I have seen various youtubers trying to teach about ANTENNAS, but you really know this profoundly and share it whith us. Every minute is golden Thank you!
Antennas fascinate me. I have made a 450. Mz Yagi that many elements. This antenna was near five feet long. I hooked to my police scanner. And pointed it toward a city that was close to 35 miles away. I received their radio transmissions perfect. I only listen to Union Pacific railroad traffic now. I made a quarter wave dipole and it receives beyond my wildest expections. The antenna is standing in my bedroom. I have a Uniden BCD536HP. The antennas, telescoping and rubber duck antennas are like having no antennas. The railroad works on two meter 161.265 Mz most of these stations are 35 to 40 moles. Keep up the great videos , I have subscribed. Curtis
Pedagogy at its finest, this man just does not only know the subject by heart, he also radiates the information in the most resonating way that our brains can perceive. Mate, my lecturers at uni has lot to learn from you honestly. Good work. Appreciate the enthusiasm.
Pedagogigally this is not as simple as you perceive it. In YT global audience this is a bit too fast language. I appreciate the knowledge presented in this video but it is not pedagogigally at potential.
The frequency of delivery resonated with my pace to follow. The direction of the content was just what I wanted to know. Transmission received, sir, and it is my gain.
Spent several years at Purdue and never had a professor quite this enthusiastic! Thanks for the great content, it was well appreciated and truly enjoyed!
Your explanation of antennas and radio signal polarity was excellent. You presentation of antenna theory was better than I have ever seen and read. Keep up the great work. Cheers from your neighbor across the pond.
This is the first video I'm watching about this subject with little knowledge in advance and I'm understanding so much all thanks to this great gentleman and his awesome way of teaching . Can't thank you enough sir .
I play with antennas for years even go to school for it still i don't understand as well until i see your video. Yeah still watch video for it till this day. Thank you much.
After nearly a lifetime of trying to figure out how transmitters and antennas work, you sir have helped immensely. Although there are still holes in my understanding, I have subscribed to your channel and plan to watch many more of your videos. Thank you very, very much!!!
I wish he was reading children's stories, well i guess he is..I enjoy his presentation, sound fx and all, Im also a mature age first year engineering student
Ricardo yeah i had a professor like that what i have found in my time is this there are people who know certain bits of information, but then there are bits they don't know. how you tell the difference is this... When one can explain something simply, it means they clearly understand it, when they stray away from their normal use of words and tend to speak quicker or use words that are more complex it usually means they don't understand the subject. a good example of this in I.T. is this.. ask a technician does he know how a hard drive works hehe he'll likely say.. he does then ask him to tell you step by step starting from the CPU, and assuming the CPU is sending data to the hard drive ask him to explain *Every single Step* that the data takes and what when this happens he'll tell you the data gets to the SATA port where the drive is connected it goes up the cable HEHEHEEHE and then something something in the middle here, that he skips over and........ hoping to god you didn't realize he then says the data is written to the hard drive platter now.. if you pull him up and say hang on... so... from the SATA Port on the back fo the hard drive, HOW EXACTLY did the data make it to the platter LOL it's funny when this happens but yeah that's how you tell if a person skips something, Purposely make a point of slowing them down you'll usually find they have gaps in their knowledge but when there are no gaps, it comes across like this guy is saying it, i pride myself on filling my gaps and it's awesome when someone like this comes along, I've been fortunate to have around 7 of them thus far that have taught me that's why i know what i know. be cool mate
50 yrs troubleshooting security systems .... ( that are turning to miniature / micro radio transmitters like crazy ) I ve done much projecting ,( some successful ...others not ) trying to increase transmitter out put and or receiver gain . I wish I could crawl inside your head ,because you have an easy to follow and great wealth of R F knowledge ...I love this !
Many years worth of accumulated knowledge transmitted, received AND understood in slightly more than half an hour. Now thats some antennae you're using ! Thank you.
This man made me feel more welcome to his whiteboard video than my family has made me feel during this quarantine. This video was a perfect mix of comedy with knowledge. Arigato.
Hi there, when I was a small boy, now an old man, I used to make my own crystal sets and I played around with bits of wire to get a signal. One wire outside, a long one, and another fastened to my metal springs on my bed. Some days, I was able to get wonderful reception and others very little. All my life, I have wanted to know why that was and now, after watching this video, I have a good idea how things work and I thank you for explaining and teaching this to me. I do not profess to understand every little detail, of your teachings, but it is wonderful that now, at long last, I know the basics and I cannot thank you enough. John.
Great practical explanation of antenna theory and operation. This is sufficient for most people to understand the basics. Really good explanations boil down the theory to the most essential parts without getting bogged down in the details or too many equations. It would be great to see this introduction video followed up with actual examples with a bit more theory where the numbers are plugged and secondary effects of the antenna geometry, cabling, and circuit connections are addressed.
Speaking as a raggedy-arsed mechanical engineer, I found this talk to be an easily understood refresher in electromagnetics and for the first time have some appreciation of how antennas work. The descriptions of monopoles, sleeve dipoles and yagis was easily understood. It took me a bit by surprise when you started talking about radio-controlled model aircraft - another activity I indulged in years ago with minimal success ! I minor quibble, it would have been helpful to remind the viewer of how decibel numbers work. I recall that the dB number is a log-based ratio but forget the conversion to non-logarithmic numbers. Thanks for a great presentation. Good-on-ya mate !
Some of this was review for me, but it was so well taught that I have watched this video in its entirety and I am subscribing to learn more. Well done! We need more teachers and professors like you.

Speaking of energy; This man is several times my age with several times the energy. I gotta step it up! Wonderful video, great examples, and the way you step through the neccesary info to lead us into the big picture and then general application is great, I left this video smarter.
Your not boring at all. And I am studying for my amature radio extra class license here in the U. S. This video was exciting and helped me understand antenna theory, so I can now better pass my test, because I watched this video. Thank you.
I've been dealing with electronics for about 45 years now but had forgotten a lot of what you covered here. Your presentation is very good and no, I didn't sleep... 🤣 Looking forward to more. Thanks!
Thanks for the refresher! I haven't heard the term 'Yagi' since my school days... The best example of Yagi antennas is the old roof-top TV antennas that were used to capture a VHF signal from your local TV station. If you were fortunate enough to have a rotor, then you could turn a dial on a set-top box and a motor would spin the TV antenna accordingly, allowing you to pick up TV stations in that direction... Thanks for posting this detailed video, and JUST SO YOU KNOW, I didn't fall asleep! ;)

Best explanation of antennas I have EVER watched (and I "learned" telecommunications at university). Thank you very much for the video!
Your method of communicating to the unknowing, is excellent; I'm glad I experienced your skills. I think I may actually understand your antenna theory now! Thank You.
Your video is amazing. I’ve been in the ham radio game for 27 years and This is the best visual demonstration I’ve ever seen. I just don’t get why people don’t find this stuff amazing.
You are an AMAZING teacher! Thank you very much for this lesson. I’m starting from scratch to educate myself in this subject. Always thought it was a difficult matter, but you made it so clear and easy to grasp. Good luck and Blessings to you!
I agree completely with this comment. I’ve visited this topic several times in the past, walking away thinking, “this is the most complicated thing I’ve ever encountered”. This video has given me back the confidence to dive in again.
Thank you, thank you, thank you.... It only took eleven minutes of your video to allow me to understand why the 'dynamic braking' (I should have said, 'regenerative braking') on my hybrid Rav4 works. I've been pondering how it actually makes the vehicle slow down for YEARS.
When I was young the CB radio was the Fad of the day it was a perfect hobby for me. But I soon found the usual 5watt CB radio with numerous channels (different frequencies) work better on some & less on others so I became very interested in building my own dipole antennas using plastic covered metal curtain rods with three legged ground planes. I became engulfed in the technology of antennas & spent a couple of years experimenting building my own power meters, frequency counters and standing wave meters etc. It was a very interesting hobby & I learnt a great deal.
Hands down, the best bloody presentation I've ever seen. Wish I had a few professors with your style when I was in coll. for the same subjects. Love to hear your take on traveling wave tubes. KUDOS , take a bow and a pint after that
Sir, you have a natural teaching talent. I was far from being bored. Thank you for that video and I’m looking forward to watching your other and future videos.
I knew nothing about how radio transmission worked. Honestly I don't even know much about electricity so I thought I would get lost watching this. However, this video is amazing, and I didn't get lost at all! I know so much more than I did 30 minutes ago. Thankyou!
With a physics teacher like Bruce, how can I afford to fall asleep? After watching this wonderful presentation I am now more informed on how antennas work and i can even make one. Thank you.
Been a HAM since '78, and have built dozens of antennas, and even did moonbounce with an OSI 6502 controller back in the 80s, but have never heard it antenna function put so well as "more metal in the game". I sure wish somebody had said it so clearly back in my college days, but even the professors didn't cut thru the BS like you do here. Keep up the great work! I may just start bending welding wire again... Scott
I just started CB home unit with a Nice mint in box old Kenwood...Im using a 5foot car antenna on a 30ft pole in yard... What antenna and or device can i use to Reach Out a Little more.. on a good night i can Receive/Transmit 20 Miles.... Will a Bigger antenna make a Difference?
I think a lot of this video is rules of thumb for RC pilots that aren't 100% accurate. Radio waves aren't actually sine-wave-shaped in space. The reason polarization is important is not because of the area overlap. It's not *just* about having more metal, it also has to be shaped correctly.
You know you were mentioning about a moonbounce I did not have a ham radio license when I was a kid but in the 1970s I played around with the 11 meter band and don't a large Moonraker duplicate beam that was the name of a manufactured brand that I duplicated and I'm horizontal I used to do a moon bounce by just putting a site level on the antenna and aiming it at the Moon didn't really know where was going to end up I used to just see who answered me
Scott Marshall hi sir can I ask you a quick question? Is it possible to transmit/relay a LF signal from the source by using a non attached cable with a loop antenna or how can you amplify a LF signal? Sorry if that don’t make much sense I’m not a expert
@@thewhitefalcon8539 there is a disclaimer at the front of the video... saying he had to take some liberties to make it understandable to a wider audience. Most hobbyists don't GAF as long as it works... yes, I agree with you because I've made my living as an electronics tech my entire life, but this vid is indeed a really good explanation of the theory.
@Science Revolution This was what I wanted to find out and I was hoping he would explain. It is such an obvious question. Having explained about electromagnetic induction in terms of current flow there is no current flow in an open ended antenna
Profound thanks. Finally, I can see the interrelationships between EMF, transmission and reception, linear vs helical antennas, and especially all of these in harmony with AC, resonance, pendulum harmonics, RH vs LH helices and their inability effectively communicate. OMG. I'm an emeritus prof (mirobiology, molecular and general genetics, cell biology, physical and theoretical biophysics) with hobbies in electronics, radio, etc. You just tied the prettiest bow on my neverending quest. Thank you. Thank you. Thank you.
Fantastic explanation - engineer of 40 years who never understood antenna theory (must have been sick that week at uni). Can extrapolate that to phased array antennas, where the signal superposition is managed electronically.
These are the type of videos you excel at. very informative, I learned a couple of things thank you. Much better than the ranting about regulations etc
Ah I finally get it, thank you so much, I feel like I won a years worth of knowledge in one class. Serious I would pay for a semester with cost of books,reading, all the trips back and fourth and pray at the end , I learned and understand as much as I understand today.
LOL - being a former microwave technician 40 years ago (including earth stations w/30M dishes), I got engrossed watching your presentation. Towards the end with your excitement, I went to the TH-cam gear to slow the video down from 2x back to 1x speed but found you were ALREADY TALKING AT 1x SPEED!!! Yo the man, Bro - thanks for sharing :)
Brilliant, just brilliant. This has triggerred me to rethink what I 'thought' I knew already. It is always very difficult to portray a subject that acts as a 3-dimensions array in the real world, but then to attempt to teach the subject on a 2-dimensional wipe board. For example a helix spiral of wire such as the circular polarized antenna in one view (i.e. end view) is a just a circle, in the other two views (i.e. side view, and top view) you see a sawtooth/sinusoidal waveform drawing each one 90 degrees our of phase. All this information that the human mind needs to re-compile in real time to absorb and understand. Superb video 😊
I thank you sir for making my head explode with knowledge on a subject that has had me perplexed. Coincidentally earlier at work today, I ordered a triplexer on ebay. I want to see if anything good happens if I connect three crappy antennas to one tv by facing one antenna north, one south, and one west. My house is pretty much as east as you can get without falling in the ocean so I assume all the broadcast towers are coming from the other 3 directions. I'm sure they'll be out of phase and cancel each other out but the answer is always no if you don't ask, so I'm giving it a go. It's a $5 investment so I'll survive if it fails. Great video of you I stumbled upon. I'll be sure to watch much more. You are a credit to your profession, whatever that may be.
About as far from boring as is possible. I'm now going to go to any other links you have to any other videos of yours! I feel I learned a lot! Thank you!
I remember watching this years ago and finding SO much value in it! Your work truly helps the hobby! (Now I enjoy your videos at the airport with your friends the most. Such great fun and good people). My wife and I travel a lot so I'm adding a trip out there to my bucket list. She's not in the hobby but she's sat through enough of your videos that she'll get along just fine :-)
I have an interview for an RF engineering role next week. This video was a great refresher for what I learnt at university. You have a great teaching style.
I just got my first function generator. It's just a little $100 thing based on an FPGA. But ever since getting it I've been overwhelmed with thoughts of all of the different experiments I can do with it. One such experiment I wanted to try is to transmit and receive radio signals. So video lectures about antennas and practical RF design are really useful in helping me to realize that goal. Since I have no experience with RF at all. Before I got my function gen, the highest frequencies I'd work with were
genius explanations, truly a great communicator. I watched the whole thing. I love the enthusiasm and humor. Thank you for one of the best lectures i have ever seen.
The scientific inaccuracies as mentioned in the disclaimer at the start are very few actually. This video is a fairly correct explanation of antenna behaviour.
I've learned so much from this gentleman. It wouldn't have surprised me if he wasn't a teacher at some point in his career. What a goldmine of information. ♥
What a great explanation of antennas! I've just started with amateur radio and have built a couple of antenna's and this is the best explanation of how they work!
Thank you very much for this video. I have been looking for a video that explained antennas that started from the very beginning and did not assume antenna knowledge and this is the video that helped me understand. Your starting with a demonstration with the magnet and the multimeter helped tremendously for my understanding of what was happening between signals and antennas. Thank you very much!
You make a very good instructor! When I was in school I would turn to TH-camrs like you if I did not understand something in class. I am studying to get my hame license. And you are doing a very good job of educating me!
It all boils down to what you need. Direction, distance, latency (latency if you go through a third medium like satellite or other). If you detract the maths, basically all what I have learned in the uni... thank you for your great explanation. GREAT WORK of free study!
Just came across your video while looking at WiFi systems. Wish I'd had you as my Uni lecturer years ago, you explained it all so much clearer and quicker!!
You're an excellent teacher, fixed my attention on the subject, learnt a lot from it and boost it with comedy ( bing bing bing ) giving your audience great recall ! UNDERSTAND IT WELL, THANKS from your avid follower from the Philippines !
What makes this good video even better is that there is no LOUSY LOUD BACKGROUND MUSIC. Thanks!
Indeed.

You're the person I send people to when I need to show them how things work. Some of the greatest teaching I've ever witnessed!

Ricardo
yeah i had a professor like that
what i have found in my time is this
there are people who know certain bits of information, but then there are bits they don't know.
how you tell the difference is this...
When one can explain something simply, it means they clearly understand it,
when they stray away from their normal use of words and tend to speak quicker or use words that are more complex it usually means they don't understand the subject.
a good example of this in I.T. is this..
ask a technician does he know how a hard drive works hehe
he'll likely say.. he does
then ask him to tell you step by step
starting from the CPU, and assuming the CPU is sending data to the hard drive
ask him to explain *Every single Step* that the data takes
and what when this happens
he'll tell you the data gets to the SATA port where the drive is connected
it goes up the cable
HEHEHEEHE and then something something in the middle here, that he skips over and........
hoping to god you didn't realize he then says
the data is written to the hard drive platter
now.. if you pull him up and say
hang on...
so... from the SATA Port on the back fo the hard drive, HOW EXACTLY did the data make it to the platter
LOL
it's funny when this happens
but yeah
that's how you tell
if a person skips something, Purposely make a point of slowing them down
you'll usually find they have gaps in their knowledge
but when there are no gaps, it comes across like this guy is saying it,
i pride myself on filling my gaps
and it's awesome when someone like this comes along,
I've been fortunate to have around 7 of them thus far that have taught me
that's why i know what i know.
be cool mate

But I soon found the usual 5watt CB radio with numerous channels (different frequencies) work better on some & less on others so I became very interested in building my own dipole antennas using plastic covered metal curtain rods with three legged ground planes. I became engulfed in the technology of antennas & spent a couple of years experimenting building my own power meters, frequency counters and standing wave meters etc. It was a very interesting hobby & I learnt a great deal.
The best thing to listen to amazing. Trying to hear what's being said.

TH-cam should make this video mandatory for every creator to watch and learn how to explain a topic.
The best lecture I ever seen, spite being on my third and last year of my bachelors. Please make more videos like this, I loved it 😄
Hands down, the best bloody presentation I've ever seen. Wish I had a few professors with your style when I was in coll. for the same subjects. Love to hear your take on traveling wave tubes. KUDOS , take a bow and a pint after that
Sir, you have a natural teaching talent. I was far from being bored. Thank you for that video and I’m looking forward to watching your other and future videos.
I knew nothing about how radio transmission worked. Honestly I don't even know much about electricity so I thought I would get lost watching this. However, this video is amazing, and I didn't get lost at all! I know so much more than I did 30 minutes ago. Thankyou!
Excellent class on antennas!
Wish I had a teacher like you.
With a physics teacher like Bruce, how can I afford to fall asleep? After watching this wonderful presentation I am now more informed on how antennas work and i can even make one.
Thank you.
Been a HAM since '78, and have built dozens of antennas, and even did moonbounce with an OSI 6502 controller back in the 80s, but have never heard it antenna function put so well as "more metal in the game". I sure wish somebody had said it so clearly back in my college days, but even the professors didn't cut thru the BS like you do here.
Keep up the great work!
I may just start bending welding wire again...

I just started CB home unit with a Nice mint in box old Kenwood...Im using a 5foot car antenna on a 30ft pole in yard... What antenna and or device can i use to Reach Out a Little more.. on a good night i can Receive/Transmit 20 Miles.... Will a Bigger antenna make a Difference?
I think a lot of this video is rules of thumb for RC pilots that aren't 100% accurate. Radio waves aren't actually sine-wave-shaped in space. The reason polarization is important is not because of the area overlap. It's not *just* about having more metal, it also has to be shaped correctly.
You know you were mentioning about a moonbounce I did not have a ham radio license when I was a kid but in the 1970s I played around with the 11 meter band and don't a large Moonraker duplicate beam that was the name of a manufactured brand that I duplicated and I'm horizontal I used to do a moon bounce by just putting a site level on the antenna and aiming it at the Moon didn't really know where was going to end up I used to just see who answered me
Scott Marshall hi sir can I ask you a quick question? Is it possible to transmit/relay a LF signal from the source by using a non attached cable with a loop antenna or how can you amplify a LF signal? Sorry if that don’t make much sense I’m not a expert
@@thewhitefalcon8539 there is a disclaimer at the front of the video... saying he had to take some liberties to make it understandable to a wider audience. Most hobbyists don't GAF as long as it works... yes, I agree with you because I've made my living as an electronics tech my entire life, but this vid is indeed a really good explanation of the theory.
Just got my Technician License for amateur radio and thought this video was very educational and cleared up a ton of questions I have
Excellent presentation and teaching skills. I watched the entire video, never knew that this topic could be interesting. Thanks for posting.
Get off the meth TH-camHitler
@Science Revolution This was what I wanted to find out and I was hoping he would explain. It is such an obvious question. Having explained about electromagnetic induction in terms of current flow there is no current flow in an open ended antenna
This is the clearest radio wave exp. I have ever heard... This man is a genius.
This is definitely the kind of videos which makes me love RCModelReviews all over these years
Absolutely!!!
Profound thanks. Finally, I can see the interrelationships between EMF, transmission and reception, linear vs helical antennas, and especially all of these in harmony with AC, resonance, pendulum harmonics, RH vs LH helices and their inability effectively communicate. OMG. I'm an emeritus prof (mirobiology, molecular and general genetics, cell biology, physical and theoretical biophysics) with hobbies in electronics, radio, etc. You just tied the prettiest bow on my neverending quest. Thank you. Thank you. Thank you.
That helped so much. All the terms I had been hearing but didn't know the meaning of were covered. Thank you.
Fantastic explanation - engineer of 40 years who never understood antenna theory (must have been sick that week at uni). Can extrapolate that to phased array antennas, where the signal superposition is managed electronically.
One of the best antenna tutorials i've seen. Great!
Best explanation of how an antenna works that I have seen! Nice job professor!!
These are the type of videos you excel at. very informative, I learned a couple of things thank you. Much better than the ranting about regulations etc
Ah I finally get it, thank you so much, I feel like I won a years worth of knowledge in one class. Serious I would pay for a semester with cost of books,reading, all the trips back and fourth and pray at the end , I learned and understand as much as I understand today.
Bing bing bing bing! Best "how antennas work video" on TH-cam.
LOL - being a former microwave technician 40 years ago (including earth stations w/30M dishes), I got engrossed watching your presentation. Towards the end with your excitement, I went to the TH-cam gear to slow the video down from 2x back to 1x speed but found you were ALREADY TALKING AT 1x SPEED!!! Yo the man, Bro - thanks for sharing :)
Excellent video! I really appreciate the effort that you put in. You have a knack of explaining things that doesn't fly over the viewers head. Thanks.
Brilliant, just brilliant. This has triggerred me to rethink what I 'thought' I knew already.
It is always very difficult to portray a subject that acts as a 3-dimensions array in the real world, but then to attempt to teach the subject on a 2-dimensional wipe board. For example a helix spiral of wire such as the circular polarized antenna in one view (i.e. end view) is a just a circle, in the other two views (i.e. side view, and top view) you see a sawtooth/sinusoidal waveform drawing each one 90 degrees our of phase. All this information that the human mind needs to re-compile in real time to absorb and understand.
Superb video 😊
Its the first time in my life when watching educational video i didn't skip a single time.
I thank you sir for making my head explode with knowledge on a subject that has had me perplexed. Coincidentally earlier at work today, I ordered a triplexer on ebay. I want to see if anything good happens if I connect three crappy antennas to one tv by facing one antenna north, one south, and one west. My house is pretty much as east as you can get without falling in the ocean so I assume all the broadcast towers are coming from the other 3 directions. I'm sure they'll be out of phase and cancel each other out but the answer is always no if you don't ask, so I'm giving it a go. It's a $5 investment so I'll survive if it fails. Great video of you I stumbled upon. I'll be sure to watch much more. You are a credit to your profession, whatever that may be.
Thank you for making the video! This is the most accessible introduction with examples that I could have asked for. Super helpful! Thanks!
About as far from boring as is possible. I'm now going to go to any other links you have to any other videos of yours! I feel I learned a lot!
Thank you!
Great video, you explained a difficult subject in an easy way and that's hard. Thank you.
I remember watching this years ago and finding SO much value in it! Your work truly helps the hobby! (Now I enjoy your videos at the airport with your friends the most. Such great fun and good people). My wife and I travel a lot so I'm adding a trip out there to my bucket list. She's not in the hobby but she's sat through enough of your videos that she'll get along just fine :-)
Excellent explanation, very entertaining and easy to understand. Thank you, Sir!
I have an interview for an RF engineering role next week. This video was a great refresher for what I learnt at university. You have a great teaching style.
Huh, fumbled back to this video and seen my comment. Update - I got the job.
Thanks .... I've held my amateur ticket for years, I work in radio .... Enjoyed the lecture!
I just got my first function generator. It's just a little $100 thing based on an FPGA. But ever since getting it I've been overwhelmed with thoughts of all of the different experiments I can do with it. One such experiment I wanted to try is to transmit and receive radio signals. So video lectures about antennas and practical RF design are really useful in helping me to realize that goal. Since I have no experience with RF at all. Before I got my function gen, the highest frequencies I'd work with were
genius explanations, truly a great communicator. I watched the whole thing. I love the enthusiasm and humor.
Thank you for one of the best lectures i have ever seen.
The scientific inaccuracies as mentioned in the disclaimer at the start are very few actually. This video is a fairly correct explanation of antenna behaviour.
Thank you.... this is exactly what I wanted... to understand the antenna “why’s “
I've learned so much from this gentleman. It wouldn't have surprised me if he wasn't a teacher at some point in his career. What a goldmine of information. ♥
In addition to these great explanations, you seen like a really nice bloke. Thanks for the video.
That rings! By far the best lecture on antenna theory I have ever heard. Respect, Sir!
You're so AMPED up about radio :D Love this video, thank you very much!
I have waisted a lot of time to learn the maths behind this. This is the best way to learn. Thank you
This guy is awesome!
I enjoyed the video thoroughly!
Thank you for taking the time to explain this!
What a great explanation of antennas! I've just started with amateur radio and have built a couple of antenna's and this is the best explanation of how they work!
You are a wonderful teacher, sir! Thank you!
Thank you very much for this video. I have been looking for a video that explained antennas that started from the very beginning and did not assume antenna knowledge and this is the video that helped me understand. Your starting with a demonstration with the magnet and the multimeter helped tremendously for my understanding of what was happening between signals and antennas. Thank you very much!
Ahhhh....That just squeezed all my thoughts, questions and university courses into a 35 min vid
Yeah, Prof. Heisenberg is pretty awesome.
Really ? What a loss of university courses that was...
You make a very good instructor! When I was in school I would turn to TH-camrs like you if I did not understand something in class. I am studying to get my hame license. And you are doing a very good job of educating me!
Amazing teaching, such clarity. Thank you!
One of the better explanations of antennas I have ever come across.
Thank you de N3GAQ
WOW!!!!! THANK YOU, VERY MUCH, FOR THIS INCREDIBLY COMPREHENSIBLE EXPLANATION OF BASIC ANTENNA THEORY, AND OPERATION!!! AWESOME!!!!!!!
It all boils down to what you need. Direction, distance, latency (latency if you go through a third medium like satellite or other). If you detract the maths, basically all what I have learned in the uni... thank you for your great explanation. GREAT WORK of free study!
Absolutely fantastic! Thanks for taking the time to make this.
Just came across your video while looking at WiFi systems. Wish I'd had you as my Uni lecturer years ago, you explained it all so much clearer and quicker!!
Actually i watched the whole thing and i loved it.
You're an excellent teacher, fixed my attention on the subject, learnt a lot from it and boost it with comedy ( bing bing bing ) giving your audience great recall ! UNDERSTAND IT WELL, THANKS from your avid follower from the Philippines !
