Having been restricted to static mobile operations recently for the Charlie Tango Sunday DX Net it was good to get out on foot on Beacon Hill, Leicestershire 248m 814ft ASL. The main reason to get out was to field test my recently constructed magnetic loop antenna. Right from the start of the walk the wind was causing problems with the sound on the video. Later on the summit with winds gusting ...
Portable Magnetic Loop Antenna for 11 Metre 27Mhz CB Band
Просмотров 105 тыс.10 лет назад
This is my magnetic loop antenna for QRP operation (4 Watts or less) on the 27Mhz 11 metre CB band. I had been looking for a lightweight antenna to use with my Midland Alan 42 handheld rig. The purpose of the antenna is to enable pedestrian mobile operation for the Charlie Tango DX Net held every Sunday afternoon in the UK. One of the options was a longer whip but I fancied having a go at makin...

My third Charlie Tango activation this time on Bardon Hill the highest point in Leicestershire at 912ft 278m ASL. This is also a SOTA summit - G/CE-004. Towards the tail end of the DX Mark 26CT037 (26TANGOMIKE037) came blasting in from 34 division on Lanzarote. I was not able to get back to him but Sid 26CT141, Michael 26CT1176, Gary 26CTX104 and Gareth 163CTX254 all had good QSO's with Mark. T...

This is my first RUclips video and my first Charlie Tango activation. I've regularly walked in the Lake District, Scotland and the Peak District but this is my first visit to Shining Tor. Contrary to what I said in the video Shining Tor is 559m 1834 ft above sea level. The road below on which the Cat & Fiddle Pub stands is the A537 not the A54 as I mentioned in the video. Please accept my apolo...
Will it be possible to e-mail me the blueprint plz

Hi matey. I am in Corby. I just love messing about with loop antennas. Not used mine up a hill yet as still experimenting. Had it over a year now and fantastic reception on the HF bands. Cheers from old George normally in garage. Ps not really much C B work so what's a good freq to listen too and uk time day etc.
New Sub here , Awesome build ! Would you mind sharing plans to build ?

Hello, I am 9TC829 In Windsor Ontario I have been watching people build Mag loops for a while now and stumbled over your Utub video. Great Idea.
Let me know length of radiotor

バリアブルコンデンサを入手できない。
Buenos días me podrías compartir las medidas de la antena para fabricarla gracias
Loops are simple but very effective. nice video
Thank you for the nice video. I always found descriptions for only reception mla
Exactly the wobbly "loop" shape construction i'd expect from an 11 meter band aficionado.
i cant log in on charly tango padge 21ct 003 björn
Great one! :)
A schematic would be nice - I couldn't quite understand now the little loop is constructed.
www.microfarad.de/magnetic-loop/
FYI "REF" stands for "reflected", not "reverse".
Part of the RF voltage may be reflected back from the antenna in a reverse direction. SWR is a measure of what is happening to the forward and reverse voltage waveforms and how they compare in size.
Good work! I have a homemade loop antenna, made from cooper tube (diameter = 3/8'').The diameter of this antenna is roughly 19 Inches. I live on the fourth floor in nine-floor house . The variable capacitor is an air capacitor (two sections) from an old radio.I connected the loop between 2 stators plates. I put ito my antenna 0.7W (27MHz).But.. unfortunately an reception range was only 400 feets. There is a heigh building (9 stairs) next to my hause.
At long last a CB radio enthusiast showing there's a world of aerial technology out there and showing how to pull it off.I made a spider antenna many years ago and was pleased with the results I Love the Alchemy of the art .:-)
HI 26-CT-3259 here I've watched your video recently and was wondering how you wired the capacitor im having trouble with mine its identical to yours and have had to change the capacitor as it only went down to 11.7pf so got another one which goes down to 6pf so is there a certain way to wire the capacitor many thanks 73s
SWaR. hmm, sounds like a bit of Boris Johnson sneaking in there. (or maybe FWaR!)
Who's he?
We call it S-W-R Like RCA or VCR or VHF We just say the letters.... Excellent demonstration of the build and I hope to replicate a version using 7' of 4" copper at 99% efficiency. 5k vario and the like. Thanks
Mag loops are great in noisey environments .I.e where there's loads of computers being used.(Noisy switch mode P.S.U,s plus computer transmission noise,Most urban enviro's).Get the outer loop to be as conductive as possible and make the coupling snug as a bug and Bobs your uncle and fannys your aunt. :-)
we call it whatever we like because we can.
It's the trick to take the loop diameter just right for the desired frequency. The radio capacitor should have low capacitance, of say about 30 pf max. That way, tuning should be more easy, and the antenna works better...
I find that size isn't critical (my wife would disagree lol). What is important is that the primary is 1/5 the secondary. For example a 4'' primary loop and 20'' secondary. A 50pf capacitor works great also. Experiment with round vs oval primary for more or less coupling.
Top video..!!!!
I am looking to buy a11 meter loop antenna .
Hello there go day now ok Williams lake ok cool. Ant sat .ant. sky ..scanner hdtv Ant .cancobra998@gmail.com .Cool. k
Good to see mag loops are alive and well on 11m and the Freebanders
How far can you talk locally with this?
It depends on a number of factors. To be honest since I built it I've hardly used it!
Congratulations for your work. I made a Delta Loop for 11 meters, 11,13 meters cable 4 mm 1,80 meters cable 75 ohms. So the Delta works fine in DX and local QSO´s. 7351. Tks, hope listen you on the air.
Thanks. The Delta Loop should be far superior to the mag loop. I have a half-size G5RV in the garden that works quite well.
Can you make me one. I will pay you for it
Thanks for asking, sadly I don't have time at the moment.
This breaks the terms of your licence
To what licence are you referring?
What licence would that be then paul c ?
Only directional antennas are not to be used for cb
Olá amigo você poderia me passar o diâmetro da bobina grande e depois da bobina menor para 11m
Info here - www.66pacific.com/calculators/small-transmitting-loop-antenna-calculator.aspx
Ele falou, 2m de fio 10mm, e o loop pequeno 1/5 do diâmetro do grande.
bonjour antenne loop pour le 27 mhz on peux avoir les cotes de l'antenne merci 73 14 cg 01

Swarr...????
The SWR is adjusted with the tuning capacitor and is low. A reduction drive, which I don;t have fitted to the capacitor would help set it with greater accuracy.
@26CT1445: As a HAM radio operator, I do know what SWR is (Standing Wave Ratio) and know the physics behind it. It's that I've never heard it called a 'swarr' before...
I'm a ham operator too, the word is a colloquialism used by the UK CB community.
Weird...
You could show the antenna in use with some rigs band 27Mhz. Would be great!
Thanks, there is another video where I'm using the antenna elsewhere on the channel.
Very good work!
I researched these and i was under the impression they are not very efficient, as in if transmitting on 5w's would be the same as on 3w's is this correct?
I found reception to be better than transmission. I would say if built correctly they are very efficient.
Nice video - have you seen a reduction in noise levels in comparison with a vertical antenna if you have used this at home?
The magnetic loop is low noise compared with a T2LT but since getting my ham licence I have not done any more experiments with the loop.
So the big question ,,,,how good is it
Pretty average to be honest.
Hi sir thanks for vid and explanation. If you were to put a tuning capacitor on a dipole antenna in an analogue way where should you place it and how would you connect it?
11 meters is supposed to be limited to QRP 4 watts AM 12 watts SSB in the United States, but we will always have those people who run 100 watt 10 meter radios modified to operate on 11, and the scant few crazies that run 10KW linear amps. Nice job, mate! Cheers, 73s KI7AQJ
I love QRP and especially when it gets DX
Looks like something you'd haul a floundering kid from a swimming pool with!
Nice!
10 Meter antenna build HELP PLEASE I built a similar antenna as the colossal 15Kw antenna, and see there i a capacitor on it? my question is what kind of a capacitor and how should it be connected My antenna is actually large copper radiator .64 wave calculated to half of that in hopes I get that little bump the .64 wave is know for! it is 1 1/4" copper to 1” copper to 1/2” copper radiator antenna pieced together. then the 8 radials coiled 10 gauge wire around fiberglass rods at 55% down slope. I will tune it for 50 ohms and low SWR But it is built tuff and am now looking to test with meters to see where it resonates, but thinking that it should have a static release the 8 coiled rods are attached to a 1’2” thick aluminum 7” diameter plate each coil is 103” long on a 4 foot rod and may ALSO BE MADE TO RADIATE? I intended to have this for ground plain only and have the aluminum plate grounded to ground rod I have driven 8 feet into the ground. some thoughts? static concerns? etc. thanks Geronemo in ND
does the capacitor size matter or would any size work
+R oh (thunder) Depends for which band you wish to operate. I have a loop that has a 30 to 250PF variable cap rated at 3kv and the loop is 3 feet in diameter. It tunes 40m thru 15m. It can handle about 35watts. Good luck.
+Sal Galvano i would be on 11m from 50 up to 100 watts
The value of the capacitor is determined by the frequency you want to work.
Wooh did not realise that the voltage would be so high on the loop. Any idea how much would be generated at say 100 watts TX ?
+fredintheshed1 Over 2000 volts RMS!
Yep the high Q equals 1000s of volts and 10s of amps. I bought some Comet 15KV variable vacuum caps (Swiss Made) for a loop antenna to run at 300 watts. I may try it at 600 watts, but I doubt it would handle my newest home brew linear amp.
Nice job ;-)
is it just me or is the audio volume fluctuating a lot between very loud, normal and soft? Im noticing this on quite a few youtube videos of late, so perhaps google has introduced some faulty agc into their player
+shriramvenu I haven't noticed it.
Nice location and video ambience intro, pity about the windy conditions does the TXCR have an audio output jack?
SW(a)R meter? local linguistics I suppose, down here most CB'ers called them SW(e)R meters much to the disdain of our resident Amateur Radio Operators. Good on ya' for having a crack at building something for yourself, thumbs up!
the magloop antenna will work better for ssb not so good for fm
I love this video . Lovely set up and nice chilled out style of presenting . 73
Looks to me it works fine!
