How to use a Magnetic Loop Antenna

Here I want to show you how to use a Magnetic Loop Antenna. I have enjoyed the walk during this beautiful spring day. This day has been windy so I would like to say SORRY for the wind noise at this video. I am working now on some good external microphone with the windproof shield ;) You can advise if you know some which is good for my Samsung Galaxy NOTE10+ with USB-C connector. I would be very thankful ;)
Stay safe and be healthy!
73, Paul.

Working phone QRP on a magnetic loop during a contest. This is the definition of Patience.

[@OM0ET]

I agree 😄 Unfortunatrly, there are running almost every weekend any contest. Contesters should leave at least a few kHz for non-contesters somewhere on the edge of each band free.

The 2E0 station will likely be on 50watts as thats the intermediate licence limit here in the UK. Love the channel, learned a lot.

That's amazing the contacts in 20 meters. I'm using my ML inside my attic on 27 MHz with very good results running 10 watts and make contacts with Poland and Greece. Sometimes the stations couldn't believe that I'm using only 10 watts inside my attic. So next week I'm going to the field. 7351.Using the same Way's to adapt the ML. Nice video.

Cheers!

[@mikepeirson1150]

Thanks for another excellent learning video (for me). I am a SWL near Dungeness in Kent SE England. I have recently bought an MFJ 1886 magnetic loop antenna. I have tried many different types of antenna in my time but getting two years off of eighty I want to make it a bit easier instead of climbing all around the roof etc. I have a small garden so no room to experiment. I have also switched my analogue radio to an SDR RSP 1A, so getting to grips with that as well. I live in a bungalow, and have set the loop on the mast about a meter above the roofline and fitted a rotator which I control from my desk to make things even more easier. I have set the rotator at 0 degrees facing north. Than means that at 40 degrees it will be at NNE and so on. I have tried in vain to find which way to point the antenna to start with or is it just rotate and listen and take notes?. The loop works good. I was thinking about making or buying a compass rose, look at what country to listen to and looking up the direction and then orienting the loop to that. On my old wire antennas I did receive a QSL card from the Marianas islands, and could listen to Radio Habana and many African stations. I am starting to waffle a bit here. All I wanted to know was where to start, which way to point. Thanks again, beautiful countryside as well.

[@tomcruiser2407]

Your video is as interesting as ever my friend, but I have long been interested in a correct comparison between an e.g. MP1 or another small vertical antenna when transmitting on the 40 m band.

[@thomasmaughan4798]

Loop antennas generate high voltage on transmit so be mindful of the power rating of the antenna. Expect about 1000 volts on a 100 watt rated loop tuner. For receiving they are ideal as they serve as a pre-selector for the desired frequency rejecting everything else; also rejecting a noise source through the axis of the antenna.

[@thestonerguy5276]

Thanks for another great video..and after watching you with with the X5105 I'm rethinking my continued use of a ft-817 👍

[@OM0ET]

Thanks! I had the FT817ND but I sold it soon. No ATU, small screen, small buttons, no good int.battery, no dsp, no CW/digi decoder, no PTT button, no int.MIC, no SWR graph.... all very important things in the field in one body 😉👍

Beautiful countryside. Great day for being outside. Enjoyed sharing the contacts with you, especially the number sequence contacts.

You can probably clean up wind noise with a high-pass audio filter around 60 to 100 hz. Thx for making the video!

Is that just public land, wow. Breath taking. What does the other smaller loop do? How did you know without looking you were close to the peak, listening for it to start fading? Each time you change the freq, you go thru that procedure or with different bands? Can the ATU be used to do it as well?

Well I have to give you credit--you definitely have patience and perseverance! By the way, have you operated the Xiegu5105 and a mag loop in digital mode with a portable computer--for example, while running WSJT-X or JS8Call? I would think that you'd probably have much better results?

[@OM0ET]

Thanks! 😊 the patience is very important when 5W QRP. No I didn't operated digital yet. This radio has an internal digi decoder but I didn't use it yet 😊 I am sure that also CW would be great but unfortunately I never learned CW before...

[@elmoreignacio8741]

Beautiful demo mate, and thanks for the video. One question though... when you tune in to a frequency, how far off it can you go before re-tuning your mag loop? Thanks and 73 - 4G1FBL

[@thomasmaughan4798]

It depends on band but these things are extremely sharp tuning and the lower the band the sharper seems to be the tuning. On 20 meters I retune if I change frequency by 4 khz or more. I don't retune just for listening, but once I find a station to work, retuning is more than useful. The system depends on perfect tuning to generate the high circulating current that generates the magnetic field. When tuned properly these things have nearly the performance of a well grounded quarter wave vertical, and they do not require a ground plane, nor would it help. If you have a strong signal that's more than about 20 khz away it will be suppressed and that's wonderful. By the time it's a megahertz away it won't even be heard.

Hi Paul, I have built a Loop antenna. My capacitor is a dual gang like your. Now I'm facing a strange behavior: after tuning the loop using nano VNA some time while transmitting the SWR go over 4. Nano VNA show a complete non tuned loop. Then play with capacitor position I'm able to tuning again .... I'm running 5W ... ... dirt between the capacitor plates? 73 iu2omt

Most probably it is dirt but also maybe max.power limit of your capacitor

Thans for the video. It seems you have quite a bit of receive bandwidth on that antenna, more than I thought was possible with a mag loop. I think I saw you move about 150 KHz without re-tuning. How much practical RX bandwidth do you have with this antenna?

[@OM0ET]

Hi John. The bandwidth for TX is not wide, maybe just a few khz. It depends on the band. On 40 is 5-6khz and on 10 is maybe even 20, but I dont remember exactly.

That little radio is not going to make many contacts with all those 100 watt and better stations running on the channel. QRP is to decrease power. Or ask someone if you should decrease power. At least in the States side that is the way the QR signals are.

SO that's typical high power stations, that can't hear much? too much emphasis on amplifiers and not on good receiving antennas, there is no reason that a station could not hear you. I don't understand the mentality of high power stations, that can be heard but can't hear anyone..
