Baluns & Ununs - Understanding Their Role in Antenna Building

[@Hebdomad7]

This is the stuff every other Armature Radio KZbin channel just glosses over because they think it's common knowledge without thinking of the newbies trying to get into the hobby. Thank you for explaining things in simple terms beginners can understand. This is also the best video I've watched on the subject! I didn't get into armature radio to nerd flex on other nerds. I'm into armature radio because I'm legitimately excited on how it all works. We all want more people to play radio with. Thank you again for helping more people get into the hobby.

[@KG-xf9ew]

Nerd flex - excellent and absolutely right.

[@alexkram]

not to nerd flex but armature doesn't mean what you think it does

[@stiantjensvold6624]

[@stiantjensvold6624]

@@RichardEnglander Trust me, the day i pass that exam, you will know it... im getting more and more correct answers every time i fail, so projections are I'll pass some time in the next decade :(

[@bodstrup]

Thank you, first time I think I understand the difference between UNUN and BALUN. I get lost quickly when David Cassler starts drawing on the whiteboard giving likely correct but very complicated answers to simple questions 😅

[@COASTALWAVESWIRES]

Thanks for the great comment! That’s exactly what I was referring to 😂

[@Frisky0563]

Agree with you I don’t care much for Dave. I just can’t relate to him, no disrespect

[@mewintle]

Different learning styles. I need to have the “why” stuff to internalize information. But I understand that most people learn better with technique vs theory. So this video left me unsatisfied. But it works for many (most) people. Awesome that we have so many Elmers right here in one place (KZbin)!

[@WR3ND]

@@Frisky0563 I like Dave. He's like a gnome in his workshop trying to explain the hardships of Santa to the elves. Honestly, I mean that in a good way. But yeah, he talks in his language from his perspective. I have noticed that sometimes even he isn't technically correct even if in a practical sense he is. I think it comes down to what people are familiar and comfortable with. I like gnomes. ☺Cheers.

[@WR3ND]

@@mewintle I'm the same way in needing to know the why and how of things for them to fit and stick into their place in my understanding of things to see and figure out how things work in relationship with each other and what needs to be done when. While it isn't perfect of course, things such as the water analogy for electrical circuits have gone a very long way for me. Taking that further, RF is perhaps a bit like sonar... 🙊Cheers.

[@ky4rod]

Great explanation Walt, concise and to the point to help beginners understand the fine points of antenna building. This is why I really like and recommend the videos on your channel. Also that's a nice Hammarlund in the background, I have an HQ-160 that I have had since my teen years in the mid 1970s! I started out with it listening to shortwave in my teens and it stoked my interest in ham radio.

[@COASTALWAVESWIRES]

Thanks! I was heavily into shortwave in my teens as well. I got that HQ-180 by luck a couple years ago. My neighbor across the street found it in his attic and gave it to me.

[@redstickham6394]

I did SWL as a teen as well using a Heathkit. It later got me interested in ham radio as well.

[@tomdonahoe3539]

​​@redstickham6394 @COSTALWAVESWIRES Similar situation here. I listened to short-wave in the late 1960s getting many DX broadcast stations using a long wire antenna in my parents attic. But I didn't get into Ham radio until very recently.

[@LarryBingham1971]

I didn't even need to watch the whole thing and knew this video was needed. Thanks Walt for putting it together. Great primer for LDG products!

[@digitaldreamer5481]

Aloha Walt, I just bought the LDG 4:1 and the LDG 9:1 Unun based on two of your videos. I love random wire and telescopic antennas with my Xiegu G90’s. ❤

[@foreheadlstudios2936]

Just getting back into the HF side of the hobby after some 20 years of inactivity. Originally licensed in 1980. This video is a great example of why this is my favorite ham radio YT channel. Thanks much, Walt, and 73. Tim, W4TAF

[@randalld92]

Thanks Walt. I’m a new ham and finding simplified information isn’t easy. Too many content creators talk over the new guy’s head. I don’t know if they fear that dumbing it down will cost them views by more experienced operators, or if they just assume that we come in with a certain amount of knowledge. Anyway, I truly appreciate your content. Your DXing videos are what pushed me to get my general ticket and buy a G90. Hopefully I will catch up to you on the air sometime. Thanks and 73!

Thank you Walt for giving me a good basic understanding of baluns and ununs. You gave me a good understanding of why they are used and what type of antennas these transformers should be used on. You gave me a great foundation to build on. Other KZbin videos explain the windings and turn ratios, etc. without explaining why and where they are used. You are a great teacher/instructor. Thank you very much.

Love the ol Hammarlund radio. I had an HX145. Probably like yours without the clock. Vintage 1963, just like me.

[@COASTALWAVESWIRES]

That radio has an incredible story. It belonged to a SK that lived in the house across the street from me. He died decades ago and the people that own the house now told me there was an old radio in the attic I could have if I would climb up there and get it. Well, there it is in my shack.

[@MyHamRadioJourney]

Walt, THANKS! As you know, I have been a long-time Ham, but I am new to building antennas. And you were right. This is the video I needed to watch. I have a list of notes to stick in my POTA case to help me in the field. Thanks again for all you do to help this amazing community. 73s.

Many years ago (during my CB days) I learned a balun can be a really neat thing. But you have to be willing to experiment a little. Someone gave me a 4-element beam which had an insulated dipole driven element with a hairpin match (He did not know how to feed it). Not wanting to try and feed it directly with coax (did that with another similar beam one time with poor results), I decided to try and feed it with a 1:1 balun. Since the dipole driver would have a 75-ohm feed point impedance, I connected the balanced side to the hairpin, and used 75-ohm coax to feed it (not CATV coax). All I can say is 'wow'! Not only did the antenna work very well, it was also the quietest antenna I have ever had. The SWR measured at 1.3:1, and I could hear signals others could not, especially in dry-air Santa Ana conditions when the air becomes 'charged' and a lot of static is present. The hairpin match provided an awesome DC ground which, in combination with the balun, provided a virtually noise-free beam. I used it for many years before a wind finally blew it down. Wish I still had it!

Walt, thanks for the info! Today I decided to build a 41' random wire. I was impressed with the fact that my 7300 tuned across all of the bands. Unfortunately for me I didn't have the means to get it up in the air very high so incoming signals were kind of weak. Next spring we'll get it up higher to see how it performs.

We live on the far eastern fringe of the Los Angeles area, in San Bernardino County, and my stereo systems AM/FM receiver struggles to pull in even the mighty KFI 640kz signal with their tower located not that far away. Everything else is just noise. So far, I'm just using the wimpy post-card sized wound wire antenna that came with my receiver, which only excels at bringing in noise from our lights and other electronics. Now I'm no ham operator. I was an avionics tech and airborne radio operator on USCG aircraft in the distant 70's, and I've been a fan of the AM band, static and all, since I was a kid. I recently found a Radio Shack longwire antenna kit amid my garage debris, and thought I might string it up on the roof, going from one chimneys the other and then across the roof a bit more. The twisted copper antenna wire in the kit is about 75-80 feet long. Way short for full wave or even half wave So I'm not TXing here, just RX. Should I go with the full 80 feet or trim it down? To use the full length, I'd have to dog-leg it, up to 90 degrees or so. Would this degrade my reception, or possibly improve off axis reception? I'll be using maybe 20 feet of 50 ohm coax for a lead-in. Would I benefit from a unrun? (Something I never even heard of before). Anyway, any help is greatly appreciated. Great and Informative video.

Those splaining glasses does the work! Easy to understand for new hams!

[@COASTALWAVESWIRES]

Hahaha those splaining glasses work!

[@hennero.3826]

Thank you, Walt. 🙂 I got the basic thought (matching the feed point impedance to the impedance of the coax, and to what the transceiver expects). However, what I do not yet understand is why the 1st random wire antenna in the video has 300..360 Ohms, whereas th 2nd one has 150..250 Ohms and thus they need different UnUns. The table you showed suggests that it has to do with the length of the driven element, as the ones above 8 m require 9:1 as opposed to the 4:1 of the shorter ones. Is that feed impedance something that one can calculate/measure to make the right choice for the UnUn ratio? If so, how? 🤔

[@hennero.3826]

Wait - seems like my question is obsolete: I just found your other videos "Antenna Wire Length - Demystifying Feedpoint Impedance" ... 🙂

[@COASTALWAVESWIRES]

Oh that’s great and thank you for supporting the channel!!! 73, Walt

[@nateitkin8279]

Thanks Walt. That was helpful. I had a couple EE classes in college 40 years ago when I earned my mechanical engineering degree, but there was zero material about RF antenna design. A friend of mine has a MS in EE and even that didn't cover much about RF. It was mostly IC design and signal processing for him. If the terminology was unbalanced match and balanced match versus unun and balun that would go some distance. The next step would be describe the circuit in a balun and the circuit in an unun and explain why it works for each type of antenna, respectively.

[@COASTALWAVESWIRES]

Thanks! I’m not sure if KZbin is ready for a structural design engineer to break down the circuit design of a balun or unun but I guess I could give it a try LOL. All the best and 73, Walt

An antenna tuner is only an antenna tuner when it is at the antenna. Matcher is more like it. Nice video Walt. I got a 9:1 kit from Palomar Engineering years ago and built as there instructions as a unun. Turns out it was an 8:1 not a 9:1 and there reason in the directions was the core selection. years later and a lot more education. It tested as a 8:1 not a 9:1. It will work with a non resonant but it will not tune quite right. Live and learn. I sent them an email over this, we will see what happens. I will rewind it so it is a proper 9:1 and make it useable

[@COASTALWAVESWIRES]

[@COASTALWAVESWIRES]

Thanks for watching! I’m a SWL guy myself.

[@loraz0]

Hey Walt! another great video! I like making my own, rather than buy them. When you describe the impedance in ohms, That is exactly how you test them. I have resistors soldered together that approximate the EFHW, Random wire, or delta loop. Connect them to the antenna connection and the counterpoise connection or to the shield side of the coax. Then connect your swr meter, and if they give a close to 1:1 reading, you know they will do the job. When you make your own, you can tweak the windings, and tune them up even more. Have you seen the Gabil GRA-HF750T antenna setup? You can turn your qrp rigs into an HF walkie talkie with these. Add a short counterpoise and they will amaze you.

[@redstickham6394]

Great video giving an easy to understand explanation. When I got licensed, UnUns weren't really being used but now they seem to be pretty popular. I had a random wire(not sure how long it was) antenna that was fed with single wire that went straight into the tuner. I wonder who many hams still do that? It worked well but on some bands the RF in the shack made the rig go a little haywire if the power was up too high. Your videos are always informative. Keep up the great work.

[@COASTALWAVESWIRES]

Thank you so much! I’ve been thinking about building a long wire antenna with that TenTec antenna coupler I showed in the video. So it would pretty much be like your antenna you described. 73 my friend!

That would be awsome! Thank you@@COASTALWAVESWIRES

[@stirlingpark6145]

An excellent explanation as always Walt. It makes sense to those who don't know. However, there is one basic assumption that most YTers make, they assume that a budding antenna builder knows what the impedances are to start with for a prticular aerial configuration, I recall I think DC showing a dipole fed in the centre = 50 ohms and then moving the feed point to one end until it became an EFLW and the impedance was as high as it was "going to get". Obviously the baluns for this would start at 1:1 going through 4:1, 9:1 and so forth on to 49:1, maybe that is a reference diagram that needs drawing by somebody? Then there could be coverage of those in the 64:1 range or special configurations? Just a thought - 73 de Terry

[@COASTALWAVESWIRES]

Good thought Terry, 73 Walt

[@stirlingpark6145]

Maybe there is a market for a digital power meter that shows SWR and the impedance figure? I know that you can get meters to measure the impedance, but to have it on a straightforward 3 in one meter (that doesn't need a tutorial to remember how to drive it every time) would be a handy bit of kit? @@COASTALWAVESWIRES

Check your Balun/Unun. I bought a cheap 4:1 balun and installed it on a 17-5 antenna. Could not get the antenna to work properly. Narrowed the problem down to the balun. Took the balun apart and realized it was wired just opposite. It was a 1:4 instead of a 4:1. Simple to unsolder and rewired. That fixed the problem. SWR on 20 meters was less than 1.5:1. Probably rare problem but it can occur.
