Amazing video and covered a lot of great points. One thing to remember is a lot of antennas used from aircraft to cars use a quarter wave antenna. The antenna is then grounded to the chassis or airframe which itself acts like a quarter wave, and in turn you get your half wave setup.

Catalin 🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

you and I are on the same page!! yes the pyramids were a interplanetary communication device that operated at a very low frequency. But also the great Pyramid of Egypt was a teletransportation device, ,, NOW Stone Henge and Gobekli Tape: they were power plants. , You will see chips on the upper parts of the stones as they were perfected to a operating frequency. The horizontal pillars were set to vibrate at a particular frequency magnetically, for many reasons, each horizontal rock had a purpose!! some were used to excite the seedlings in the ground, to expedite the growth, some were tuned into earths mag field and provided magnetic lift via the Earths "B" field . Check out Coral Castle Florida, ED used What I call a "B" field generator, His generator used "V" magnets to ensure max delivery of the "B" field Just like is being used at the black pyramid of Alaska. His generator used 25, V mag around and 5 deep to produce the "B" field into the earth and special stones. THE "B" field is the center of a magnet/ some like to refer to it as the neutron field. But the 'B" field is much much more !!! I wonder if the black pyramid of Alaska used magnetite as a skin for the pyramid that would explain many things!!! Tesla new about the free power that's available through the CENTER FIELD of a magnet AS you are well aware the rich boys didn't want it, It's been there all the time. When the government took down the horizontal stone at Coral Castle the entrance door stopped working. Funny thing they gave us the clue,, His horizontal rock was providing the magnetic energy to support the access door. AS you know magnetic energy is perpetual JUST GETTING started with all this. I don't need to brag about all my credential.!! I got into physics back in 1959 as a ham operator at 9 years old I would design and build my tube type radio's for Rec and xmit. I know what I'm talking about.. When they say all they had were copper tools OMG HOW STUPID!!! when you understand the properties of a inductive that being utilize to build the pyramids you would understand a copper tool was every bit of a power tool BIG TIME!!!!!!!!!!!!!!!!

[@davidbrayshaw3529]

Contrary to the information provided at the beginning of this presentation, closed circuit inductors most certainly do propagate radio frequency inputs and they are very capable receiving antennas also. This type of antenna is popular amongst "ham" radio enthusiasts and has proven effectiveness. All antenna designs are inductive devices, not just loops or coils. A dipole is also an inductor. What differentiates an antenna from other inductors such as an ignition coil used in a car is the frequency of the input signal. At low frequencies the electromagnetic wave surrounding an inductor will collapse back into the inductor as the polarity of the wave form reverses. A good example of this can be found in power transmission lines operating at 50-60hz. They do have an electromagnetic field surrounding them but with each cycle the field collapses and is absorbed by the transmission line. You can imagine the inefficiencies of transmitting power if this were not the case. The key factor in creating radio propagation is the frequency of the signal fed into the inductor. It is generally accepted that to effect radio propagation the signal fed into an inductor needs to be 100 khz. and above in free air. In order to understand radio propagation it is vital to understand that like charges repel each other. When a radio frequency signal is fed into an inductor an electromagnetic charge is created around the inductor. Because the frequency of the input is high the electromagnetic field cannot collapse back into the inductor before the next peak of like charge enters the inductor. Again, like charges repel. This forces the electromagnetic field surrounding the inductor to "snap off" and to be "pushed away from the inductor and thus we have effected radio propagation. What is a radio then? Good question. In the case of something like a radio station transmitter it is a device that converts audio frequency (80-20000 hz.) into a much higher frequency i.e. 106.7 mhz. and feeds that signal electrically into an inductor (antenna) which is then propagated as an electromagnetic signal. In the case of a radio receiver, it is a device that converts a high frequency electromagnetic wave down to frequencies in the audio range and with the use of an audio amplifier and speaker back into sound. I hope this has been help to anyone trying to grasp the basics of radio like I did.

[@dwilliams2068]

Drop the 100 khz comment. What frequencies do submarines use when under water?

[@davidbrayshaw3529]

@@dwilliams2068 ,Submarines use very low frequencies for radio. Audio frequency transmissions are possible underwater. Low frequencies are employed underwater as signal attenuation increases with frequency in this environment. Note that in regards to my assertion that radio propagation starts to occur at 100 khz I do state "in free air". This is perhaps a generalisation, it is possible to detect frequencies below this level but in the context of both propagation and modulation the practical limits imposed on these lower frequencies makes them a fairly ineffective carrier of data.

[@dwilliams2068]

@@davidbrayshaw3529 Yes I know. Among other assignments in the navy I was ASW Officer on a destroyer and had many interactions with submarines, fortunately our own subs. You are probably familiar with the UQC.

[@dwilliams2068]

@@davidbrayshaw3529 I really don't know. I left the navy many years ago, but there is something that might interest you. The UQC on our ship was built by Bendix Pacific. As I was being relieved from active duty in San Diego there was a flyer on the table from Bendix Pacific in North Hollywood. Having had a long experience in electronics and a degree in Engineering Physics, I decided to visit Bendix and was hired on the spot. I was given a desk and a budget to buy books on transistors and dit early work on solid state telemetry systems. I worked in telemetry and later moved to San Diego to work on the Atlas missile, followed by many years in aerospace and commercial projects. Returning yo my time on the destroyer, I was also Electronics Officer. We had a shipyard overhaul and our radios were all converted from VHF to UHF, all but the TBS on the bridge. Many times we could see a ship but not be able to talk to them on the radio systems, while the captain, using the TBS on the bridge, could. It caused me much grief. Only when I started working on missile tracking systems did I learn that the UHF failure was destructive multipath.

[@dwilliams2068]

@@davidbrayshaw3529 Too long ago to know. As I left active duty I saw a brochure from Bendis Pacific who had made our UQC. I thought it was interesting so I went there and was hired on the spot, based on my experience and degree in Engineering Physics. I was given a desk and a budget to buy books on transistors. Within a year I had developed the first solid state telemetry components and had a patent on one circuit. Returning to the ship, I was also electronics officer. We had a shipyard overhaul that replaced all our radio systems, except for the TBS on the bridge, with UHF systems. Sometimes we could see a ship but couldn't contact them on UHF but the captain could reach them with the VHF TBS. It caused me a lot of grief. Only when I moved back to San Diego to work on Atlas missile tracking did I realize that the UHF systems were affected by destructive multipath reflection from the ocean.

I have a question. In the animation where the antenna creates the signal, you can see that he signal spreads out as it propagates. During the animation where the antenna receives the signal, you just played the first animation in reverse, but wouldn't the geometry of the incoming signal look completely different (it wouldn't magically be drawn towards a point)?? Thanks!

Good point. signals are not focused to receiver antenna like showed in the animation. Isotropic antenna waves propagate all directions equally, so the gain of the receiver antenna is inversely proportional to square of the distance.

The animation of the field lines for the induction case (from 0:35) is *wrong*. Field lines do not get squashed or deformed into increasingly eccentric elliptical shapes. They maintain the same shape, but - following Faraday representation - get rarer and rarer as the field strength diminish, then they disappear when the field goes to zero and reappear oriented in the opposite way when the polarity shifts. Then they get denser until they reach the maximum and the cycle repeats itself. You might want to correct that in your next video on the kink generation. Also, as others have noticed, you cannot just reverse the field to show how the antenna works as a receiver. You should place the receiving dipole outside the origin of the emitting dipole field (still propagating forward) and then make the electrons inside react to the portion of the field intercepted by the receiving antenna. This will also illustrate why so little power is received: most of the emitted energy goes in all the other directions. The animation of the dipole field of the transmitting antenna is very nice to see, I have to say.

Thanks is there an animation or a textbook that shows this more accurately?

[@samwinchester7844]

Thanks for the great video. I studied electronics in undergrad but never learned what's shown here. Excellent video!!!

[@ninodroid2382]

Great video and clear explanation👍 Wish my professor could explain like this.

I live in Karachi Pakistan I like your comments thanks

[@paulromsky9527]

Great video. At 6:35 you can see the "Near Field" effects of the antenna (about 1 wave length) as the magnetic wave loops start to compress and break into linear fields. Another thing antennas do is "Impedance Match" the transmistter/receiver (50 Ohms in transceiving antennas) to the impedance of air. There is a lot of electromechanical science in antennas. Also, electromagnetic waves do some non-intuive things at higher frequencies. Frequency ranges are divided up into groups called "Bands". For example the K Band is known for its interaction with water vapor in the air. The frequency at the center of the K Band is the resonate frequency of water. Your microwave oven works off a harmonic of this in a lower frequency band. Because water molecules in the air absorb enery the most at these frequencies, they "Attenuate" or reduce the strength of the waves for long distance use. Other gases and molecules in the air also effect electromagnetic waves to varying degrees at various frequencies.

Very nicely and deeply explanation, great work! 🙂

I can design my own antenna after this video.

[@leviaralikatti5634]

I am addicted to ur videos it is very interesting and knowledgeable

[@nikan4now]

Could someone answer my question please? So does that mean in 3D, each electric wave is a doughnut-like shell (surface) that keeps growing in size as it propogates? Or is each wave a doughnut-like volume (with non-zero field values inside it) as it travels?

We live in a 100% magnetic universe..... it's that simple!! The center of a magnet is by far the most powerful part!!! that's where you will find anti gravity and most everything else. STUPID HUMANS!! We went backwards in the Iron age!! the center of a magnet is where we belong after all that's what we are all configured with..FACT! Please review the works at "CORAL CASTLE, Florida. (KZbin), He would "VIBRATE" ,, not oscillate the granite at a resonant frequency to the type stone he was working with. Granit has allot of magnetic properties given it's make up... You just need to vibrate at the correct freq. and it will become workable. Keep in mind we are talking about vibrating only the "B" field of a magnet into the rock!!! You will note at Coral Castle he also had a horizontal stone , similar to Stone Henge... All his magnetic generators were in the repel mode to maximize the "B" field.. SIMILAR TO THOSE Shown ON THE PYRAMIDS OF EGYPT.. FACT!!, THINK about it THAT'S exactly why they used copper tools!!!! You must use copper tools and any iron would totally dispute the field. Quantum Math is total B.S. E=MC2 is also total BS... E=MD. (Magnetic density). Thanks Vincenzo.. Please use your brain!! If your professor gives you any flack, have him explain the speed of magnetism. It's instantaneous. That's how they used the pyramids as transportation devices, inter Galaxy type transportation that's exactly why they were 8 sides to create a perfect hologram from earths magnetic field that could be used to connect interglacially
