YES This is a very educational experience!!

I think this video explains perfectly why I love having electronics as my hobby. There's so much I don't know, so much to learn. I occupies my mind. I run my own small engineering company as a day job but learning electronics from people like Mr Carlson is becoming a bit of a 'passion'. Every small breakthrough is a massive high for me. I have a heap of vintage valve radios I've been wanting to restore and this channel has taught me so much about the proper technique to use.

Paul, you do have one hell of a setup there. Great video as always. I appreciate the time you put in your quality videos, a pleasure to watch. Best regards from germany, my friend.

Can’t wait to see more with the 3-6-9 antenna. Maybe baluns and antenna tuners.

The theory behind WARP drive engines is to compress the 'space' in front of the spacecraft and 'expand' it at the back of the spacecraft. -- Though no one has been able to figure out how to do it. Thus like evolution of the species, it remains an unproven 'theory'. It is unlikely that civilization will survive long enough to discover the answer. All we have discovered is 101 ways to destroy this world we live on - Newer methods of ecological destruction are being invented.

So awesome that Mr. C uses classic vintage and custom built equipment.

Paul, I am so envious of you! Well done, you earned the bragging rights!

pretty soon all the radio stations in a 100 mile radius are going to wonder why their breakers keep tripping when you short those antenna leads ;P

I wish that you had a SDR on that 3-6-9 antenna that we could listen to your SDR online that would be cool.

Well, there you go, it a great example of inductive coupling.

Nice, efficient enough to light up leds just from RF in the air like a wireless power setup. I guess a downside to that it's also very efficient at picking up 50kV spikes from lightning strikes even at 10-20 miles away. I don't think the leds would like that. Doesn't receviers have peak input signal limits of just a few V before something bad happens?

Fascinating demonstration, and very well explained!

Back around 1958-'59, Popular Electonics (or maybe Electronics Illustrated) had a do-it-yourself project for an entirely antenna-powered receiver/amplifier. Tuned to a strong local station, it generated enough voltage to power a transistor amplifier. Then a second tuned circuit could select a different station and be heard louder thru the amplifier.

Excellent as always!

Mr Carlson, have you considered ground rod earth loops by having four rods as you described. Also, regarding the distance of the rods apart giving rise to bigger earth loops but better overall impedance to earth. Also, the resistivity of frozen soil compared to warmer soil for example....? I guess it's worth having these new issues in comparison to a noisy grid tied earthing system but would love to hear your input or perhaps experiments.

Phenomenal. Thank you.

Thanks Paul. that's an awesome experiment for the antenna efficiency. the ground magic is under considered in electricity/electronics schools, at least in my humble experience.

Induction... it's amazing stuff. How many LEDs could be lit up this way? The antenna receives RF from remote radiostations, obviously, which is what powers the LEDs. I am curious - would the antenna be 'good enough' to power LEDs from just cosmic background radiation (assuming no radio stations) and/or anything else it'll pick up? I am asking because it reminds me a bit of Tesla's experiments with a elevated plate being charged up and periodically discharged into a capacitor, gathering supposedly minute quantities of energy. I think later in his life, on July 10, 1932 Nikola Tesla stated: "I have harnessed the cosmic rays and caused them to operate a motive device." That may be a different experiment, but interesting too. All this is very interesting stuff. Thanks for sharing, mr. Carlson! Much appreciated!

I guess it depends how far away a thunderstorm is.... ? In fair weather it can be 100-300Volt per meter (height), and near a thunderstorm it will be in the thousands of V/m, strongly peaking when striking. I don't think it is all rf, but I could be wrong.

Nice WWVC Rx. Nice Variable RF coupling transformer demo!

I did a similar experiment on my 160 meter Inverted-L antenna. I live in the middle of three 5KW AM broadcast stations. Each are about 2.5 miles from me. Connecting a full wave diode bridge across the antenna terminals I read 36 volts. Shorted I get 8 ma. Lights an LED very bright! Connecting a frequency selective level meter I measure +10 DBm on two of the three and a little less on the third.

I cannot wait for ur new antenna vids!

😲 Very neat stuff! Thanks!

Nice box... At some point it would be fun to add a 10MHz reference to my lab, but given our business focus on analog audio, its not really a high priority to have ultra precise frequency measurement.

Totally awesome!

I have a strange feeling , this is not the sort of guy that repairs iPhones at the mall

Nice demo!! I've known this could be done for some time.

Thanks for the demonstrations. The powering of the seven LED's from the antenna was the most interesting. The estimated minimum power is 14 mW based on 1 mA for the brightness and 2 V for green LED's.

Yes, oddly enough, we rarely have lightning here, but when I was at the top of the ladder working on the antenna, there were some flashes far off and distant thunder, I could draw arcs from the coax F connector to the mast pipe. This was before the ground rods were connected. I'm very glad I didn't touch the mast and F connector at the same time at the top of that ladder! What are the chances of all this happening at the same time? I should go buy a lotto ticket.

@@MrCarlsonsLab When I built my first receiver, a transistor super-regenerative short wave radio kit, it needed an antenna. I used 30 feet of magnet wire strung on small hooks under the eaves of the roof across the front of my home. Since I lived in tornado alley, severe thunderstorms were fairly common. The first time I saw a storm approaching, I disconnected the antenna from the radio so I could attach it to the air duct which I used for a ground. Before I could attach it to the duct, there was a flash of lightning more than a mile away, which I saw and felt at the same time. This demonstrated to me that you don't need a direct lightning strike to generate some impressive voltage spikes in a 30 foot wire antenna. Static / corona is another thing that can build up on elevated metal objects during storms or from falling snow, as you have shown in another video.

Very Tesla-esque as many other people have mentioned. Paul, I'm interested in how you calculated the three antenna lengths and how the shorter ones inductively couple to their longer extensions. Is there a coil between the two lengths or is it just an insulator?

You have demonstrated that the antenna extracts a nice chunk of energy from the radio waves it encounters. The method of multibanding is very clever, too. But the "goodness" of an HF antenna is not determined by raw signal strength, because due to the relatively greater amplitude of atmospheric noise compared with the internal noise generated by the receiver, it's possible to simply amplify the output of an inefficient antenna as much as is needed. This is why small loops with preamplifiers can be good receiving antennas. The real test of a receiving antenna is its ability to provide a high signal-to-noise ratio. Given that we are not talking about highly directional antennas, that comes down to rejection of local manmade noise. I believe that since the outer shield of your coax is not decoupled in any way from the common lead of the antenna, it will provide a path for local noise from your noisy lab back up into the antenna. A worthwhile experiment would be to connect a ferrite choke "balun" (not really a balun, but that's what most hams call them) at the feedpoint and see if noise pickup diminishes.

Hi Paul, excellent video as always thank you. I will now go and tweak my substandard antenna 🙄🙂

Interesting,... listening to the antenna tech.

The magic of RF.

Is this a traveling wave antenna? I've not seen the element coupling like this before. For TW antennas, they're terminated into a 50 ohm resistance, but you're not doing that. Is the inductive coupling of the isolated wire elements functioning as a type of matching stub?

A few years ago Paul demonstrated a transmitter he built and how energy from that could be monitored (seen and measured) on another receiving antenna as such. That's what purposed my subscribing to this channel. Notwithstanding, I'd like to see Tesla's demonstration of wireless electrical transmission duplicated, specifically with his "hair pin" circuit, and how he achieved lighting "carbon button" single wire lamps he patented. Though I recommended it previously, I again reference "Secrets of the Cold War Technology "as a starting point for the curious minded. (Note please: The actual source for that work see Dollard.)

Super !

You are amazing. I started to love inductors by the way. I design wireless leds.

Magicians Show. I expected a deck of cards any time.

In my Sony STR-7045, underneath the tuning capacitor and its clear plastic cage there is some circuitry that you can access from underneath the unit. Just putting your hand in that area without any physical touching changes the tuning and thus what the radio receives and amplifies. It's wild!

Cool to see around 15:35, a little bit of current sneaks through the LEDs with just your hand on the other side! I never considered how much power you could extract from just stray RF, I wonder how much you could get if you lived nextdoor to a transmitter.

This new antenna would be great for demonstrations with a simple crystal set. You could demo variable inductive coupling methods, achieving selectivity, etc., etc. I've always found crystal sets to be loads of fun and very instructive.
