Yagi Uda Basic Design and Construction | Easy Antenna Tutorial

[@fontesdeo8582]

Excellent tutorial. I appreciate how thoughtful & intentional you explained this.

[@575600]

Sir You always explain the video so well. And conclusion you make at the end of the video is always awesome, thanks for uploading.

[@nipunharitash]

Thank You Sir for the kind words !!

[@Lorentz1975]

are reflector, dipole, directors and boom stick insulated or are they in short?

[@nipunharitash]

insulated

[@Lorentz1975]

@@nipunharitash I connect the inner pole of the coax cable with the dipole and the external gauze of the coax cable with the reflector isn't it? Thanx

[@PhantomWoIf]

Lorentz, NO. the cable is connected only to the folded dipole, which is the driving element. The cable is *NOT* connected to the reflector and neither the directors.

[@billpowell5931]

Very good explanation. Thank you for sharing.

[@peterzingler6221]

Does the diameter of the elements matter much?

[@nipunharitash]

Its is said to keep it negligible as compared to lambda

[@jaysontiauzon8493]

CAN I ASK QUESTION ? HOW ABOUT ON 7 ELEMENTS ?

[@md.al-imranabir2011]

Thank you for the tutorial. It would be great if you could provide the link of the next video in the video description or in pinned comment.

[@nipunharitash]

Oh Ok

[@JohnDoe-ed7vw]

Why does a metal part behind the driven element reflect while the metal parts in front the driven element support the wave, how does same type of metal do different actions?

[@nipunharitash]

The answer in the mathematics of principle pattern multiplication

Great Explanation of basic Yagi Design.

Appreciate that

[@garycook5125]

What does "C" represent in your formula?

[@markg7030]

He answered that 5 years ago and said C is the speed of light.

[@garyabc]

Very good explanation. Thanks for putting this video together.

[@nipunharitash]

Appreciate that

[@pauldelany-g7p]

For someone building their own yagi,,how critical is it that each element is directly in line please??,

[@sebidsouza4029]

Sir do u have Yagi antenn circuit diagram of 2 unit booster ,one was attach itself to the antenna and other unit was it's power supply

[@nipunharitash]

No, sorry

[@madware]

when you calculate the 2nd director length you say: the 2nd length= 1st director - 5% the 1st director, but you writed 1st director -5% dipole length, which one is right?, thanks in advice

[@nipunharitash]

First one , the length is 5 percent lesser than the previous element :) Thanks for pointing out though

[@madware]

@@nipunharitash thank you so much for the quick answer, i was thinking that the first one was correct, great video ;)

[@davidbee3704]

I had the same question. Thanks for asking it and thanks to the author for answering it

[@venkateswarlugujjula4015]

Nice video. Thank you sir. How to chose radius of elements? and the gap in dipole to give excitation/source?

[@nipunharitash]

Hello, I'm not sure about the meaning radius here. If you mean the length of elements it's progressive .I'm not sure about the gap between length of wires where we connect the source.

[@venkateswarlugujjula4015]

Dipole we are taking here is of cylindrical shape. I am asking the radius of cylinder

[@StrsAmbrg]

@@nipunharitash what is the space between the two pieces of the driven elements, and the size (diamater) of the elements? Will be same if we use big size element and if we use small element?

[@davidjames1684]

This is just a guideline. Different spacings can be made to optimize radiation pattern, impedance.... Also there is no maximum boom length for these antennas. Whatever is physically possible can be built. A 100 element Yagi for example is certainly possible, but would need to be supported in more than just 1 place. I have seen long Yagi go across a rooftop of a building for example.

[@nipunharitash]

Hello, the video is intended to familiarize undergraduate students to arrays. Appreciate feedback :)

[@tld8102]

very helpful mate. but i’ve been thinking of making this out of copper tape so it is flat (aim: to transmit video off a flying rocket). must my concern is because i would be using copper tape which might be considered a patch antenna… i’m new to this… a bit confused

[@m.sharathreddy4356]

what is the boom length formula?

[@nipunharitash]

add distances of elements

[@jspalding70]

Thanks for the information. Have you make antenna which is about 40 mil. I am trying to develop a UHF frequency: 902-928 MHz antenna. If you have any advice please share.

[@nipunharitash]

Hello. I taught this subject at undergraduate level a few years back. I'm afraid I have no exposure in fabricating or developing physical antennas in lab.

[@gingerelvira6587]

Google searchfor one

[@ThatEEguy2818]

You gave the spacing between the dipole and first director, but what about 2nd director and so on? Also, how wide should the dipole be (spacing from top to bottom of loop)? How thick should the elements be and what effect does it have if you vary them? How far apart should the connection of the dipole be?

[@nipunharitash]

I'm gonna have to look for those as well and append them in a new video. This is an introductory theory undergraduate lecture but sure those parameters matter in real design

[@mharinathreddy8262]

Thank you 😊 I loved this video

[@kokfahchong1867]

Yagi-Uda antenna has such shape and size is to facilitate the "free" flow of free electrons that first directed towards driving element where photons will be dissipated out once they have reached the dead end of the driving element. Since reflector is longer than driving element and those directors, it is perceived to have highest resistance. Flow of free electrons will tend to flow in less resistance path. Therefore most of remnant of free electrons from driving element will flow towards the directors instead of reflector. Some free electrons will flow into the first director and photons will be dissipated once they have reached the dead end of the director. Then fewer remnant free electrons will flow into the next director with lower resistance with shorter length. Dynamic photons will dissipate to the surroundings after those free electrons have reached the dead end of the director. Even fewer free electrons will flow towards the next director with shorter length with lower resistance. Fewer photons will be dissipated out from those free electrons upon reaching its dead end. The ways dynamic photons being dissipated out from the yagi-uda antenna will be shaped them like a "loop" of directional dissipation of dynamic photons. Since driving element will dissipate out abundant photons, first director will dissipate out fewer and second director will even dissipate out even fewer photons and so on as if those dissipated photons will mold into a directional dissipation of dynamic photons. Therefore Yagi-Uda antenna will emit out directional dissipation of dynamic photons. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

can you help me, is this a multiband yagi? (www.amazon.in/Gleam-Tech-Antenna-Mobile-Booster/dp/B07CRS6MPM) With my bit of knowledge, it's hard to build yagi with wide range! how can they tell its wise band :) little worried! is it true?

[@humbertopvillalta6383]

Me parece muy buena introducción básica. Congratulations, Gracias.

[@amreshchandra]

Nice one mate :) Thanks for uploading this

[@damnthiccassboye7138]

Can you tell me what is .2 lambda

[@nipunharitash]

Lambda is the operating wavelength of the antenna and .2 lambda represents 1/5th of wavelength :)

[@damnthiccassboye7138]

Nipun Haritash oh thanks man

[@prashantrayamajhi5979]

What is the formula to find length of boom stick? and is the spacing between all the directors equal as (0.125 lambda)? I am working with 5.875 Ghz frequency.

[@nipunharitash]

Yes, The director-director and director-antenna remains same at .125 lambda, reflector- antenna length is approx .2 lambda, i dont remember boom length figure, please see and use yagi uda calculator tutorial for exact figures for your frequency of operation.

[@maximilian200057]

Your lambda is flipped.

[@nipunharitash]

The limitation on yagi is from the Boom Length's point of view, Please see max boom length and consequently the spacing between elements depends upon wavelength.

[@ColeDedhand]

This is my BOOM STICK!

[@isntimportant]

There's no maximum length to the boom stick! Boom sticks should be as big as you can carry! :P
