Possibly the best explaination I have ever seen on RUclips.
Absolutely excellent. Your explanation takes a confusing topic and makes it crystal clear! Thank you!
Seriously like never before super awesome thank u so much
Can’t leave without leaving a comment…best explanation ever👏🏽
That makes it easier to understand. Thanks.
Thank You so much for taking the time to put this together and explaining it. You really cleared up my understanding and removed some of my previous assumptions! I had an aha moment!
Simple, elegant, brilliant. Thank you.
Perfectly Explained for Visual Learners! Thank you.
Beautifully explained! What a textbook failed to do, you simply nailed it! Thanks.
A phenomenal explanation
The best explanation I’ve seen, very well done
Thanks, I've been trying to search the web for just this information, but now I understand what DBI means. 👍
This is a small fraction in length vs all the other related videos I have watched and at least 10x more informative and understandable
Best explanation that exists, thank you a lot
clearest explanation in my life
Thank you so much for such a simple and effective explanation🙂
very good explanation and nice animation.
+Gokul p kumar Thank you.

Beautiful teaching. Thank you.
That was an amazing explenation, Thank you very much
Thank you direct and to the point ..everyone should watch your vid before they post anything on you tube
This is an excellent explanation, thank you.
Thank you!
Thank you! Simple and Fantastic explanation of a complex concept. Well done!
Excellent example about the meaning of antenna Gain
Thank you so much for sharing your knowledge in such an easy to understand explanation greatly assisted me in my Network plus exam🙏
very good information, thank you
I saw Best example till now for explaining antenna gain best way of teaching good 😍
Thank you very much for this easy to understand analogy.
OMG, it's so crystaly clear, excellent explanation
Really well presented.. I'm currently putting a lesson together for our sales staff and I hope its ok to show them this video instead of my bumbling though explaining how gain works.
Feel free to do that.
@@solwise Thanks :-)
by the way.. you can find our company at www.comms-spec.com and out youtube channel at ruclips.net/channel/UCu_mFa5A-cUN9bMObTJKEVwvideos
extremely helpful illustration!
very nice visualisation....Very good explanation
You saved me with this video, thanks kind sir
Good example and explanation
Great Explanation, I see that you guys stopped creating videos, Though I dont know the reason but if you guys have the capability to create a video explanation like this I can see that in future you can create more like this and turn it into a science channel, where people can pay you privately to learn more
Thank you this was the easiest explication to understand by far!!!
Very well explained ! Congratulations !
This is a great explanation !
superb explanation
Amazing!
Excellent. Thank you.
just amazing. Thank you boss.
A light bulb isn't an isotropic radiator, because it has a lamp socket which creates a shadow above the lamp and the filament is also not an infinite small point and radiates more light on the side then on its ends. In fact isotropic radiators do not exist, they are just a theoretical construct. Anyway, that's just nitpicking. Everything said was correct and the explanation is a very good one! I use the light bulb analogy myself when I explain this to someone.
such an easy way to understand , very effective
very good explanation... thank you
can't find best explanation than this.
Excellent, quite simple and understandable and this is what we need 👍
Thank you so much.....could you please replace the bulb with patch antenna, that would be more informative ...
We will have a conclusive on how to increase gain while designing the patch antennas ..
Appreciate your help
That was beautiful.
excellent explanation. thank you.
Awesome visuals bruddah thank you! ✌️♥️💯
good and easy explanation. Thanks :)
damn 2019 and this Video is rly good take my like
Thank you.
Thank you so so much
excellent explanation!
Superb man...superb
Thank you so much
Well done!
amazing explaination. have a great day
thank you!
very well explained
Thanks for the video, that was very helpful =)
Best visualization of gain I have seen. David Byrd KN4BHS
thanks man .. very good explanation .
best explanation ever thanks
awesome
really nice clear explanation - thank you !
Excellent +++
Nice explanation
nice animation thanx
Super explanation
got it
The fuck did I just watch? was it this easy to explain? you sir have just won a subscriber
i used to explain to people that a lot of things in physic can be explain in other type of form using other material or physic to understand it easier. just like if you amp up the power way too much it doesn't really improve the signal as much compare to the antenna itself. it might disrupt the listener. i relate it to screaming. if someone talk normally you can hear the words clearly. but if you scream the words next to your ear, its harder to hear it clearly. in some case, giving too much power disrupt the quality of signal.
mannnnnnnnnnnnnnnny info in simple way thanks a lot
If you now if my right tinhg yuo now
Yes yes, very goo explanation
Maybe the best video for the (Antenna Gain ) on youtube!
awsome explanation
Thank you very much.!!
I don't get it. Does this have anything to do with my gain knob and if so, what is it doing?
Nice animation work you have done here.
You could go true a complete radio amateur course with this animation work and make the boring stuff, less boring.
After gain, will the antenna be Omni directional?
Yes I'm so glad you could talk to me like I was four years old because I wouldn't get it if you wasn't talking to me like a child
Very nice explanation! Thanks
thanks a lot for that explanation, i have another question about dBi, it is written on the Antenna, that mean, each Antenna has own dBi.
Nice explanation.super.can pls show how to make Yagi Uda Antenna.i want to learn from u pls.tq.
Please explaining antenna arrays radiation pattern this way
We learnt if we gain more db then directivity will be narrower or less coverage ..
excellent
I did not undestrand the 6 gain,why 6?
narrow beam radar detect stukas and v1s approaching english shores
Superb man
Then how would we know by seeing the antenna that which side is it focusing its waves? Will the user need to put receiver antenna in same direction mandatorily as the transmitter antenna has gain in one direction!?
Identifying Orientation: I'm not sure there is a generic answer to this question, antennas come in all shapes and sizes. If it is not obvious try searching for an arrow somewhere on the antenna, otherwise consult the manual.
Selecting Orientation: If the link is point-to-point then the two antennas should be aimed at each other. For point-to-multipoint then the central antenna should be omnidirectional and each endpoint shoul be aimed at that.
Hope that helps.
Its a good explanation, but the equation could provide a better understanding
So if it's all about focus, how does a higher gain antenna help if it's the exact same shape?
Like trading the stock unit for a "high gain" antenna that looks pretty much the same.
Excellent.
👍👍👍
Loving the explaination... until mind melted at 1:38. 3dBi = 2... arrgh haha
I love you!
Very nice explanation. i still confuse the term "dBi" and "dBm", some wireless adapter state "
OK, dBi is a figure which expresses gain over an isotropic antenna (which has a gain of 0dB). dBm expresses a signal power compared to 1mW, so 100mW can be written as 20dBm. I think the video describes the units better than I can in words here.
Now, your floors. My video shows operation in free space. Lets imagine the situation of our high gain parabolic light-bulb antenna which focusses all the available power into a pencil-thin beam. Point this out of your window and we might get our signal to the moon. Point it at the floor and we'll get our signal a far as the floor.
This brings up two issues:
1. Will our signal go through the floor? Our light-bulb antenna will not penetrate the floor but how will your WiFi signals get on? Well, if your floor is made of concrete you can expect at least 20dB of loss passing through it. If your floors are made of wood and plasterboard expect a loss of 3 to 5dB. (But beware foil-lined plasterboard or insulation which will totally reflect the signal.)
2. What direction should we point our antennas? If we pointed our pencil thin beam of light across the street into our neighbour's window and it landed on his white-painted wall, it would probably illuminate his room quite effectively as the light scattered off his wall. Note that if his wall was painted black the situation would be very different. So the question is: How do our WiFi signals behave in this reflecting/scattering effect? Broadly speaking the effect is similar to light and also dependent on the materials (though not colour). 5GHz WiFi tends to reflect more than 2.4GHz.
We should learn from these two effects that raising the gain of indoor antennas is usually fruitless unless we can predict the route the signals will take between the endpoints, which we usually can't.

Solwise Paul Well thank you for your explaination, i get your point.
Welk Dome & thx
