😔

I just found your father's videos. I'm sorry to hear he is no longer with us. I am grateful your children will get to know some of his works as well as grateful for the easy to understand explanation of antenna operation.

Is he no more on earth? This man so lovely!

RIP Don, thanks for such a simple explanation.

He passed away ..?

When did he pay away

F

He passed on? Oh dear! Well, he has made his own contribution to life.

Really? Very sorry to hear of his passing.

He is alive

@@juantello2160 no he died. Read description

He died?

+Jonathan Slaven Thanks Jonathan, we appreciate your comment.

The dislikes could be because of the EXTREMLY annoying and useless background noise/"music"

Slaven Man's Gym put on a shirt, Mister gay.

Divide the total dislikes by the likes and you will realize it's insignificant

Thanks for watching William!

I wanted to ask a question... I am facing network issues inside my house so, can I use a yagi antenna for outdoors to receive the signal from the base station and omni antenna inside the room without using a repeater to boost my signal strength?

I know your comment was 4 years ago (to me here and now) but there are so many things this explanation just avoids. How do the currents in each wire 'cancel each other out'? A basic questions that needed explanation. Why did one wire have current flowing in one direction, and the other wire current in the opposite direction? How is current flowing when there's no traditional electrical path back to ground? (again, vital to explain for someone who searched this video up for an explanation on fundamentals) What made the high voltage point? How does it just 'meet up' at the point before expanding outwards? I'm sure I'm going to get downvoted to oblivion because people love putting sentiment before logic but this is a very poor video.

We're glad you enjoyed the video!

I absolutely love building antennas. I've been doing it since I was a kid. For some people what you can't see but can understand in other ways is absolutely exhilerating. I woke up the other day frustrated that a commercial antenna I bought didn't work so I built a type of antenna called a folded fan dipole in 30minutes with a piece of wood, a small piece of copper wire, and some speaker cord! ANd guess what? It worked amazing!

He died

It would be nice if he could do that but he is no longer with us bro 😩.

+William Newman William, You're welcome. Thanks for watching.

Primary winding ? Secondary winding ? If you are a ham operator you must have remembered the answers cus you don't know RF. You are describing how a transformer works not an antenna. If you are going to make a good antenna you want it to be resonant. If you know what that means. I don't know what you were tought but you are wrong.

swatter 521. I still support what I said however in that a signal fed to an inductor primary (conductive wire) creates a magnetic field which which is then coupled to a secondary inductor to convert the magnetic field back to electrical energy as in any untuned transformer. One can also make an RF transformer such as with an i.f. transformer using the very same magnetic coupling from primary to secondary. Now make the i.f. transformer perhaps with only turn such as in a resonant or even a nonresonant loop and place it near enough to another receiving loop and there will be at least some of the energy magnetically coupled there. Make them both resonant to a given frequency and the coupling becomes much more efficient of course. Those could rightfully be called antennas. Even the nonresonant loops could be consixered antennas only with far less efficiency. From there it's simply substituting any other antenna design, usually resonant, and get energy coupled between them. So, we have in the first place a transformer magnetically coupling between conductive windings (wire), and antennas in the second place which couple energy magnetically, and thus an a legitimate analogy being drawn in that any of tbese systems couple energy. Perhaps now you understand my analogy. Whether you understand it or not, or agree or not, I still stand behind it.

joe woodchuck if you been working with electronics all your life i don't know what to say but im sorry you are wrong. I been also working with electronics all my life plus i have 2 degrees a master in electrical engineering and a bachelor science in electronics. Plus i have been playing with RF since i was a kid. I hold a extra class ham ticket. A army MARS licence and a GMRS licence. Plus i own and climb commercial towers. I went to ANDREW for terrestrial microwave school, coax school, and, connector school. So i have many years of radio experience. You can not induce a magnetic field with rf. You are confused . To induce a field you need Ac power. That is why we don't use dc for housing and every day power. You cant step up dc with a transformer. That is why we went with tesla instead of Edison. Rf and ac use difrent types of transformers. For different reasons. An antenna has no transformer. I have made every type of antenna possible and a few designs of my own. Not a single one had a coil driving a coil doesn't work that way. A coil on an antenna ad's inductance to electricly shorten the physical legenth. Nothing more. It's a trap. Cb or 10 meters 102 to 108 inches is a quarter wave. No coil. 2 meters 15 inches is a quarter wave. No coil. 70 cm 5-6 in a quarter wave. No coil. The antennas with a coil are all in series. So when you send rf into you so called transformer how do you hook up a radio? Run the center lead of 50 ohm coax to one side of the coil and hook the other to ground? If you do that you will blow up the radio cus the coil is a dead short. Put a ohm meter on your coil transformer it will show a closed circut. You hook up a nice icom to that and you will be sending it back to icom to put a new p a in it. Don't put a amp on it. What is your SWR with that set up ? How much resistance is in there ? What is the impedance on that hope it is 50 ohms. It's not gonna be i guarantee. Tell me how that talks. Hope you don't need to go down to 80 meters gonna be some big transformers. Lol 😆 the thery you are imagining is all wrong for rf. What you are explaining is for AC power except all the resonant stuff. Transformers use turn ratio to turn ratio like 11 turns primary winding 65 turns secondary winding and the gauge of wire ratio between the two around a steel core. Just because you been into electronics all your life doesn't mean you are right. Whare is the coils on a yagi ?

swatter 521. With all your credentials you didn't even understand what I said. For one, where did I mention dc? For another, what is it you've been missing all through your career that antennas radiate magnetic fields that result from the application of alternating current? The field alternates too which you somehow turned around to your own interpretation. Once again, one antenna radiates a magnetic field (alternating of course) and another receives the field and converts it back to AC at the same frequency of the radiating antenna. That ac signal electrical signal feeds the first rf amplifier stage from which it goes on for further processing according to what modulation mode is being used. If it isn't a magnetic principle between the antennas, then what is it? And yeah, I know about E fields, but those are considered in communications to be near field.

Oh, and I never said that antennas needed or should be coils. If you had bothered to absorb the full process of explanation and contextual meaning of what I said, you'd have realized that. You're very good at changing other people's intentions and what they are trying to convey. May I once AGAIN say that I never intended for a magnetic field be interpreted as static for antennas as in dc, but rather an alternating field. That point should have been obvious.

Thanks for your comment, glad you enjoyed!
