a 'loaf of bread pattern', that covers all paths, long and short, fairly equally for the vpol radiation. There is somewhat weaker hpol radiation at 90 degrees to this. Take it to 10m, and it will reach much the same peak low angle radiation at 10 degrees (about -1dBi, but this value is likely to be significantly lower than for a real loop, as my WSPR tests tend to show). But overall, there is a loss of pattern at lower elevations at 10m, compared to 2m height and the NVIS increases by 5dBi at 90 degrees. So, unless NVIS is your quarry, a lower loop is the best all-round solution.

@MrMesospheric
@MrMesospheric 10 ай бұрын
I haven't quantified noise rejection (I never had noise!). But the pattern for the antenna gives you a rough indication: a figure of eight pattern, with vertical polarisation in the plane of the antenna, and horizontal at 90 degrees to it. The nulls in the pattern are sharp and deep. So there will be strong noise rejection within those nulls. Low-mounted loops (high ones are non-ideal electrically and physically) will have broad patterns and there's nothing to suggest this aspect would reduce noise.

I dont know if that paste is good or bad , I would put it together fluss, and then protect it from outside with silicone grease , and then service it from time to time. How is the loop reacting to heavy rain and snow with the non protected capacitor? How are the "nills" in and out of the plane? and are they also offset like the beam heading? Would be nice if the loop was offered as a raw loop , and then you could put together your own controller , eg arduino Just a thought, Tnx es gl
