HAM RADIO: 80M Band Wire Spiral Loop - Magnetic Loop, Small Gardens,

[@wino4340]

Nice work Mike....looking forward to its completion

[@mike-M0MSN]

Thanks 👍

[@gm4vyq]

Little trick to help thread wire through the holes - use toothpick or wife’s knitting cable needle and heat shrink it to the wire. It makes a handy needle.

[@mike-M0MSN]

great idea

[@j.franklin5327]

I really need a diagram, including the feed loop and capacitor, not so much the mechanics with PVC. Could you add it?

[@johng7rwf419]

Made similar for 14Mhz some years ago. It was very successful. Great video as always. J

[@mike-M0MSN]

Good to hear!

[@johnnorth9355]

Now this is very interesting as down to space limitations 80M is very difficult for me. Can't wait to see the rest Mike . 73

[@michaelm1keyhardy865]

Hi Mike, Another great build i was laughing when you fitted the black plastic caps on the pipe and you said Wonderfull like you were suprised.Mike M1KEY M0FCG

[@bobbyt2788]

Looking forward to the following videos! Got me really curious. Thank you for details.

[@mike-M0MSN]

Awesome, thank you!

[@SatansPooper]

you are a tease sir, I want part two

[@drewboy5215]

One of them will nicely on my garage roof Mike Keep up the good work mate , I’m looking fwd to seeing it working on the band 👍🏻👍🏻

[@mike-M0MSN]

Thanks 👍

[@ianxfs]

Looks like from the early days of amateur radio 👍🏻 I do like a cheap DIY store project too 😀 Roll-on part 2!

[@mike-M0MSN]

Yes it was! Cheers Ian.

[@m7nrt50]

Can't wait to the finished thing Mike

[@markg6jvy135]

Another good series and build 👍👏👏

[@mike-M0MSN]

Thanks 👍

[@aeron-mw7ofs]

Great stuff Mike, looking forward to the next part👍👍

[@4nk8r]

Looks pretty easy to do , looking forward to the next video . Cheers 🍻

[@mike-M0MSN]

Thanks 👍

[@J1mbo888]

Top Kitchen Video as always Mr Mike :-)

[@mike-M0MSN]

Cheers mate

[@wfwtheradioguy3414]

If you'd pull them wires a little tighter, you could have a small hex beam. 😊 Nice work, Mike.... Looking forward to part two.

[@mike-M0MSN]

Thanks 👍 lol

[@honeybadger6127]

is there a part 2?

[@billalderman4065]

Very interesting design ..thank you for sharing your wisdom..seen it can be made for 11m... Thinking this could be the best DX antenna to come along in a while ..⚡

[@Biagio918]

you gave me an idea I'll try to install a long wire in this way (spiral long wire) who knows if it works I have space problems

[@craigpalmer9196]

love your cooking

[@mike-M0MSN]

Thanks! 😃

[@ZL1BQDRoly]

Reminds me of the old AM receiver loops of days gone by.............

[@mike-M0MSN]

Hi Roly :) yep is does a bit 😊😊😊

[@raymondherringbotn172]

Nice. 👍🏻😃

[@mike-M0MSN]

Thanks 👍

[@littlebear5219]

Mike watch out for the spider!!!

[@mike-M0MSN]

lol

[@richardpowell723]

Thank you 👍 M0DSK

[@mike-M0MSN]

Welcome 👍

[@RobertJohnsonG0GFC]

Great work Mike, 80m at my QTH is a compromise to say the least. Waiting for the next one with some real time testing. Oh... what band was the one you gave Callum on Friday?

[@mike-M0MSN]

Same Band, for a different purpose (video about that soon).

[@mikesmithg0rfd356]

nice tennis bat

[@mike-M0MSN]

😊

[@markramsay6399]

Please tell me you are not drilling the holes using the kitchen bread board?! - Mike fab video, really love what you are doing here, fascinating and look forward to next video. Mark, 2E0MSR.

[@mike-M0MSN]

Yes I am!

[@Steve-GM0HUU]

If it helps, I estimated total wire length of loop to be 21.22m. Including the ends, maybe allow for 25m total? Looking forward to see this finished and how it matches.

[@mike-M0MSN]

Thanks Steve that's what I made it too. :)

[@olivierconet7995]

My EFHW is too short for 80m. Even if I could use it as a 1/4 wave for 80m, I will try this spiral loop. I like so much the old tube radio antenna it looks like 😁 Waiting for the practical result... Expecting to get away from EM perturbations thanks to its directivity. 73, F1SOC

[@mike-M0MSN]

Take a look at kzbin.info/www/bejne/m5yzZXxjfLeGgLM

[@woodybollox]

Hi mike. Is the next video about how to get it out the backdoor lol. Thx m8 👍

[@mike-M0MSN]

Yes, lol

[@ynot6473]

to aid threading the wire, drill the holes big enough to take a drinking straw. the wire has no option than to follow the straw, so push the wire through then pull the straw out.

[@mike-M0MSN]

Great Idea

[@patrickbuick5459]

Lol.. inwas looking for part 2 and then realized it was only uploaded a day ago.

[@mike-M0MSN]

Soon Pat soon

[@russozard2626]

hi mike interesting antenna project you are building what gauge wire are you using ?

[@mike-M0MSN]

Not sure of the gauge, maybe 19 or 22 it is .75mm

[@kellypaws]

Hold my glass of methylated spirits, this one's right up my street...

[@mike-M0MSN]

lol

[@kellypaws]

@@mike-M0MSN Still the most wonderfully chilled and relaxing voice on KZbin by the way. Love the videos.

[@sincerelyyours7538]

Looks great so far, Mike! 80M is impossible for me due to space limits but this antenna might just do it. How many watts do you expect it to handle in Tx?

[@mike-M0MSN]

I have no idea yet, I will test once finished

[@DonDegidio]

Hi Mike, Nice build. Don't know if it was mentioned, but are you using D10 wire for the loop? You and the family stay safe. 73 WJ3U

[@mike-M0MSN]

Yes I am, well DX10. Thanks Don.

[@TheBrynu]

i think this is going to be hard to tune mike because of it being multiturn loop and not single turn but good luck and i’m looking forward to part two

[@mike-M0MSN]

You maybe right....

[@Biagio918]

hi Mike I tried to make the antenna but with poor results that type of antenna needs a variable capacitor to tune it with the balun they don't work

[@mike-M0MSN]

We will see!

[@mevlutkc]

Is there an 80 mt antenna project with heliax cable?

[@W9HJBill]

Now to build a 160M spiral loop for top band. ;)

[@yl3amg277]

Will you be able to get the loop outside or it is meant to be a kitchen antenna? :D P.S. Nice job!

[@mike-M0MSN]

Eventually outside lol

[@bitemykrank1970]

I have a pile of 1m conduit lengths in the corner, and I have a bunch of wire left from undone and changed mind projects......I see a loop in my future....all I have to do first is paint the conduit bright pink, so it's not too obvious when in the air....I think two of these, a 160m aluminium 6 element flattop and maybe a 10 foot parabolic in the garden..seems a good idea to me....who needs to see the sky, it's always full of rain anyway. Look Honey, another antenna appeared overnight, but, I have NO IDEA where they keep coming from....

[@Steve-GM0HUU]

😆 I have also encountered this strange phenomenon at my QTH. Random antenna materialisation. Like molehills but in the sky. After some careful observation, these unexplained appearances do seem correspond with days when XYL is away from home. 🤔 Most strange - I shall keep investigating.

[@bitemykrank1970]

​@@Steve-GM0HUU Please do keep us informed of your progress in uncovering the culprit or culprits behind this phenomenon, which now seems to be a case of global skullduggery......I have come to a small hurdle with my efforts, it seems a field of T2LT's has sprung up on my back lawn, strange too, as they all seem to be different lenghts, seemingly 1/2-5/8th wavelengths on various HF frequencies, it's ALMOST like they were an intentional thing....most peculiar. I have asked my dogs, but both are tight lipped and have asked to see counsel.......I fear they know something, but are unwilling to grass.... the damn cat keeps looking at me in an odd fashion aswell....not surprised on that front though, he belongs to the missus, I think he's a spy.....

[@mike-M0MSN]

You Guys kill me 😊😊😊

[@stevec5000]

How did you come up with the design for this and why is it a spiral?

[@mike-M0MSN]

I didn’t it comes from an old 1930’s radio receiver antenna.

[@milwman1958]

I need a 6 m Halo that I can fit in a window. Can a verdant of this work?? it needs to be 49c tall to fit. KF0HRF

[@jgstevens5169]

Could I use this configuration for 11meter (CB)?

[@mike-M0MSN]

Yes but with a smaller diameter

[@MidlifeRenaissanceMan]

Duck duck go _66 Pacific magnetic loop_ There is a magnetic loop calculator for both Tx and RX An 11m loop only needs to be around 2.5m in circumference. Using some RG6, which you can often obtain for almost nothing, you’ll be able too make a reasonably efficient single turn antenna that’s good for around 80-100KHz without retuning

[@jgstevens5169]

@@MidlifeRenaissanceMan Thank you Chris for your recommendations. Need to give this a try. Seems to make sense to go this route verses a tall mono pole.

[@MidlifeRenaissanceMan]

@@jgstevens5169 I was using 8m of aluminium strap, and a home made motorised piston capacitor last night I mounted it on a 3.5m high push up lighting stand The noise on 40m was S3 vs my 12m trap vertical end fed half wave for 20/40m where the noise was S7 Almost no difference on TX, but so much easier to hear the stations

[@billellis5516]

What gauge wire did you use and how did you thread it thru the pipe

[@mike-M0MSN]

19 maybe 22 it is .75mm and by eye

[@dirkr7891]

for RX only !?

[@mike-M0MSN]

Yes and No Maybe QRP I will test once finished

[@franciscoalves5058]

works on 40m?

[@mike-M0MSN]

Maybe

[@adelarsen9776]

Either you have the radio bug or your don't.

[@mike-M0MSN]

Yep!
