4 Element Yagi Beam DIY
Переглядів 44 тис.3 роки тому
Unit 63, Operator Paul of Columbia SC shares how he made his home brewed Direct Feed 4 Element 1/2 beam for less than $200. After testing it in the driveway on a 5 ft. mast he had so many requests for the specs he decided to share this video. Feel free to email him to get all the details from element size to hardware. Email: unit63SC@gmail.com
Happy new year to you paul and the family . I've Enjoyed talking to you on the band this year. Looking forward to next year chats. Best 73s. WR456🇬🇧.
GOOD JOB BUT you aren't quite finished yet. You have direct coax to driven element connection. That means you have an unbalanced feed going to a balanced dipole driven element. It will work but the swr readings will not be correct because of stray rf floating on the braid of the coax. You say it is 1.4:1 and I am guessing you can't get it lower. That is because the swr meter is not reading correctly. You need a balanced to unbalanced connection using a balun. It will prevent wavy lines on the TV and Computer Monitor. A balun is easy to make or cheap to buy. Cheers VK5LB
Nice job. I hear the calls for you and every now and then I can hear you but I can't seem to get to you. Hopefully we can change that soon. ✌✌

I have being running drive feed antennas for more than 20 years now, I think you need a ground from the ground side of the element to the boom of the antenna to have it working properly. #7 Jamaica Click Click bom bom.
Ahahahaha oh really dude, It's not neat or nice, It's so poorly construct, so where is the gamma match ??. It's all twisted up and down, Honestly I make far better home made antennas down here in Jamaica west Indies with the little tools I have, Damm, !!
Well it's been up 3 years and boasts a 1.3 VSWR on 11 meters, has excellent rejection on the sides and rear and I've talked all over the world. Not to mention 3/4" dia, 1/8" wall thickness elements, single section ASTM aircraft tube Aluminum. This thing is a rock. I know you're jealous but you'll get over it! 😭😭
Hi Paul how's you I think stateside falling out hopefully hear you soon 73s 108AT134 with the big wave 😊
Hey Graeme hope all is well!
@@unit63sc17 Cheers Paul propagation changing had some sporadic e the last few days short skip into Europe 73s take care
Ok I'll be listening for you brother. 73's
Unit 63, how did you come up with the spacing and lengths of the elements? If antenna modeling software, which do you recommend? Thx
I got this design from an operator in FL.
Really cool build How much of a difference donyou notice compared to what you used to use?
I was running a vertical A99. There is no comparison. If I'm giving another station 7dB on A99 I'm giving the 10-20 dB on the 4 element. The receive is 50-75% better also. And most of the time much higher signal to noise ratio.
@unit63sc17 so awesome. I'm gonna use wire but I intend on making one
Nice job
Paul, Thank You for the quick reply to my email, Very Much Appreciated !!! 672 SW Kansas
Unit 63, I got the measurements you listed in this video, bur what is the distance between the elements on the boom if you dont mind me asking ??? 672 SW Kansas 38 LSB I sent you a EMail also
Great question. I included everything in a PDF. Send me an email at unit63SC@gmail.com and I'll send it to you.
Looking awesome 😎
Hey 772 looking at YOU my brother. Mr. Motor Mouth Paul I'm gonna copy this now thank you. QUACK QUACK!!
just finished my own 11 element vertical yagi works great very narrow beam
Best 😊 73 51 from Palle 47AT124 in north Denmark
Open feed with a eye connector..might work for a while at qrp ..but do not try to but power threw that feed....
Putting a KW through it no problem.
Wow I'd be afraid of it breaking down ..well that's great !!! I would.asume u weatherd it ...wow that's great ...I love the antenna ...
It's been up there for a couple years now. Still broadcasting like a big dog!
Awesome video. The grounding part of the video is good info. Thx man !
Some of this is okay as far as educational steps go, but my advice to everyone is to skip ahead and just build an LFA. I'd go with a 4 element, it will blow any of these, and most other antennas, out of the water.
How do you go by lowering the X= the R= 50
A resonant antenna has no reactance, and then there's mutual conductance. Also, there's a common misconception about what the capacitive side of a gamma actually does, this predominantly coming from hams (I'm a CBer). Do yourself a favour and look up how a gamma really works (not on UA-cam!), it's rather interesting, and clever.
@arconeagain Good morning thank you for the reply I've done a little more tweaking it's a 1.2 and it's flickering 1.1 but as is it's swr 1.2 R=49 X=9 OHM 50
@@rayjohnson7886 I didn't realise you were trying to tune one. How are you measuring it? Right at the feedpoint or via a half wave/s of coax??
@arconeagain Hairpin I adjusted the reflector a little bit the spacing not adjusting the length of it.
@@rayjohnson7886 but where is the analyser being placed?
👋
Yagi antennas are awesome! Good job on the build. What's the bandwidth like on it? I thought about building one a while back and will have to do it. 1 reflector, 1 driven element and 2 directors make decent gain as well.
26-28 Mhz
Very nice! Where did you get the meatl for the antenna elements?
Almighty bunghole unit 23 former unit 867-5309, we just had a qso 5 minutes ago. 73 Paul!. Great setup, i use a inv.vee just 10ft over ground. 9+10!
Hey I’ve talked to you, lol 73s
73's!
Hey Paul, …66 pa 👋🏻
Very nice build !
It's suspiciously the same color as Rachael Ray's hair. Hmmm... If it turns out to be hair, maybe you could get your dog to barf on my head. 😆
Now that you've finished playing around with your 'antenna', your wife says she'd appreciate it if you'd fix the fence and paint the garage doors! 😁 But seriously, the only thing I question is how long it will be before the pigtail attached to the ground side of the driven element (6:29) shorts out on the threads of that u-bolt. You know, with all that rotating and hurricane winds and stuff. Last question: Is that a river or a pond in the backyard, and are there any fish in it?
The fence is gone and I'm getting ready to paint that side of the house lol. That's a pond with nice bass, bream, cats and crappie. I insulated the ground over the U-bolt with coax outer insulator.
@@unit63sc17 Be careful when you do that painting! I heard of one guy who fell off the ladder and almost got hurt, but fortunately he landed in a chair which just so happened to be in the radio shack in front of the radio. Imagine that!
Always nice to see a Diy Beam & good Swr video .....Wow,....1/8" wall thickness Continuous length elements is Really thick !! ...Not exactly best structural design (thin wall telescoping less drooping & better attributes) but maybe more affordable from Local metal scrap yard ? Amazingly Good Swr from simple Direct Connected coax....Thx for video..
Tom - this tubing no droop. Quite stout and excellent mechanical and electrical properties. ASTM grade aircraft.
Hey Paul, Whats up dude ? 019 in Denver !!!!
Hey 019! Pitchers and Catchers reporting! 73's
Great😉🔝🔝🔝🔝
Paul, did you put a rotator on it? If so, which one? Or did you build that too?
I'm using an RCA rotor with no issues. Just make sure you open it up and tighten screws and add locktite. This is a light beam.
I worked on cell sites to several years ago. Ive got about 40 of the silver plated n connectors and i used the lmr400 i had left over on my beam lol its nice to get free parts. good job on the antenna. It’s been a while since I’ve talk to you. 73s WR125 Ky
4-Roger Larry! We should get some conditions soon. I'll be listening for you!
?
Been here since 84 views... I dunno why UA-cam recommend me this... Interesting... Looks like Owl/Eagle Vomit... Looks like Squirrel Fur... Or probably Rare Mold/Fungus from specific material... Never seen those stuff... Hopefully it's not Harmful... Kinda reminds me to Cluster of DaddyLongLegs or Worms...

Hi Paul. That's crazy. Hope the lab results come back and tell you what it is. But it sure looks like hair. That's mad. This is why we Always fed our dog the food we used to eat and she lived to a Great age with no trips to the vets. Great talking to you the other day. Sounding great as usual. 73s. WR456🇬🇧 Rich.
Hi Paul. Great talking to you I believe on Saturday/Sunday. Your were sounding top shelf as always. All the best my friend. Hope we can speak again. 73s WR456 🇬🇧 Rich.
Great job on that antenna, thanks for sharing. Good talking to you last night from up here on the mountains of Montana. Operator Steve-431 Yellowstone Valley Radio.
Thanks Steve - It was my pleasure as well!
Nice Paul, 5650 Scott, Lake Wylie SC
What's up Scott! I haven't heard you in a while. I hope you're doing well.
Nice 4 element flatside dipole
Where do you adjust the SWR?
This is a direct feed with no tuner for swr. If you make it to the specs the swr will be less than 1.5

I'm late to the party, but nice setup, I can verify that it works well! 73 from NM, NB 0149
Thanks Ben. Next project: Modified Moonraker Quad 4! 73's Paul 63SC
nice.. what's that pole foot you used ?
Beautiful! No wonder i always hear you coming into Ontario Canada on top of the pile. 73...... 9WR520 ( formerly 519)
Thanks 520! It was great hearing you in there
Nice one Paul and Happy New Year from your Austrian Buddy Gus 35NB001 😃😃
Thanks Gus! Heard you booming in here the last few days. Happy New Year
