I’ve built a few loops, from simple ones made from reclaimed RG6 and a toroid core ripped from a switch mode power supply, through to one made from 1” x 1/16” aluminium strap with a motorised tuning capacitor that handled 50-60W but caught fire when I gave it the full dollar :-) They are excellent and, elevated enough seemed to out perform my back yard verticals I have made from aluminium tube The narrow bandwidth keeps the noise levels down, and certainly removes broadcast band interference on the Pixie my son built :-)

I’ve been messing with mag loops the last few weeks with the intent to make a portable one.

Just curious was it your original idea or a remix? Would love a finer points build video and thanks for the video. 73

For the wingnut - get some brightly-colored nylon "mason line" at a hardware store and CA glue+tie a length to one of the wings. You can hold the line or loop the end around a finger while you screw it on/off to save it if you fumble your grip. It also gives you a fighting chance to find it if you drop it in the brush/gravel. Can also screw+CA tack a few spares onto some of the other bolt stubs if there's room. Good to have a fix right at hand when you need it. Learned this trick the hard way with some adjustable garden antennas...

Pretty amazing loop QSO!! TU!

Bravo Adam! Another super interesting antenna build you got here! Please do share the strategy for building and matching this compact magloop.

Great video!! Thanks so much! Here's another vote for build video, or two!!

Beautiful Job, Adam no doubt about it. This Mag Loop is definitly a burner. But If I tell you this true Story happened 2 weeks ago when I was portable out in the Fields. I was ear witness of a friend up in North Carolina talked to a QRP Station (0,5W) from England on 20m SSB. My friend up in NC State got the Big Ears with his beam antenna and the British Guy had a dipole antenna which I believe of a G5RV. Around this time it rarely happens that I hear UK Stations with even 400W of power. This Contact was phenomenal and my friend in NC was happy like a mike foxtrott. All I am saying is..."there's so much positive stuff and beautiful things out in this World no matter where you live or where you temporary are. People just need to keep their eyes and ears open to explore / experience them." Amen de DK5ONV

I'm certain good propagation conditions were in my favor and it was largely a matter of luck, but the antenna does radiate. It will never be as efficient as a dipole or EFHW, but sometimes the compromise of a very small antenna is worth it.

The high current exists everywhere in the loop; the actual feed is much lower in current. Of greater concern is the capacitor that sees the high current and thus also high voltage, but not so much at 5 watts. Also, "skin effect" is such that the current only flows on the surface of the conductor; that's why I and other use hollow copper tubing. it wouldn't use the inside anyway.

I never really liked the idea of magnetic loops because they are so narrow banded. However, this video made me realize that for something like SOTA, that basically doesn't matter because you spot yourself on a frequency and stay there. So it looks like I have a new antenna to research...

Do you notice any improvement changing the direction of the loop? Has anyone compared this to a budpole, or any home brewing of 2 hamsticks configured at a dipole at about 6-10feet off the ground? I can see this antenna as designed easier to transport. Just curious how it compares performance wise to other portable antennas.

Well, the noise floor at the upper west corner of the San Fernando Valley is pretty high.

I’m hoping to create a 2 m Multi element vertical dipole To use as a base station antenna at home I would like for all of the elements to be in phase so that they all radiate at the same time I just don’t know how to create the wiring harness to attach it all to get it to work correctly Any recommendations or advice would be greatly appreciated

I would love to see a build video for this! I would be curious to know how the use of an aluminum bar compares to using a piece of coax for the loop? I imagine both would weigh about the same as well as pack down easily. My concern with the aluminum is that it will oxidize with time and the DC resistance between segments may increase. Did you put anything on the segment joints to prevent oxidation or fo you clean them perioditly?

@K6ARK

3 жыл бұрын

The aluminum is much lighter. Measure the weight of about 10 feet of coax, and a frame to hold it up. I used stainless hardware to connect the aluminum bars and a little wiggling back and forth as I straighten the segments seems to make the contacts clean enough to prevent issues. Even after not using the antenna for an extended amount of time. I suspect you could also use some dielectric grease but I didn't want the sticky dirt collection involved with that. Minimizing resistance is key in magnetic loops, and I have no illusions that this loop is very efficient. But it's light, packs small, and it certainly seems to work well enough. There seems to be a good amount of interest in a build video, so it sounds like I need to order up some more material and make another. 😁

@NeWt0z

3 жыл бұрын

It's how much power is coming out of the antenna compared to how much your radio is putting into it. Different antennas have different efficiencies depending on what kind of metal it's made of, the way the metal is shaped, how much metal you're using, and a whole bunch of different factors. This antenna is a lot smaller than most antennas but what you gain from it being so small you lose in how well it transmits that power. This answer is not the most technical but I hope it at least answers your question well enough to understand.

@K6ARK

3 жыл бұрын

Yes, thanks Greg, that's a good simple description... The links in the description will give some approximations of efficiency for different size and dimensions of loops. Additional losses are incurred in points of electrical resistance like the joints in my accordion folds. With antennas everything is a trade-off. Size, bandwidth, and efficiency are 3 primary competing factors. Small transmitting loops (aka mag loops) are very small for the frequency of operation, and are actually relatively efficient radiators, but as a trade-off, they have very narrow bandwidth (high Q). And despite that relative efficiency, there comes a point of pushing too small of a loop too far, and losses grow.

Very Cool! For us instruction followers, (vs experimenters and innovators), what goes into "the box", and how is the Gamma match made? A video detailing the construction of "the matching box" and the gamma match components would be awesome. The remainder of the project seems very straightforward from a mechanical standpoint.

The idea is relatively simple. The capacitor tunes the loop BUT at that tuning, impedance increases as you work your way up either way from the feed point. So you want a 50 ohm point and it varies by frequency. That's why the alligator clip. Tune the loop for minimum SWR (maximum received audio noise) then move the clip for 1:1 SWR. Once you have found the sweet spot, put a mark on the antenna with a Sharpie or similar so you can find it again.

@@Brewerbill Ah, careful reading, I see. Yes, the exact nature of the tuning capacitor is crucial. It is common to use a "butterfly capacitor" because the relatively high RF current does not then cross a "wiper" or rotating contact. What happens is each side of the loop has its own stator plates and *between* them pivots the rotor plates and acts as the capacitance between the stators. Consequently a high RF current never crosses a wiping contact. There's a hidden benefit to butterfly capacitor; the rotor can be grounded! That means it can be used as part of the feed circuit. The shield of the coax goes to the rotor of the butterfly, and the center conductor goes *through* a smaller variable capacitor to one of the stators. Electrically it resembles a gamma match; but instead of an auto-transformer action, this works on the difference in capacitance which thus divides the capacitive reactance between the main butterfly and the matching capacitor and the whole thing can be at the low end of the loop. This is how the MFJ portable loop tuners work. You can see the schematic online for the MFJ 936B for instance. Conventional magnetic loops with a little induction coil can be difficult to achieve a perfect match. You can tune the loop easily enough but you cannot ensure a 50 ohm impedance. To achieve the 50 ohm impedance you have to tinker with the spacing and size of the induction or exciter loop and if it is high in the air, a bit difficult to reach! Capacitive matching eliminates that complexity, but at the cost of another variable capacitor.

@thomasmaughan4798

3 жыл бұрын

@@K6ARK The purpose of the matching capacitor is not immediately obvious since it *seems* to be in parallel with one of the main tuning capacitor sections, but in fact is is in series with the radio transmitter. When everything is in tune, the radio presents a 50 ohm resistive source without reactance; the matching capacitor is effectively in series with one of the sections of the main butterfly tuning capacitor. This creates a "voltage divider" exactly the function of a gamma match; but the gamma match relies upon inductive reactance and the capacitor match relies upon capacitive reactance. AT resonance it doesn't really matter! Initial tuning is NOT entirely obvious. You start with LESS matching capacitor and then find the strongest receive signal by tuning the main butterfly capacitor. When you have it, transmit a very low power continuous wave (I use "FM" mode on my transmitter) and adjust match for lowest SWR. Doing that changes the main tuning slightly, so you have to retune the main. With a bit of practice the procedure takes only a few seconds and the matching capacitor usually does not require adjusting within the band; only the main tuning capacitor. Being able to have the entire electronics of a loop antenna in a single box is hugely convenient. It means you can have as large a loop as you like and it can be highly irregular in shape if that's what it takes to make it fit. It makes it almost convenient to have several loops each optimized for a band, which is to say, the largest that you can make and still tune it. 20 feet of 3/8 or 1/2 inch copper tubing makes a great 40 meter antenna. Occasionally you'll encounter an amateur radio operator that thinks it isn't a magnetic loop antenna unless it is magnetically (inductively) coupled; but that is not the reason for the name. Magnetic loop antennas are named because they couple to the magnetic field of an incoming radio wave (or excite the magnetic field of an outgoing radio wave). Gamma matching and capacitor matching do create a DC electrical connection to the loop from the radio which in rare circumstances might be a safety consideration.

The primarily limiting factor for loops is the capacitor which experiences very high voltages. Because mine is built with 500v fixed value caps and a small air variable cap, 5 W is pretty much the limit.
