Thank you Dave for this in depth series on Balun's. A 1:1 balun has always been something I thought as an important part of a dipole antenna system. These videos give the average amateur, like myself, the confidence to pursue the projects that are covered in the ARRL publications. Paul VE3SQM Toronto, Canada
Dave, What a wonderful, thoughtful, how too video. First licensed in1960. I Balun thought about "Home brew" Thank you for your time and showing how too build stuff. 73Jerry - KK6YO
Hi Dave, great video series. I greatly appreciated the detail handy work, start to finish you show,. Simple tricks, a lot of times missing from other videos to save recording time. I grabbed many of your techniques that I'll use. I agree with an previous reply that you give the average amateur a "how to DIY" confidence for homebrew projects. Thank you ---Bob
Thank you so much for the effort to bring this to everyone. I will be setting up a station in the Philippines. So much I this will have to be DIY, You are a huge help. Thanks.
I followed this Build to its end; and I am at a loss why you went thru the trouble to 'notch' out tht 6" pipe on the connector side. There were no interference items in that end. Since I had done them, I added Eye Bolts to the connector end as well to tie cable strain reliefs to. Thanks for the awesome Project.
Thanks a lot for this! Going to build my first 20m dipole soon, and wanted a neater solution than the "ugly balun" most people seem to go for. This is about as neat as you can get, says my limited experience. 73s de SA5FTP
Was thinking instead of routing the wire from the case to the outside, why not use two studs and a wing nut or terminal connector? Then, when wiring the antenna, simply connect the wire to the external stud with the nut?
Great video!! Going to start putting your 1:1 Balun together. Instead of bending wires on outside for connection, could they possibly be fed through the center and connected? Thank for all of your videos. You give me confidence in completed project will work.
Nice instructions Dave. Would this also work with an SO239 at both ends? I already have an open feeder coming from my 1/2 sized wire dipole terminated in a PL259 so could join it there or would I need to remove the ribbon feeder wire?
NOw I wanted to see you hook up the wire to the Dipole and set the SWRs with the analyzer and watch you adjust the lengths of wire and put it into operation on the band and see how many contacts it will actually make. So when is the rest of the video going to be made, Dave, Mr. KG0ZZ?
Hi Dave, question, when you folded the leads back over the coil, is there a possibility for a short? Could you use some insulating material between the folded leads and the coil? Thanks, I hope to create my own soon.
Hello Mr Dave I am beginner I need to know how to complete this antenna and what kind of wire should put and the mm of wire and the distance by m and witch band I can cover
do you make any ferrite center balun? (todoid or bar) what's the diference between ferrite or air balun in 80 meters performance? Your videos are awsome !!! you make all so simple !! Eduardo LW6EEA 73
Hi Dave, and thank you for your knowledge. Great videos. When using the so239 on the bottom, could it be done for the top as well? Not sure which wire to use on the center lead for the top. I'm gonna ohm it out to see which one to use. I can see this on a beam antenna, but not an omni directional antenna. I am planning on trying it on my 10 to 12 meter rig. Thanks again.
Hello, i own a Cobra 146GTL, can i use this balun for 27Mhz band? The use of this is to balance the resistance of the RG58 cable (50OHM) to the resistance of the dipole (75OHM) ? Is it possible to have a schematic diagram of the coil?
Why kept black wires out of the pvc pipe.it can be adjusted inside with the cap side screws and bolts you fitted on both side of cap.bolts are there inside the cap.you could have fitted the end of black wires inside the cap.
I do have a question I am going to build me a fan type dipole can I use a 1:1 balun on a build or will it mess it up im going to try to copy the alpha delta dx-cc
Thank you for this Dave. Building my first balun today and this is pretty much the best video I have seen on the subject. One problem for me is I can't find those darned flat top caps anywhere! I had to use the rounded ones Thank you! Ian AG5LE
carefully put a dab of crazy glue on the nut and screw it on the pl259 bulkhead connector., let dry, then remove the screw leaving the nut glued on the flange / bulkhead. It will make all the assembly much easier...
Should have put your 259 tightening shield onto the 239 plug before tightening it so the plug would be centered in the hole before tightening the screws or the plug might be off centered and unable to tighten the 259 plug onto the 239 all the way tight due to being off centered, thus allowing water to infiltrate your Balun. Just a thought maybe you will luck out and not have to loosen the cap and re-center the 239 plug in the opening.
Hello Mr. Ted greet me taste , excellent first input for those who like to experiment, my question Mr. Ted sheathed cable can be used for the balun 1: 1 and only exchange the largest and smallest caliber 1.6 or 1.0 kernel mm measurement core is 35 mm in diameter x 80 mm sheathed cable in the roe or would affect the bandwidth, Mr Ted , thanks for your time and best regards 73
Hi Dave! Thanks for the amazing videos and look forward to seeing more in the future. Can I use typical 14 AWG insulated house-wire for this project, or is the magic in the magnet wire?
I ran it with that wire, soldered everything up. 10 guage solid wire out to 30 foot copper and aluminum wire, 16 guage.. It works better than ANYTHING I've tried. Good vid...
He Dave, nice video! Can i get an oppinion on a balun vs ferrite beads? Ive red both keep RF feed out of the coax part (depents on the placing, but still). Are there any pros or cons over ferrite beads? If anybody else reads this, feel free to add your comments to the questions. All help is appreciated. Thanks! Jeff
I like ferrite beads, very simple, and no coils. The idea is to resist rf from radiating back down the coax so the antenna is least resistance, so the antenna trimming is important for a good match. If I use a balun, it is more for a transformer such as 4:1 or 6:1. I also like full wave loop antennas, so baluns are not needed. I try to avoid using matching tuners and baluns, but sometimes it is necessary do to antenna limitations. He did a nice job, and this is a kewl balun too. He was right about a balun being better than just coax direct to a dipole. I use a 4:1 balun on my 80m inverted v that is not center fed, I had to experiment with the feed point, but it's more broadband than the 1:1 center fed dipole was.
It's like doing a hand stand while taking a shit trying to get those wires through the pvc from the inside, but I eventually got it. hahaha. - Great videos though. New to the hobby and your videos are very informative, and the builds, for being a DIY/home project look pretty professionally done. Will continue watching!
that was a good series but what I took away from that was for 30 bucks I think ill just buy mine I may build one for fun but any more than that I think ill just buy them
I love step-by-step videos from knowledgeable people. It makes it a fun project. Thanks.
Dave, thank you for this series of videos. The fan dipole I built using this balun had served me for over a year and is still going strong.

Thank you. I have spent the afternoon looking for videos on home brew baluns. Now it is time to hit the back button and like each video. 73s.

really enjoyed that video Dave cheers . Pete in CA
A heaviness of videos! Una pesadez de videos !
It was a really good work, Dave. Confratulations from Brasil (São Paulo state).
Thanks Dave ,great info ,wishing well and greetings from Ukraine!!
Dave, great workmanship as usual - VK8FLLA.
Was thinking instead of routing the wire from the case to the outside, why not use two studs and a wing nut or terminal connector? Then, when wiring the antenna, simply connect the wire to the external stud with the nut?
Can you explain how does the input and output share the middle coil without having to cancel each other?
Hi Dave i just finished making the Balun . came out great thanks . Q what is the coverage of it is it 0 to 30 ?
Great video!! Going to start putting your 1:1 Balun together. Instead of bending wires on outside for connection, could they possibly be fed through the center and connected? Thank for all of your videos. You give me confidence in completed project will work.

Dave, congratulations to the videos! I would like to know how you measure how many ohm has the wire dipole antenna to calculate the balun.

NOw I wanted to see you hook up the wire to the Dipole and set the SWRs with the analyzer and watch you adjust the lengths of wire and put it into operation on the band and see how many contacts it will actually make. So when is the rest of the video going to be made, Dave, Mr. KG0ZZ?
Hi Dave, question, when you folded the leads back over the coil, is there a possibility for a short? Could you use some insulating material between the folded leads and the coil? Thanks, I hope to create my own soon.
Think I will just buy one. It was great to see how they are made though.
Hi dave is this balun suitable for operation in 6 meters?
Sorry no. It's for 1.8 to 30 MHz and it should handle full legal limit.
Great tutorial Dave.. What is the power handling rating of this balun?
So how many uH does this work out to ?
Hello Mr Dave I am beginner I need to know how to complete this antenna and what kind of wire should put and the mm of wire and the distance by m and witch band I can cover
Very good job.
Is there a way to test your work before you glue everything together?
Amen to that. Dave, could you add part 6 to show testing for common mode rejection and SWR plots for 1:1 test over the operating range?
do you make any ferrite center balun? (todoid or bar) what's the diference between ferrite or air balun in 80 meters performance?
Your videos are awsome !!! you make all so simple !!

I understood everything until the end about attaching the antenna lines to the Balun YOU built
Just did mine
Looks nice.

Hey could I make a smaller version for 5 Watts of VHF? Namely a balun for my aircraft radio in my plane. Say 1/2 inch PVC, 10 turns of 18 gauge.
I don’t see the value in an airplane on VHF.
@@mbrownz71 Ummm that's how planes communicate with other planes and controllers.
Nice video Dave, Do you sell any of you stuff?
i need to design a1:1 balun for my 1Ghz dipole antenna. how do i do the calculations for the balun?
Hello Mr. Ted greet me taste , excellent first input for those who like to experiment, my question Mr. Ted sheathed cable can be used for the balun 1: 1 and only exchange the largest and smallest caliber 1.6 or 1.0 kernel mm measurement core is 35 mm in diameter x 80 mm sheathed cable in the roe or would affect the bandwidth, Mr Ted , thanks for your time and best regards 73
But which one is the center lead?
Hi Dave! Thanks for the amazing videos and look forward to seeing more in the future. Can I use typical 14 AWG insulated house-wire for this project, or is the magic in the magnet wire?
Can i use 16 guage speaker wire with the cjear coating, instead of wire you used?
I ran it with that wire, soldered everything up. 10 guage solid wire out to 30 foot copper and aluminum wire, 16 guage.. It works better than ANYTHING I've tried. Good vid...
That looks like an all day project. I can't wait to get started! 73s Fred N3KMA
eu sentir falta do ferrite, por que não usou ferrite?????
It will only work on one or two bands on upper HF with an air core...Need a ferrite core to cover the entire HF region.
I would have tapped the hole in the SO 239 to make mounting a bit easier. But overall, great instruction
thanks dave
Dave good videos. I wanted to ask you a question about antennas can you contact me if its not allot of trouble.
Dave, Nice videos you've been producing! I've been a home brew type of ham and really enjoy your projects.

The power of such baloum would be more then 1 kw due the #14 wire used.
that was a good series but what I took away from that was for 30 bucks I think ill just buy mine I may build one for fun but any more than that I think ill just buy them
Mr. Dave sorry I'm wrong in his apology name,
Where is the math?
up your ass!
