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.
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.
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.
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
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.
I seldom have full confidence in RUclips 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.
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 RUclips. Always best to put it all in there.
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
Very very good video. MANY TNX for making it. I've got hundreds of videos here on RUclips 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 RUclips.
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.
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
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 !
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!
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!
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
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!
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
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
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
Thanks, Peter. Keep up the good work. I'm about to give a talk in 20 minutes to the radio club on construction and theory on common mode choke/ baluns. Regards ..Tony g6ypk
Thank you Peter for making radio life interesting. You speak great English and explain complex subjects very clearly. Keep doing the videos because they are most appreciated. 73 de GI8WFA.
I am just starting to learn ham / amateur radio hobby. Your video is super and very informative, I had learnt heaps and loo for to the next video. regards Rick, ham radio student.
Now this is the part of radio and antenna's that I find really fascinating.....Many thanks for this Peter and will be looking forward for part two......73....
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).
If you want to get the pronunciation down exactly, it's bal-un, or multiple bal-uns. Your'e such a delightfully charming person, I really don't think that it matters. Thank you very much for being so instructive and having us all visit with you.Verend
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
Really thank you TRX Bench for your video. This is something all new hams ought to see and assimilate. As for the pronunciations Balloon or B al un, who cares? We ALL did understand what your are talking about. Let's try guys not to concentrate on this little word but appreciate the real good explanation. Thumb up for me. 73 Daniel, IK2SGL/OA8
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!
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.
Peter thanks for the tutorial. Not sure I fully understand how baluns work. Probably need to watch the video again a few times. Looking forward to watching part 2 though. Robert.
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.
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!
To the grammar police. How's your German? For us that are new and even those that are not, this is an excellent video. 10/10. Explains very well and a lot of education in very short time. Why disrespect someone who is so generous to help others. Not cool. Maybe he should post in German so we can see how well you do interrupting for us.
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
Nice video Peter. After looking again, the connections are clear. They weren't because some soldered points covered the hot wires. One more question: the two common mode signals are connected to the primary winding. But then you don't have a primary current, do you? In that case: how can the balun generate a secondary winding current / voltage? Or are we dealing with a capacitive coupling i? My former question: The connections of the measurement setup are not clearly visible in the video. Could you provide a schematic of it? And an explanation based on this diagram would be very welcome. Thanks in advance and all good wishes for 2021!
Will be waiting on part 2 Peter. I need to build a new one for my Hygain TH6DX. The one on it is about to fall apart due to age. Very nicely done my friend. Thanks for sharing as always. 73 Buddy
Will be waiting to see it Peter. I went up on the roof yesterday and the wiring on mine is old and cracking up. It was only designed for 200 watts when I built it. At least it is easy to get to. This monster antenna weighs in at 95 pounds (43 kilo's)
yeah to heavy for easily take it down. It that the antenna on your tower behind your house? Well the Balun I will demonstrate will be good for minimum 800 Watt. Take care bro 73
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!
Hi, I really enjoyed this video series and has helped me a lot. Your friends design on the 12 turn 1:1 torroidal balun is the one which I will be using on my hf antennas in the future.
200 ohms represents a OCFD at about 40 feet in height, if the height of the antenna changes, the impedance changes, so it is the height of the antenna that determines what type of balun you would use. The 4:1 if typical for most antennas, so that is why it is so common. Some antennas require a 9:1, or 1:1, it all depends on the antenna, and how it is installed.
22:47 It isn't easy to see at this angle but would I be right in thinking that the output of the balun (the green capacitors) is only connected to the core of the coax? Also, the colours on the resistors are difficult to identify (for me) so would it be possible to know the values of the resistances on this very useful looking test circuit? Thanks!
The green objects are 100 ohm resistors (brown black brown), not capacitors and they are on the output of the balun for matching purposes. There are two sets of parallel resistors on the input side. They each are a 27 ohm resistor (red violet black) in parallel with a 330 ohm resistor (orange orange brown). The equivalent parallel resistance is about 25 ohms (24.96).
And YES, i find all your videos are be great. Und wenn das Englisch nicht gut sein sollte, dann eben auf Deutsch, ich finde alle deine Videos großartig!
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.
Thank you for the clear and thoughtful explanation. Your ability to combine theory and practice is excellent!
Fantastic video! After many other videos and reading a dozen research papers on this, I finally am beginning to understand it because of you.

Freaking fantastic. Nice to have someone explain the why and the how...not just "do this because everyone says do this"
Excellent video and analysis. Thank you.
Great information, and taking much time and work for this video
thank you Peter
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
Great Balun video Peter. Love the high energy into! :^) That miniVNA is a neat piece of test gear. All my thumbs point upwards!
Thank you Paul! Yes the miniVNA is really neat. Now there is a new version on the market which goes up to 3Ghz. 73
Exceptional tutorial and walk-through! I wish I had found this sooner. Thank you!

This one video taught me more about this subject than everything else I've ever read or seen. Very grateful to you.
Glad that you like it David! Thanks for watching 73
Many thanks Peter, a superb video, and something to learn from, 73's! and hope to catch you on the bands one day.
Fantastic video! Thank you! Now I'll watch part two, for the rest of the story.
Thank you Robert! 73

Sensational video. Thank you so much for taking the time to explain many aspects. You've greatly helped my understanding on this topic.
Thanks for the video Peter very well done and explained.
Thank you so much. Take care 73
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!
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
Thank you! 73
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.

Thank you Mike. Yeah you have all the needed test equipment to test them. Curious how that turns out... All the best 73
Thank you! Very good video! Love your accent, and regardless of how you pronounce Balun, you are very understandable!

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!

Thanks for the kind words Tom. Always glad if my contest is of any interest. All the best Cheers
Nice video Peter.
After looking again, the connections are clear. They weren't because some soldered points covered the hot wires.
One more question: the two common mode signals are connected to the primary winding. But then you don't have a primary current, do you? In that case: how can the balun generate a secondary winding current / voltage?
Or are we dealing with a capacitive coupling i?
My former question:
The connections of the measurement setup are not clearly visible in the video. Could you provide a schematic of it?
And an explanation based on this diagram would be very welcome.
Thanks in advance and all good wishes for 2021!
Many thanks this is very interesting indeed. I'm now getting the gist of this subject.
Glad that you like it. Thanks for watching 73
Very fine informations about balun, great thanks to you, best 73 F5HUP
Will be waiting on part 2 Peter. I need to build a new one for my Hygain TH6DX. The one on it is about to fall apart due to age. Very nicely done my friend. Thanks for sharing as always. 73 Buddy
Okay then we need to do it double as good as planned bro ! :^) Thanks for feed back my friend 73
Will be waiting to see it Peter. I went up on the roof yesterday and the wiring on mine is old and cracking up. It was only designed for 200 watts when I built it. At least it is easy to get to. This monster antenna weighs in at 95 pounds (43 kilo's)
yeah to heavy for easily take it down. It that the antenna on your tower behind your house? Well the Balun I will demonstrate will be good for minimum 800 Watt. Take care bro 73
It is on a 25 foot telephone pole. I have a platform under it so I can work on it when needed. Will be waiting for further videos my friend.
Thank you for your great effort.
Danke! The Balun video-series I was looking for :)
Very nice video, and as always explained very good, thank you.
Glad that you like it, thanks for watching 73
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!
Hi, I really enjoyed this video series and has helped me a lot. Your friends design on the 12 turn 1:1 torroidal balun is the one which I will be using on my hf antennas in the future.
Thanks for feed back Danny! 73
Excellent video. I learned something !
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!
Hi Jim, thanks for feed-back glad that you like it 73
200 ohms represents a OCFD at about 40 feet in height, if the height of the antenna changes, the impedance changes, so it is the height of the antenna that determines what type of balun you would use. The 4:1 if typical for most antennas, so that is why it is so common. Some antennas require a 9:1, or 1:1, it all depends on the antenna, and how it is installed.
Very informative, thank you for the video.
Thanks for watching 73
22:47 It isn't easy to see at this angle but would I be right in thinking that the output of the balun (the green capacitors) is only connected to the core of the coax? Also, the colours on the resistors are difficult to identify (for me) so would it be possible to know the values of the resistances on this very useful looking test circuit? Thanks!
The green objects are 100 ohm resistors (brown black brown), not capacitors and they are on the output of the balun for matching purposes. There are two sets of parallel resistors on the input side. They each are a 27 ohm resistor (red violet black) in parallel with a 330 ohm resistor (orange orange brown). The equivalent parallel resistance is about 25 ohms (24.96).
Excellent presentation de N9NY
And YES, i find all your videos are be great. Und wenn das Englisch nicht gut sein sollte, dann eben auf Deutsch, ich finde alle deine Videos großartig!
Great as usual! Now on to the next part! About to build an 9:1 unun, so maybe I'll do it the right way after watching your videos. Thanks!
Thanks for watching Jack 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.
Great video. Nicely done. Barry, KU3X
