It's a known fact for us Amateur Radio Operators that the use of zip ties on any antenna projects gives us at least 3dB in extra gain. I enjoyed that one! :-)

I built a huge six-foot diameter Magloop and spent months designing and building the six-tube trombone capacitor! I used a hydraulic cylinder made from two pool squirters to tune the cap and remotely controlled it with a peristaltic pump. It looks very much like yours. I used a 1/5th ratio diameter piece of extension cord for the radiating loop and fed it directly with RG-213 coax. If all the math is right, it should tune from 80-10 meters!

Sorry, I helped "Uncle Reggie" build one of these but he soldered the center of the coax from the transmitter to the *_center conductor_* of the Faraday loop and had excellent performance. - I was surprised when I saw you solder *_BOTH_* the center conductor and shield to each end of the *_shield_* of the Faraday loop.

That will have a nice high Q factor on the lower bands and have a relatively good efficiency that size but not so on 10m like a true mag loop. High Q loop for 10m with 22mm pipe will be about 60cm diameter.

Inspires me to make a loop of smaller diameter tubing, but to fit the 3/8 24 thread of my CHA MIL matcher, so that maybe I can work a loop from 160 ~ 6 meters that I can turn vertical and horizontal. Nice video, kd8efq/73!

I've not really looked into a DIY mag loop. If you wanted to keep the kit more portable can you leave the joints un-soldered so you can break it down or would that negatively impact the performance? Thanks for the build! LCARA Ham Radio

@mike-M0MSN

Well the Mag loop works on skin effect so the joints need to be soldered so it appears to the RF as one piece, for portable use I would go for a Coax Loop, as this can be wrapped.. :)

You know sir the loop length is half wave dipole with out condenser at 27 Mhz so dipole resonance is equal to LC resonance

What is the polarity? Maybe both or even circular? Build a second and them with co-phase them or a 2 element yagi. Something to think about.

Dang, who has a radio that can tx on cb and ham to even needs a beast like that, when cb is scrap, separated, phone line or ethernet wire dipole length friendly? I really wish the FCC would open up the power and freq spread of cb, so it is not a threat to a hypothetical over power, out of band shack. That is also why people buy a cb, hear nothing, not even truckers, and show back up with a reciept, and swap it for gas.

Hi made one loop last week. Does not show any output in the VNA. In your video you have connected the shield on the loop with coax able which goes to the radio. In some of the literature they have left the shield as is and the live of the coax loops and gets connected to the shield.

Channel 40 in the USA is 27.405. Center of the band channel 20 is 27.205 and channel 1 is 27.96. Must be a little different where you are. Mike did you ever add the capacitor to this one? I just watched the dual capacitor 40 & 80 Meter loop but didn't know, perhaps that was a separate build from this one?

27.5 not a lot of us, HOWEVER, if it's diameter was reduced by a few % could it not be made Nativity Resonant on the Ten Metre Band 😉

Hey, i don't think that is a magnetic loop. You got way above a quarter wave sizewise and so made it cross the selfresonant point and so got rid of the advantages of the "magnetic" part. I am not super sure, nor do i want offend, but what you build here is not a Mag Loop for 11m band. It's more a quarter to a halve wave antenna. What you basically did is get the Z way lower than Xc , that is not how magnetic loops work. Maybe i am wrong. Enlight me please :)

It is NOT a good idea to perform soldering with tin. You should use copper and silver bars to solder all tubes to avoid RF loss.

Never mind the loop just add a bit more to the fry up and go into competition with Gordon Ramsey ! Stop Press - price of copper pipe goes up due to unusually high demand :-) .
