the best explanation with absolute clarity

[bramfran]

This is probably the clearest explanation in YouTube of how antennas work.

This is an amazing video!!!! I've been working in IT for years and I've seen the charts for the antennas I've used in the past, but never really understood with clarity what they meant. This was immensely helpful.

Yo, this is god-like material. Thank you! Can’t believe it’s free!

[insertname]

amazing video, I'll show this to any new student of antennas!

[videosdojairo]

The animations used are really good, as the whole video. Well done!

[th_dwarf]

I'm a physicist, so not much new knowledge to me, but very good animation and didactic way of presenting the subject. Thank you for the effort and letting people get acquainted with this huge topic.

Nice animations. Fine primer for people who aren't in electronics.

Electronics brain is asking what about the analogue of space as a transmission medium with characteristic impedance, as with any other transmission line, and how impedance matching is important, and how the length of the antennas are usually a bit different than calculated due to the self inductance of the transmitter... Reflections. Noise. Side bands. Near and far fields. These are just off the top of my head. Nice animations.

I'm not complaining. But I have been searching for a long time to see a good video describing near and far fields and lossy transmission lines. I want to learn more of that in like granular detail. There is some tech I worked with, long ago, and now I wanna know how it worked exactly. The work was for a communications company in the Arctic (a weird place).

The video is great. I have been in the communication tower business for over 20 years and don't know any tower dog that knows this. 😂. I own and operate a small communication tower contractor and mainly install equipment for Verizon and AT&T. I want to use this video for training purposes in the future.

[shujaathussain]

Thank you for such a nice video about antenna,
animation, audio quality and voiceover, are very good.
Learning or knowing the " mysteries of radio ", and science was never so easy before.
Jazakallah.

subscribed, really it solved my many queries
an amazing video

[teimurazkortua]

Thank you for such a nice video about antenna.

[borisbadinov]

TRULY a great video. Thank you for this. It explains what is in my head, but I cant relate to my friends. Well done!

[rakfmtowertransmittersite]

Keep up this good work!!!I would love to watch more upcoming quality videos...I have subscribed already now because of the quality of knowledge of concept that you provide through your videos.Thankyou so much!!!

Actually the method by which "radio waves" travel is photons. Alternating charge acceleration (voltage) in a metallic object produces photons as the electrical charges expand and contract just like doing the same produces light via mercury atoms in a fluorescent lamp. Radio reception is achieved when the photons interact with metallic objects and turns photon absorption into expansion and contraction in the antenna, thus producing a reverse of the alternating charge acceleration in the transmission mode. Charge acceleration is detected and the alternating voltage amplified, processed and the output turned back into meaningful information.

[randall.chamberlain]

Sorry but despite the general concepts being accurate, this explanation is misleading as it makes it look like local magnetic filed is the same as the magnetic field of the wave. They are not the same. The magnetic field fades very quickly form the source so I would never be able to influence a remote receiver. It is the electromagnetic waves that can actually propagate. This a subtle but crucial difference

Outstanding video! Thank You a lot! ❤👍🏻

I learned so much from this. Thank you for sharing this wonderful knowledge :)
