I have built my own design 2 element beam for many locals here. I have worked dx all over the world with this design. It really works and is dirt cheap to build.
So you're using steel instead of aluminum? Thats interesting. I might have to try that. Here in az we don't have the corrosion problems other parts of the country have. (Its a DRY heat, lol)
I sure enjoy watching your videos. I like all of the tinkering and homemade antennas. I also like seeing the distance tests you and Mrs. Mower junky do. 👍
I built a 4 element yagi , very similar to that 30 plus years ago. The reflector and directors do not need to be isolated from the boom , only the directly driven element, I used a Hy Gain BN 400 beam balun and short jumper to each half of the driven elements, same 2 inch spacing and isolation from the boom

I just got into gmrs radios and I have begun building antennas. Very fun hobby. Working towards my amateur license soon. I just constructed a copper yagi gmrs vhf. Andnit works good I need parts to get my gamma match solid but the antenna works well and has a lot of gain
@thechristianbiker812 in my experience it's a lot based on your local topography. I can get a pretty steady 35 miles to a repeater in my area. days good propagation days I can get around 40 miles. Reaching a repeater that is. Simplex radio to radio I can average around 15 miles max in my area. Def varies based on terrain. I'm in north east Ohio.
@thechristianbiker812 of course it all depends on location. Radio and antenna. A base antenna around 25 to 30 ft does well in a lot of areas with a good antenna or one atkeast tuned for gmrs. Sometimes the 70cm dial band antennas are not quite good enough swr wise and tuning to do good for gmrs freq. I love building and doing. I am a ham operator now and I built my own gmrs repeater here in my hometown so it's been fun and i love the hobby. Gmrs is what got me into radio and i will def. Be continuing it for the matter of family comms. Imo a good quality radio meaning a better name brand thay baofeng will do you wonders. The cheap radios can get u started but. A yaesu or a icom handheld is def worth the money for range and reliability. I have 3 baofengs that no longer work. So sometimes the money pays
Excellent job, CB at its best, just doing it right !!! Another good project. I am supposed to have the makings for a light 3 element beam, maybe you have motivated me to find that box and build it. Nice analyzer you have there, I kinda expected you to get one as much antenna stuff as you are doing.

What I use for element insulation is Stauff Hydraulic pipe mountings on top of aluminium flat bar or plate. It's much more robust. To terminate your coax to the driven element; drill a small hole through the element each side and use a stainless metal thread and nuts and connect the cable with electrical terminals. Use a 1:1 current balun / choke in the coax.
Nice job 151, these antenna project videos are really good. Looks like your cats just wanted to be in the video too. Ice storms can be brutal and agree your antenna held out good.

THANK YOU FOR THIS VIDEO!!!! I PURCHASED A SIRIO SY-4 I NEVER GOT IT TO WORK. THEN WHEN I GOT MY MACO 5/8 AS THE REST OF MY CB NEIGHBORS(N.C.), I SAID THE SIRIO IS JUNK & I GOT ROBBED!!!! NOW, YOU GIVE NEW LIFE TO MY ANTENNA! ALL I HAVE TO DO IS GET 2 HOSE CLAMPS AND A PIECE OF PLEXI GLASS AND A TAPE MEASURE!! THANK YOU. WHAT WOULD I SHORTEN OR ADD LENGTH TO FOR CHANNEL 20 OR 11? IF I MAY ASK.
So, I would guess by mounting the reflector directly to the boom, element spacing and element length may need to be more radically adjusted where as insulated from the boom, the dipole formula and 5% longer reflector may get you closer from the get go???
@@MowerJunkie Let's do it again. We have a nightly round table on 38. Right now I'm using a 125ft wire doublet fed with 600Ω open wire ladder line horizontally stretched out east the west.

I've still got a silver rod on the roof of a 18 story building here in London. Height really is might. I'll be taking it down soon coz it's getting bent and battered up there (they don't make them like they used to) I'll be putting up a 4ft shorter fibre glass antenna. The sigma 2011 skip master 5/8 wave.. the silver rod is still a great cheap antenna which served me very well. I tell you what the silver rod ain't scared of the antron 99. If the antron fancies a knuckle up the silver rod is ready to go. Just say the time and the place and the silver rod will be there 🌚 it just sees the antron as a skinny puny bit of wire. Anyway Queensbury rules🌚?
I like it, really clean construction. I've always had the best luck with .2 wavelength and yours is real close, 86.5" being ideal from what I've seen, but at .225 you may have a bit more gain and a slightly less F-B but I'd take it! You might check out an Omega match - it's much better than a Gamma and is a balanced match! I hope I get to DX with you soon, who do I listen for on 38Lsb? - World Radio # ?
Beautiful, I wonder how much worse is local communication to the car and to another base of vertical antennas? As factory-made, it looks good. The wife is right :) Health for you :-)
Good job mower junkie…. I’ll have to set up so I can can come off channel 6 to go say high up on 38 lsb someday. I’ll prolly build a little 2 element gizmotchi or a 3 nothing like I run for the super bowl..
how does your 2el "yagi" compare to a single element dipole, any gain over the single element dipol ? the footpointresistance will not be 50Ohm, when there is the second element or more elements. what does the SWR do, if you turn up the calibration knob of that SWR-meter to the max, still around 1,2 or does it go to like 2.2 or even higher ?
the SWR meter I used is part of an antenna analyzer, it does not have a calibration knob, it has a frequency adjustment knob. With the antenna 28 feet off the ground it has a resistance of 49 ohms, and 1 to 1 SWR on channel 19.
APPROXIMATE YAGI-UDA ANTENNA GAIN LEVELS NUMBER OF ELEMENTS APPROX ANTICIPATED GAIN DB OVER DIPOLE 2 5 3 7.5 4 8.5 5 9.5 6 10.5 7 11.5 so you can see the best bang for your buck is a 2 or 3 element beam. To go from a 2 element beam as .22 wave length (appx 8') to a 55 foot boom for a 7 element boom (using the same .22 wave length spacing) "ain't worth the hassle or trouble" for only 6 db gain (1 s-unit on the receiving station). MJ didn't mention but the .22 spacing is for maximum forward gain. You can shorten the 8' spacing and improve how broad band the antenna. 73
Man, that antenna looks good ! Do you think I can get it tuned to 27.225 for the European 22 CB channel ? And how ? I need to make it bigger or smaller ?
Nice I like that..was you bare foot when you talked to Canada??. How many watts will it take..? 73s..la 350 central Louisiana.i got me a maco 5/8 wave ground plane now.does great may build one like you.
@@MowerJunkie one last question please I have bad line noise or interface.what do you think about noise eliminators or ferrite any suggestions.thanks any videos you have on that?
Check out this video, ua-cam.com/video/quJzBENg2a8/v-deo.html I had a 2 element Yagi with 2 rotors, so that I could run it anyway I wanted to. Thanks for watching, Take care.
the element is made out of multiple lengths of pipe that slide into each other, so you just loosen a clamp, and make the element longer or shorter to adjust the SWR.
What about using a balun or current choke to decouple the unbalanced coax (52 ohms) from the balanced dipole driven element (75 ohms) which remove the problem of radiation from that coax. Additionally the vswr shown on that meter will not be accurate if the coax is not decoupled from the driven element with a current choke. Then you should transform the 50/75 ohms impedance mismatch for efficient power transfer. Since it is a mono band antenna a gamma match is simple and easy to make and will fix all these problems.
the addition of the reflector lowers the feed point to around 50 ohms! 75 ohms is only when well away from objects! a choke is a good idea but not needed. the 50 vs 75 ohm is not a problem in the old days you would use 75 ohm rg 11 or rg8 intrchangably as you could get 50 or 75 ohm swr tester and the output of radios wear tunable from 25-150 ohms! the loss from a 1.5 to 1 swr is not detctabel in radio land! the old radio books do a good job of explaning swr etc not the new ones! read one from pre 1940 it will explane it at enginring level yet make it clear for lay men!
With each element being 102.25 with a 2 inch spacer, wouldnt that be a total of 206.5 instead of 204.5? Not trying to be nitpicky but I am going to try to build one. Thanks
Yup, lol. I noticed my mistake after I published the video. Yes the total length with spacer is 206.5"

Thanks again for sharing such great video's on buliding antenna's. Every one of them has been very informative.
Looks good! And Wife approved 👌. As long as you can maintain that "domestic tranquility factor"! Lol.

Dang ! You've got yourself some kind of Mojo-Machizmo ! Hey, I a New Subscriber ! WOOT ! WOOT !
Thank You so much, 73's from 151 SC.
Point that masterpiece towards wisconsin! 608 South Central Wisconsin saying 73s to ya!
It's pointed at you now.......But it's dead quiet. I hope to hear you soon 608, 73's from 151 SC.
THANK YOU FOR THIS VIDEO!!!! I PURCHASED A SIRIO SY-4 I NEVER GOT IT TO WORK.
THEN WHEN I GOT MY MACO 5/8 AS THE REST OF MY CB NEIGHBORS(N.C.), I SAID THE SIRIO IS JUNK & I GOT ROBBED!!!! NOW, YOU GIVE NEW LIFE TO MY ANTENNA! ALL I HAVE TO DO IS GET 2 HOSE CLAMPS AND A PIECE OF PLEXI GLASS AND A TAPE MEASURE!!
THANK YOU. WHAT WOULD I SHORTEN OR ADD LENGTH TO FOR CHANNEL 20 OR 11? IF I MAY ASK.
Most wife's would be less than pleased to have that on their house!! 😂👍❤️
I know it.....I'm a lucky man! Take care, 73's from 151 SC.
Most good wives wouldn't care as long as their man is happy. My man mower obviously has a fine lady. 73 from London
So, I would guess by mounting the reflector directly to the boom, element spacing and element length may need to be more radically adjusted where as insulated from the boom, the dipole formula and 5% longer reflector may get you closer from the get go???
Looking good 151! Give me a shout 497 on the South side of Lake Murray.
Thanks Brandon, I talked to you on this antenna, when it was only 10 feet of the ground. Take care 497, Thanks for watching.
@@MowerJunkie Let's do it again. We have a nightly round table on 38. Right now I'm using a 125ft wire doublet fed with 600Ω open wire ladder line horizontally stretched out east the west. I'm working on getting my old full wave box quad back up for 11 meters. It's a all fiberglass antenna with no metal except for the mast plate and the end caps for the spreaders. This is 22 Chuck's old design. No gamma match just only 1/4 wave stub fed with a piece of 75 ohm cable. 73! 497 Brandon
You did good job on this antenna.
If the xyl likes it. You know you did a good job. 🤗
Excellent build 👏.. is it possible to add a heating line, for melting the ice? Just thinking out loud..
Thanks J P. I don't think it needs a heater, I've been here for 8 years and this is the first time We've had an ice storm. Thanks for watching, Take care.
i love this video idk how many times ive watched this...lol maybe 500 times but love it
lol, Thanks Mike.
@@MowerJunkie your always welcome bud..if i could find the aluminum i would follow your video to a tea to build me one..:D
Nice antenna! 921 Maine/Bobcat waving!
Wow Worked well Great Build.
Hey Mr Mower, use Conext Link RT4N-2 Screw Ring Terminals for the feed line. Way better connection.
Mower junkie do you still have the 2 element Yagi hooked up, That really was amazing talking to Canada
I don't have it hooked up at the moment, But I do still have it. Thanks for watching, 73's
Hi Pal nice job on your Antenna! 948 said that!
Thanks 948.
Nice nice from 290 in the great lakes i have 2 pdls. I have one for parts an one is goin up soon
Nice! The PDL-2 is a great antenna. Take care 290, 73's from 151 SC.
probably the best antenna ever made. Small, light weight, with the full wave elements. Quad antennas are bad to the bone.
What was the SWR once you raised it above the house? The higher the better on the flatside. Looks like your sweet spot.
Yup, it went flat on channel 19, and 1.1 on 1 and 40. it ended up having an SWR of 1.5 or less from 26.5 - 27.9 mhz. Thanks for watching, Take care.
IF I MAY ASK............. AT THE FEED POINT , IS THERE ANOTHER WIRE FOR GROUND TO THE MAST?OR DO I RUN A SEPERATE GROUND FROM THE BOTTOM OF THE POLE TO MY LIGHTNING ARRESTOR?
My build was not DC grounded, just the coax connects to the active element.
At times you such a nut, John. But that's what I love about you. I sincerely mean that in a good way...rusty clamps, we won't be that critical. 73 & happy weekend de your badass Friend Uncle Guenter
Thanks Uncle Guenter. 73's from 151 SC.
Just a?, would it have made a difference if the folks were facing down and the plexiglass on top Just wondering?
for the best performance the element should be above the boom.
I don't know much about CB. What does the 158 and 215 indicate? Location I assume. But what term is used to refer ti it??? Thanks for the vid.
Nah. A lot of guys use numbers for their handle. Sometimes the old heads use the last of their license numbers back when CB required one.
You Must have a good heart for Animals, Cause cats pick you, That means they trust and love you, Our 30 pound Tabby is our Child, Back to the Antenna, Do you have a schematic, for this, I,m old and Blind, and have not had a CB in 20 years when I stop Driving Tractor over the road,. , But I had a Big radio then ,So your saying you have 2 separate 102,1/4 on each end, But not connected, Is that right, and other side same length but they are Connect in center. I know this Might be a stupid question, I just don't remember. Thanks for any Help Brian
I've still got a silver rod on the roof of a 18 story building here in London. Height really is might. I'll be taking it down soon coz it's getting bent and battered up there (they don't make them like they used to) I'll be putting up a 4ft shorter fibre glass antenna. The sigma 2011 skip master 5/8 wave.. the silver rod is still a great cheap antenna which served me very well. I tell you what the silver rod ain't scared of the antron 99. If the antron fancies a knuckle up the silver rod is ready to go. Just say the time and the place and the silver rod will be there 🌚 it just sees the antron as a skinny puny bit of wire. Anyway Queensbury rules🌚?
Throw an antron 99 up an talk around the globe
I miss my 99 tried em all im runnin an imax 2000 for last 5yrs works ok
@@Randy-lf2dp the silver rod gives the antron a run for its money all day long. It's quite confident it'll kick the antrons arse🌚
Good luck with Your new antenna, I hope it works great. Thanks for watching, 73's
@@zukispur5493 i hear you but antron low low maintenance i like sirio 827 an the sirio 2016
I like it, really clean construction. I've always had the best luck with .2 wavelength and yours is real close, 86.5" being ideal from what I've seen, but at .225 you may have a bit more gain and a slightly less F-B but I'd take it! You might check out an Omega match - it's much better than a Gamma and is a balanced match! I hope I get to DX with you soon, who do I listen for on 38Lsb?
- World Radio # ?
If I cut down a match system two 30 inches will it work for 2 elements MaCo beam
Great video. Do you have all your measurements posted somewhere that can be downloaded? Thanks Again.
No, sorry, But all the info is in the video.
Sorry for being dumb, but I'm new to this. What side do you point in the direction you want to work, Reflector or Drive?
The driven element gets pointed where you want to talk. the reflector is in the back, and reflects the signal toward the driven element.
Beautiful,
I wonder how much worse is local communication to the car and to another base of vertical antennas?
As factory-made, it looks good. The wife is right :)
Health for you :-)
this antenna is best for Skip, and locals that are on flat side antennas. it does not do well with local verticals.
Good job mower junkie…. I’ll have to set up so I can can come off channel 6 to go say high up on 38 lsb someday. I’ll prolly build a little 2 element gizmotchi or a 3 nothing like I run for the super bowl..
Thanks, I'll be listening for you on 38 (the other Superbowl) Take care, 73's from 151 SC.
Very nice build!
How much would you charge to make a antenna like that and I come pick it up ??? Thanks
how does your 2el "yagi" compare to a single element dipole, any gain over the single element dipol ?
the footpointresistance will not be 50Ohm, when there is the second element or more elements. what does the SWR do, if you turn up the calibration knob of that SWR-meter to the max, still around 1,2 or does it go to like 2.2 or even higher ?
the SWR meter I used is part of an antenna analyzer, it does not have a calibration knob, it has a frequency adjustment knob. With the antenna 28 feet off the ground it has a resistance of 49 ohms, and 1 to 1 SWR on channel 19.
APPROXIMATE YAGI-UDA ANTENNA GAIN LEVELS
NUMBER OF ELEMENTS APPROX ANTICIPATED GAIN
DB OVER DIPOLE
2 5
3 7.5
4 8.5
5 9.5
6 10.5
7 11.5
so you can see the best bang for your buck is a 2 or 3 element beam. To go from a 2 element beam as .22 wave length (appx 8') to a 55 foot boom for a 7 element boom (using the same .22 wave length spacing) "ain't worth the hassle or trouble" for only 6 db gain (1 s-unit on the receiving station). MJ didn't mention but the .22 spacing is for maximum forward gain. You can shorten the 8' spacing and improve how broad band the antenna. 73
I hope to be able to build some antennas this spring and summer
Love your videos! I am going to build a two element using your dimensions. I just do not understand the connection to the driven element
the 2 half's are separate, and the coax gets connected directly to each half. center conductor to one, and shield to the other.
Thank you very much. I am going to start building one tomorrow
Nice antenna build are you going to gear it up again to go vertical
I think I'm going to keep this antenna for flat side only. Thanks for watching, 73's from 151 SC.
Man, that antenna looks good ! Do you think I can get it tuned to 27.225 for the European 22 CB channel ? And how ? I need to make it bigger or smaller ?
Thanks, it would need to be about .5" longer, to have a good tune on 27.225 Thanks for watching.
Thank you. 73
Is the plexiglass UV rated because if it not it will fade turn milky white and become very brittle!
it is UV rated, but I still put 3 coats of paint on it. Thanks for watching, Take care.
Nice I like that..was you bare foot when you talked to Canada??. How many watts will it take..? 73s..la 350 central Louisiana.i got me a maco 5/8 wave ground plane now.does great may build one like you.
I was running about 150 watts when I made the contact to Canada. Thanks for watching, 73's from 151 SC.
@@MowerJunkie one last question please I have bad line noise or interface.what do you think about noise eliminators or ferrite any suggestions.thanks any videos you have on that?
That plexiglass looks a lot like the back plane of a flat HP monitor
Good eye, it did come from an old monitor. some of the older flat panels have a 1/2" thick piece in them. Thanks for watching, Take care.
Great job!
Great antenna 👍 can a ask where you got your build dimensions from?
I used an online Yagi calculator, that I found with Google's help. Take care, Thanks for watching.
I trust anyone that cats trust.
Have you ever tryed to set it up vertial it may work let me know if you ever try.One person I did know made it out of copper pipe.
Check out this video, ua-cam.com/video/quJzBENg2a8/v-deo.html I had a 2 element Yagi with 2 rotors, so that I could run it anyway I wanted to. Thanks for watching, Take care.
nice work plan on building one
Another good Antenna Video from you Mower Junkie
Thank You so much, 73's from 151 SC.
I think easyies make one theses get one of those pool pipes for light weight.
Is that a Aluminum boom? What does it weigh all together? Thanks..Bossman 767 Southern Illinois
Yup, it's all aluminum, But I have no idea what it weighs. Take care 767, 73's from, 151 SC.
How would you adjust the SWR on something like that if it was too high I didn't see where you can adjust it
the element is made out of multiple lengths of pipe that slide into each other, so you just loosen a clamp, and make the element longer or shorter to adjust the SWR.
@@MowerJunkie thank you so much
What about using a balun or current choke to decouple the unbalanced coax (52 ohms) from the balanced dipole driven element (75 ohms) which remove the problem of radiation from that coax. Additionally the vswr shown on that meter will not be accurate if the coax is not decoupled from the driven element with a current choke. Then you should transform the 50/75 ohms impedance mismatch for efficient power transfer. Since it is a mono band antenna a gamma match is simple and easy to make and will fix all these problems.
Builder told that his antenna at feedpoint is 50 Ohms, so no impedance mismatch. I agree about a current balun though. de YL3GU
the addition of the reflector lowers the feed point to around 50 ohms! 75 ohms is only when well away from objects! a choke is a good idea but not needed. the 50 vs 75 ohm is not a problem in the old days you would use 75 ohm rg 11 or rg8 intrchangably as you could get 50 or 75 ohm swr tester and the output of radios wear tunable from 25-150 ohms! the loss from a 1.5 to 1 swr is not detctabel in radio land! the old radio books do a good job of explaning swr etc not the new ones! read one from pre 1940 it will explane it at enginring level yet make it clear for lay men!
does the reflector have to be insulated from the boom like the driven mount??
the reflector does not need to be isolated, it can be attached directly to the boom.
What would happen if the elements were vertical ?
it would be vertically polarized.
Hi love the video how high is the mast 73s from 416 Trinidad
The boom is about 28 feet up. Take care 416, 73's from 151 SC.
