What is the job of a BALUN in a HAM amateur radio system??
And do all Baluns fulfil this job in the right manner?

[@lookfrosty]

Sensational video. Thank you so much for taking the time to explain many aspects. You've greatly helped my understanding on this topic.

[@HitchHiker4Freedom]

Excellent series. I'm back watching them a second time as I watched it last year. This year I want to make a 1:1 balun to use on my 11 meter Moxon antenna. Thank you for taking the time to teach us.

[@videoric]

Fantastic video! After many other videos and reading a dozen research papers on this, I finally am beginning to understand it because of you. You showed me visually what I couldn't put together from the written words with an excellent presentation. The best thing of all, however, is that you seem like you are having fun, and I love that. Well done and I thank you for the time and effort you put into this.

[@pda49184]

Thank you ( danke) Peter.. A lot of questions answered an a few remaining. Excellent presentation..

[@albertvanduren1693]

Thank you for the clear and thoughtful explanation. Your ability to combine theory and practice is excellent!

[@spib65]

Many thanks Peter, a superb video, and something to learn from, 73's! and hope to catch you on the bands one day.

[@matthewmcintyre5034]

Exceptional tutorial and walk-through! I wish I had found this sooner. Thank you!

[@karlke0jwk368]

By far the best BALUN video that I've seen. Totally nailed the explanation of what the BALUN is actually for and how to measure it. Thank you for putting out good thorough information. Now on to part 2.

[@MrCarlsonsLab]

Great Balun video Peter. Love the high energy into! :^) That miniVNA is a neat piece of test gear. All my thumbs point upwards!

[@TRXLab]

Thank you Paul! Yes the miniVNA is really neat. Now there is a new version on the market which goes up to 3Ghz. 73

[@samiam5557]

Looking forward to part 2! Very informative look into the mysteries and magic of 'balun' world.

[@TRXLab]

Already in production Sam! Thanks for watching 73

[@andresgongoraYT]

Danke! The Balun video-series I was looking for :)

[@Joe_KS1I]

Excellent presentation Peter. I actually learned something. Thank you very much.

[@nlo114]

Excellent presentation thank you. Now I understand, I can go ahead and build my 'small' magnetic loop antenna coupling coil with better balance than planned, and lower noise. Thanks again!

[@davideisenberger6197]

Thank You Peter! I love your videos! I have learned so much from you..

[@TRXLab]

Thanks for watching David.. 73

[@davelister796]

Fantastic video! Thank you! Now I'll watch part two, for the rest of the story.

[@TRXLab]

Thank you Robert! 73

[@DavidVine-DOCVIDPRO]

I seldom have full confidence in KZbin tech vid info but this maker inspires confidence that he knows what he's teaching. Also, he goes slowly and methodically providing very good instruction.

[@joshtam58]

Freaking fantastic. Nice to have someone explain the why and the how...not just "do this because everyone says do this"

[@OldSweetTed]

Peter: I actually understood this information! I look forward to the other videos and learning about baluns and toroid use. Thank you for your effort!

[@TRXLab]

Hi Jim, thanks for feed-back glad that you like it 73

[@watsok]

Let me join in with many others to say this is the best description and examples of what a Balun is and how it should work that I have seen. This should be the first video anyone watches to understand these devices. Thank you for all your efforts and youtube videos. K1KLW

[@TRXLab]

Thanks for the kind words! 73

[@gregtreble9086]

Great video Peter and look forward to seeing further video information....Thank you for all your work! 73s Greg VK3KV

[@aeromech8563]

Fantastic and easy to understand great video keep them going 👍

[@aerofart]

If a picture is worth a thousand words, then a TRX video series explaining BALUNS and chokes is the mural of the Sistine Chapel, and many of the explanations presented elsewhere are simply cave paintings. Thank you for bringing an EE analysis to the table, TRX. Your channel is one of the best out there, alongside W2AEW channel and The Signal Path channel.

[@wntu4]

This one video taught me more about this subject than everything else I've ever read or seen. Very grateful to you.

[@TRXLab]

Glad that you like it David! Thanks for watching 73

[@phoebelala]

Just to add my thanks for your effort and obvious enthusiasm in helping folks like me to further our knowledge. Much appreciated, now to watch part 2

[@TRXLab]

Thank you! 73

[@glaros0]

Very useful video, I took notes for many aspects you've mentioned. Thank you very much Peter. 73, Kostas

[@TRXLab]

Thank you Kostas, glad that you have a use for the video... All the best 73

[@acestudioscouk-Ace-G0ACE]

Thanks for explaining this. I'm not very technical so this helped me a lot.

[@KB5PQL]

Perfect timing! :) I've been researching building one! Thanks!

[@TRXLab]

Very good! Good luck with the project. Thanks for stopping by 73

[@dennisqwertyuiop]

Great information, and taking much time and work for this video thank you Peter

[@TRXLab]

Thank you Dennis. Yes you are right this kind of videos consuming a lot of time until it can be uploaded... All the best and 73

[@jboutdoors5181]

Vielen Danke fur dieses Video machen! Es war sehr informativ und Ich habe viele gelernt!

[@stephane-710]

Thank you very much for this great video ! I was looking for more explanations concerning de Baluns since some days... you did it ! I will continue with your next video. Vielen Dank und Grüsse aus dem Elsass !

[@norbertstepien9185]

Excellent video and analysis. Thank you.

[@sdgelectronics]

Thanks, really interesting video. Look forward to the next part.

[@TRXLab]

Thank you Steve! By the way could you please check your massage in box. All the best Cheers

[@JarlSeamus]

I finally understand what a BALUN actually is and what it is supposed to do. This was always a washy concept for me. Seeing the broadcast amplifier added to the description makes all the difference. Danke!

[@AlbertMilliron]

I wanted to thank you for this video. I had a balun on my loop antenna and had problems. I measured my loop for 3.55 mhz since it’s harmonics would be 7.1, 14.2, 21.3, 24.85 and 28.4 Mhz - I had very nice swr on all bands except the primary frequency. I did everything, shortened the antenna, lengthened the antenna. Shortened the ladder line, lengthened the ladder line. Increased height… basically everything but couldn’t get swr down to a reasonable reading on 3.55 mhz. After watching your video, I then looked at my balun. I had recently bought a VNA and found the balun had swr issues on 80 meters. All that work on the antenna for nothing. One top off was when I put a length of 75 ohm coax then to 50 ohm, the swr went down, but I wanted to use the loop on all multiples of the frequencies… so all this time, it was the balun. The balun said it was rated from 1.8-30 mhz at 150 watts. Well, this well known companies 4:1 balun didn’t work in the lower bands. With VNAs becoming within nearly everyone’s budget, those companies who rate their Baluns will now have hams looking over their shoulders. I built my own balun according to your other videos and now the loop works fine. Thanks again for your instructive videos…. De AL7KT

[@TRXLab]

Thank you John, that was my intention and I'm glad that it works! 73

[@larryk4mu240]

Hi Peter, another one of your great videos. I Enjoyed it. This is one of those videos you watch more than once. Great subject you picked for this one. Will wait for part two. 73

[@TRXLab]

Thanks for the kind words Larry! 73

[@moonies123]

Fantastic videos every time. Thank you so much for sharing your knowledge with the world. VK7HCK 73’s Con

[@radioman4738]

This video is very detailed and explained in a great amount of time as opposed to other videos on youtube. I know that it will take more of my time to watch the video but for sure I will learn much more then what a short video has to offer. I enjoy the mild manor humor and even the slight mistakes of camera use as it is in the real world. Pleas know that your videos are much appreciated among the new and old "HAM" radio community. There is always something more to learn that we may have over looked or very simply have not had anyone else to teach us as in my situation. I look forward to viewing as many of your teachings and explanations about electronics as are available. 73 from VA3ACJ

Thanks for feed back Hussain... 73

[@acestudioscouk-Ace-G0ACE]

I'm watching this series of videos for the second time because there is so much good stuff to learn, I need to watch it at least twice to take it all in. You have put a lot of work into this and I'm very grateful. I wonder how many people you have saved from radio interference and how many rigs you have saved from too higher SWR! Thank-you.

[@PapasDino]

Thanks Peter, very useful. Look forward to Part 2! 73 - Dino KL0S

[@TRXLab]

Thanks Dino the next video is already in production.. 73

[@iw0hex]

Waiting for part #2 , Peter. Compliments for 100 videos !!! :-)

[@TRXLab]

Thank you Pasquale!! Part 2 is already in production 73

[@f.allenrisler5303]

I have seen a few other videos on this topic but none were as awesome as this 2 Part Series. Finally someone actually explained the concepts of why it is needed and why some designs are better than others. I have seen some videos that probably don't really work this well because they did not test them. I would like to see Part 3 where you finish the balun and show it mounted and connected in the box with some design elements to consider. Meanwhile please show me a picture of it with the cover off. Thanks!

[@mikesradiorepair]

Great explanation Peter. Looking forward to part 2. That's one thing I have never done is wind my own Balun. Always used commercially made ones. I'm tempted to test them and see just how well they actually work. Mike

[@TRXLab]

Thank you Mike. Yeah you have all the needed test equipment to test them. Curious how that turns out... All the best 73

[@np3jd37]

Thanks for going far and beyond explaining all this material. 73

[@TRXLab]

Glad that you liked the video!

[@mrkattm]

Peter another fantastic video, perhaps the best handling of this information on the internet that I have seen! Again very timely, I was doing almost the exact same experiments last week trying to really understand how Bal-Uns work. There is so much information on the Internet and lots of it is just wrong or they make it way too complicated. You presented and walk the viewer through it perfectly and again I felt so smart knowing what and where you were heading and I learned something too... I can't wait for you next video, take care!

[@TRXLab]

Thank you Michael, yeah it is funny that my videos are always just in time :^) All the best 73

[@askthebuilder]

Very very good video. MANY TNX for making it. I've got hundreds of videos here on KZbin and I'm sure you've discovered it's best to IGNORE the A * * HAT comments. Many of us really appreciate you sharing your knowledge and curating it here on KZbin.

[@TRXLab]

Thank you very much for feed-back! Glad that you like my video! Of course you are right we have to IGNORE those comments. Thanks for stepping in 73

[@askthebuilder]

You're most welcome. 73 de W3ATB I need every video you can make about all things baluns and antennas. There are many who are very very grateful for your investment of time and you curating your knowledge.

[@TRXLab]

Thank you Tim. Well there is a lot of stuff already here on my YT channel and even the balun series is 4 parts and one more is in production. If you like you can link my videos on your channel....Thanks again an have a nice week 73 de Peter

[@charlieoscar09]

Thanks for the video Peter very well done and explained.

[@TRXLab]

Thank you so much. Take care 73

[@AntiqueRadioandTV]

Just wanted to say thanks Peter for this fine video on Baluns. I learned more than I ever did before about these mysterious "creatures." I am really looking forward for the next video to see how you come up with one with both good swr and proper reduction of common mode current as well. A good trick I would say. I would also love to play with one and see if I could be successful as well. Very, very interesting and Good luck! 73s Tom

[@TRXLab]

Thanks for the kind words Tom. Always glad if my contest is of any interest. All the best Cheers

[@moonies123]

Nice video, Peter I made the same spiderbeam Balun like that one. I used the same size core, but used a good quality rj58 mil spec coax for my homemade spiderbeam antenna. It works well the Balun, no common mode currents.

[@fotografm]

Excellent video. I learned something !

Great explanation, thank you for your videos.

[@CoroPlanesLLC]

I have been an operator for about 16 years. I am only now beginning to learn about Balun and how and why it works. I want to say thank you for taking the time to put the videos online to help everyone learn about an important but often ignored aspect of our hobby. Good Job!

Thanks Peter, finally, I understand this test method!

[@weslindsey]

Great video. Thank you!

[@Satchmoeddie]

Another great video, and it debunks a lot of the claims made about overpriced junk products peddled to unsuspecting hams. I looked for that VNA & found it was sold out in 2014 and they are not making anymore of them. I found another similar kit on eBay that has good reviews on eHam for whatever that is worth. If I get lucky, I might make enough betting on the election to buy a nice comm monitor. & spectrum analyzer. I started buying Amidon cores some time ago and witch wind my own Baluns, and Ununs. I am so happy you are going into some depth on the theory of functional working baluns! Thank you again, Peter! I was out of town on July 2, 2016, away from the internet & television. I did find a lovely old WWII transceiver, and the dynamotor power supply, complete with 1942 211 valves! My uncle wants me to take it home, so in January, I will bring it back with me. Gott Segne 73s!

Thank you for this entire series Peter! Please ignore anyone who either A) criticizes your English or B) says that the videos are too long. English is a goofy language, and yours is as good as most native speakers. As for too long; well there are fast forward buttons - but as yet there are no "please show me more details" buttons on KZbin. Always best to put it all in there.

[@TRXLab]

Thanks for feed back and all the kind words Matt! All the best and 73

[@justincase3880]

Good points made. However, the 2nd & 3rd examples are “chokes” (not impedance matching transformers) .. but, good “partial” info for a center fed dipole. Also, End Fed Half Wave antennas require a 49:1 “step up”/ 50 ohm to “high” impedance (about 2400 ohms or so) match. Hence, the primary and secondary need common ground (and usually/likely need a “choke” to block common mode RF current on the feed line).

[@mabo4848]

Danke ! Super Videoreihe !

[@martinda7446]

Just wonderful, quality content and entertainment. Also, I'm sure you will not mind, I loved the pronunciation and was laughing at the 'Balloon' (which is what we have at parties of different colours and blow up with air). 'Bal' (as in balance) and 'un' (as in under). Its such a trifling thing, and I was wondering if I should even mention it, but I wanted to say thank you anyway, so it was an opportunity. On second thoughts please keep saying balloon.

Excellent video, Peter. I have, over the years, built my own common mode chokes, and, like you, stand on the shoulders of the giants. 34 years of RF construction and still learning, it's nice to know there are still guys out there willing to take the time to teach the new-comers to RF construction. Thanks for the IC-7100 ALC modification. That was well thought out and, the modification works very well, though I now tend to wind down the output to 100 Watts. Don't want to be greedy, eh. Looking forward to the next episode. Cheers... Tony g6ypk

[@TRXLab]

Thank you Tony! Yeah If I have seen further it is by standing on the shoulders of giants. That is how scientific works... we learn more any new day. Thanks for stopping by. 73

Love to see someone actually doing important measurments. I'm so tired of only SWR being measured. Now I need to find out how to do this 1 with the TinySA 2 with the NanoVNA if possible.
