Home Brew 20m Monoband Yagi - Complete Build - How To

[@garycapson6713]

When I was setting my 5 element 6 meter yagi up, I was told to do the same as you did. The swr moved a few kc,s but was great to use.

[@DXCommanderHQ]

Yes.. I have noticed mine moved down a little bit. Perfect.

[@migalito1955]

Ok, 15 years ago I built plenty of Yagi antennas. One technique was to string para-chord between PVC pipe and attach my wire elements to the para-chord. I'd get very compact antennas meaning short boom length by using folded dipoles for the driven element. The folded dipole drove what would have been nearly a 12.5 ohm feed point up to nearly 50 ohms. I don't remember the specifics anymore, but one that I had was a 4 or 5 element 10 meter Yagi built as indicated that had only roughly 5 feet of boom length. I'd often hang these type antennas in a vertical configuration, but they could be stretched out horizontal too. In vertical config you could rotate them, not in horizontal config. One of my most fun projects was an 11 meter 5 element Yagi as described that we used to get bearings on CB'rs . I had also built a loop antenna that was attached to the rear of my jeep. It had a wonderful null especially due to the jeep body being so close. Once we had the bearing the loop would take us to the CB site over time. It was a giant fox hunt played over 15 to 30 miles and was rather exciting to play. Actually it was a hoot to locate CB stations. It felt a bit like the WW2 days of hunting down spy radios.

[@DXCommanderHQ]

Haha.. Great memories!

[@forgediron]

Hi Callum, Use a bit of cloth on a string then suck it theough the tubing with a vacuume cleaner. Then use the string to pull your wires through inside of the tubing.

[@DXCommanderHQ]

Or borrow John's Cobra LOL!

[@jackK5FIT]

That thing is huge! Can't wait to see it go up on the tower. I use liquid tape on projects too and it will wear off. I had never heard of checking the tune on a yagi by standing it up but looks like it works. I will continue to follow the projects because they're fun to watch. Thanks!!

[@DXCommanderHQ]

I love it!

[@KC4LZN]

Ahhh, the joys of experimentation in the world of ham radio! Keep up the good work, Callum.

[@DXCommanderHQ]

Thanks, will do!

[@ianbardell8030]

I designed and built a 7 element cross yagi for satellite use. The elements were spaced a 1/4 wavelength apart. They were phased using 1/4 WL 75ohm coax. F/B is about 23dBd gain is 16dBd

[@DXCommanderHQ]

Nice

[@KC1RWR-VE9FR]

I just tested a Force 12 c3 that exact same way - aft to the ground, fore propped up with a wooden pole in the air. Works great for sweeping with an analyzer or VNA!

[@DonDegidio]

Hi Cal, When I was checking the SWR for my Comet CA-52HB4 4 element 6m yagi, I tested it vertical on the ground and again mounted on the tower and found an increase in the SWR from 1.4:1 on the ground to 1.6:1 on the tower. Both were acceptable. Another problem I had 45 years ago when mounting my 24 foot boom tri-band yagi on the tower was that the mounting plate for the mast was 12 feet off the ground. I was much younger then and did get it mounted with some effort. Five years ago I did a complete rebuild of the crank up tilt over tower and the yagi. I had heard of a tilt plate by NN4ZZ that would allow the yagi to remain horizontal while cranking up the tower to a vertical position. I copied his design and made my own tilt plate. Worked like a charm since I could now mount the yagi on the mast at ground level. Doubt you will have the same problem since your boom is 9 feet long and will only be about 5 feet off the ground when mounting your 20m yagi to the mast. You and the family stay safe. PS Sorry I missed you on DX Engineering today. My low back pain was at an elevated level earlier.

[@DXCommanderHQ]

Yes, I've seen tilt plates. Very cool. PS - Good luck with the back.

[@K1NF]

Cal, a Cushcraft technician told me to test the 3 El beam by standing it up on the reflector on the ground when I told him I was testing at 1 meter horizontal on saw horses.

[@DXCommanderHQ]

Saw Horses! FUNNY!

[@DL1GKC]

So cool to see how you master the little technical problems. 💪 I enjoy your videos. Looking forward to seeing the Yagi in action and watch a comparison to your vertical.

[@DXCommanderHQ]

Working on it!

[@djsly25]

Loving the project! Great work Callum!

[@DXCommanderHQ]

Glad to hear it!

[@TheREALJosephTurner]

I can't get enough of watching you built antennas out in the antenna field. It's soul-soothing.

[@DXCommanderHQ]

Oh nice!

[@garryhammond3117]

Great video Callum. Always good to see you go through your thought process and "engineer" it to happen - Thanks. - Cheers!

[@DXCommanderHQ]

Thanks 👍

[@thomasperina2990]

Hello Lord Callum & Fellow radiohaulics: Thank you for this antenna video sir. I truly admire your design + your follow thru your your implementation of your vision . Looking forward to another One of your antenna.

[@DXCommanderHQ]

Many thanks!

[@VA3HDL]

When I did my Yagi I placed on a pole a couple meters above ground like you did, but not touching the ground. The reflector on the ground side and the driven elements facing the sky. Then I adjusted to the desired frequency. Once the Yagi is up in the tower the frequency of the lower SWR can go up some KHz. In my case it when up 40 KHz. Keep all these things in mind. 73 and good luck with your project.

[@DXCommanderHQ]

Copied!

[@Krispin291]

I wish I was back in country so I can do some crazy stuff! Good job sir! Can’t wait for the next one!

[@DXCommanderHQ]

Hang on!!

[@jonny-dn]

Fascinating stuff Callum. Not easy when you haven't got a dedicated videographer!

[@DXCommanderHQ]

It would be a really interesting experiment to have a cmareman (person?) *and* an editor.. And someone to do the thumbnails, manage the memory cards, battery life, lighting, scripts, video ideas, backups, catalogue the clips, fly the drone etc..! LOL

[@jonny-dn]

@@DXCommanderHQ Haha, yes, a very expensive experiment!

[@Skullfocher]

As someone who builds home brew yagis, I would love to see a fiberglass kit like this. I tried a similar thing with a pair of fishing poles as a rotatable dipole for 15 meters. Also had to laugh when you put all the saddle clamps facing the same side of the plate. I knew before you said, something wasn't going to jive. 😅 Well done though. I love watching your builds. 73, K7AXA

[@alanslade2319]

Wow that's amazing, and just standing it up, l would have thought something just would be off. There you go. Learning something new every day, thanks again for the great work Callum , and see you soon. Alan 💯👍

[@DXCommanderHQ]

Why was I thinking this was going to be all alloy… I should have known you would have used your own poles and nicely done too. Looking forward to the on air results.

[@DXCommanderHQ]

Tnx!

[@sparkyboots]

That'd be brilliant if you sold a kit! I really enjoy watching you build new antennas!

[@DXCommanderHQ]

That's the plan!

[@MrEmozer]

Hey Callun. I think you should put some distance between your choke and the conductive boom. I’m pretty sure the way it is shown it will skew its resonant point. If sufficiently skewed it will not choke anything at your frequency of interest.

[@DXCommanderHQ]

Nah.. It'll be fine :)

[@srinivasnyayapathi9083]

@Callum, I am seening this series of video 3 time already, very inspiring. This video is my 6 time just to het the dimensions.

[@DXCommanderHQ]

Yeah.. This is good fun.. I'll do a wrap up video after I've fitted the new pulleys and Dyneema rope.

[@MowerJunkie]

Great build! Thanks for sharing it with us.

[@DXCommanderHQ]

No problem 👍

[@tobyticehurst]

i'm only 6 mins into the vid but already looking awesome Cal, I like those fiberglass inserts! I'm working on footage of the Moxon build I emailed you about using those same 7m poles, they work great for projects like this. Unfortunately on my allocated /p radio nights, the weather has been pants but ill get a YT link sent over as soon as its done. Don't make too much of a mess throwing your comm's about with that weapon.

[@DXCommanderHQ]

Ah! Copied!

[@stewartbaker2752]

To get a more accurate VSWR measurement of a beam at ground level, point it skywards with the reflector at the bottom...

[@DXCommanderHQ]

Now I'm pretty sure that's what I did.

[@Andy-hk4wn]

Thanks for yr video, are there any cheap ways of covering plastic elements with a thin conductive material, instead of wiring?

[@DXCommanderHQ]

8th word in. No.

[@cyrilwoolf8848]

Call just watch your build maybe I will put a cable Thai on each and just in case the tape gives way good build hope you have lots of success with it how to have lots of success with it

[@ronaldblair591]

I remember my dad do that to tune his yagi in the early 70's

[@paulsharp5473]

Well done great build. Why not put the wires in the pole?

[@DXCommanderHQ]

Too close together.. (PS And an engineering nightmare! - I tried it!)

[@andylinton2798]

I haven't watched to the end yet, but ɑ little suggestion is to use copper or steel tape for the elements (ɑ few cheapo tape measures!). Thicker elements = greater bandwidth. But I love the idea of using the DXC poles for the element supports! Next you'll be building ɑ SteppIR!

[@DXCommanderHQ]

Thicker elements might make more bandwidth but a) you would need to make them substantially larger and b) I already get all the band I need :) (c - tape can snap as the element flexes)

[@robertmeyer4744]

Great work. That short piece of RG 58 should be fine. just limits power to about 500 watts . Just watch SWR on QRO. it will start to jump when coax heats up. The SWR should drop even further when on tower. That air choke should be fine. Just 1 band . You could use that VNA to measure the choke . Have to make a test jig to swap shield and center to measure attenuation. I made coax choke out of 6 MM coax. (RG 8X ) 65MM 17 turns worked great at 11 meters. The outher way to choke it is use like 7 snap ferrites type 31 on coax. Ur use a 1:1 Balun . Easy wint on FT 240-31 core with MAG wire . It is a Choke - Balun you made. Balanced antenna to coax that is balanced . It is how it is used what determines what you call it ,If you go buy ARRL antenna book. It just works ! The RF does not come back down the outside of shield. Cheers from NY !

[@DXCommanderHQ]

With low SWR, RG58 will handle high power with ease.. I fully intend to blast it with 1,500W.

[@robertmeyer4744]

I looked up mil spec RG 58/U I have made in UK . at 20 meters CW power is 580 watts cont . With that short piece you should be ok. Just watch reflect on ACOM . If you melt it ,Give it to Mike. LOL I ran 500 watt CW threw what I have and only got warm. and that on 10 meters !

I want one Callum!! You know me and antennas lol!

[@DXCommanderHQ]

HAHA

[@KK6USYHamRadioAdventures]

I have used that method for check the swr on a yagi , it's pretty close. I built a 2 element 20m Yagi out of aluminum a few years ago . The only difference is I made it a driven and a driver, A couple hams encouraged me to do this and it worked great. Your setup would be nice to take portable with a push up pole. Thanks for the video Callum 73.

[@StianEklund]

Looking good, what a fun project!

[@HS0ZIQ]

Can also make a moxon, find they work better than 2 Element yagi, and you get a smaller footprint.

[@DXCommanderHQ]

They don't work "better" it's just they are more compact.

[@KD6HOF]

Exciting! Look forward to hearing you on the air..

[@DXCommanderHQ]

This weekend..!

[@ianxfs]

Great to watch 👍🏻 No droop 👍🏻 I too have a pocket full of scraps of tape….😁

[@DXCommanderHQ]

Haha Ian.. Yeah, I hate dropping stuff on the ground.. I do keep finding odd bits though days later!

[@grandpaandlucas7054]

is the yagi reflector and driven elements or driven and director elements. i prefer driven and director, shorter boom. sure mine on the my 4 element yagi dropped to 28ohms. 5 turns of copper wire wrapped on an inch former and fitted across the dipole center. brought it back to 50 ohms. i made a telescopic boom which i can alter size for the band i want and fit or remove the correct elements for bands all on quick fit connecters. 2 elements on 40mtrs 4 elements on 20mtrs 4 elements 0n 15mts. and 6 elements on 10mts. no tower i use a jcb telehandler to get it 80ft and a tilt plate to keep the antenna parallel to the ground. i have the gear and i have the knowledge but don't have any motivation to play radio. have fun with the yagi.

[@DXCommanderHQ]

OK, this is a reflector. Either makes almost no difference at all. The reason for my longer boom was to get closer to 50 ohms. SHorter boom will drop the impedance. When I move to 3-elements I *WILL* need to match it then! All copied on the rest. Good luck.

[@M7BVV-Phil]

Two words, Cal. Excellent video!

[@DXCommanderHQ]

Thank you kindly!

[@jamiecoburn1231]

Point of curiosity. Will the field of the aluminum "tower" bother with the field or the effectiveness of the the choke? I guess if the SWR is good it just doesn't matter. At some point in a build you have to just start stuffing bits together, sort out the issues as you go, and curse and swear until it works right! :) Sometimes the struggle bus is the only bus! Fun to watch Callum! !

[@DXCommanderHQ]

Indeed.. AT some point, we have to start (as you call it) "stuffing" and see what happens! Brilliant comment.

Hey Cal, curious to know are you using a wireless wifi camera for view of your field with a solar panel? If so what model is it? I see you can view it on your PC which is something I'm looking at doing.

[@DXCommanderHQ]

I use regular cheap Reolink camera via PoE. WIreless would work too since we have an access point in the field. But I would still need wire for the 12V.. So we ran ethernet out to the field when we installed the cables.

Hi Cal any info on the joiners you used inside the rapide poles, what is it size material ect, thanks,

[@chuckrann6282]

Would it improve the SWR curve to use 3 wires on the pole? Each connected but at 120 degrees on the pole.

[@DXCommanderHQ]

Not the SWR.. You MIGHT see very slightly better bandwidth but in all honestly, we're talking only a smidge. Good idea though!

Perhaps ultimately put the DX50 elements inside the poles? If you will be running 1kW it should not affect performance that much.....

[@M0IDW]

Could the boom section be telescopic as well ? Maybe some of the thicker Nebula tubes or would they not be strong enough?

[@DD5LP]

For a horizontal beam what angle to the horizon should we be aiming to get the most radiation close to when modelling? 15° 18° 20°? Is the lower the angle always better?

[@DXCommanderHQ]

OK.. Depends on the day and the distance.. The reason the HUGE contest stations have stacked yagis with "stack-match" switches is to select anywhere from 1-degree (top only yagi) through 3, 5 and 8 degrees (bottom yagi). This is because at super high heights, the lobes can have nulls / consequences. A very high yagi might have a major null at say 5 degrees and you need to dial that out with another yago lower down the tower.. It's a big question and a huge answer (sorry) but most of the time, your DX will be between 3 and 8 degrees - sometimes as high as 15 degrees (under 1,000km).

[@DD5LP]

@DXCommanderHQ hi Callum, thanks for the explanation. I guess the lower the angle the longer the skip distance and so, as you say, the ability to adjust this by switching in and out beams in a stack would be very effective. I'm playing around with a portable wire beam and there I'm looking at 13° at the horizon at best due in part to height limitations. 73 Ed

[@BEDBUGSEPPY]

K3HQX here, Have you ever had the nuts losen up on you due to sympathetic vibration from wind and changes in temperature?

[@DXCommanderHQ]

Actually no..!

[@BEDBUGSEPPY]

@DXCommanderHQ hmm ok. I was concerned for your father as he erected the mast. He was breathing very heavily and he was obviously out of shape. It was not wise in any instance to be putting that up alone. He expressed concern over something going wrong. He should have had another person on the other side to monitor the tension on the opposing guy line. Personally, I would have put up a tower. ROHN 25G would have been fine for 45 feet. That's a lot of torque stress on that rotor at the base. But it was very entertaining. Your father is a smart man! I wish you safe DX ing going forward and please have another person present if you put more antennas up. God bless and 73's

[@DXCommanderHQ]

The breathing is actually the Compressor on the audio mixer. If you dump the compressor, the breathing stops. It's still real but because it's so quiet, the compressor ramps it up.

[@DavidVanDensen]

How did you set up the reflector wire??

Interesting home brew build to be honest. Now I wanna give it a try. I definitely think you should make this as DX Commander Yagi kit. However you might wanna experiment some more. There is a video on this same type of Yagi a guy did but he shortend the elements by using loading coils on both elements both sides and he got the SWR to 1.0. Video here: kzbin.info/www/bejne/bX_CaIeXgc53b9Usi=vfvqkSUs79iA9FPA . Also using 4 DX commander mast is gonna make this kit expensive, but Im sure that can be worked out somehow. Cheers!
