It is almost surreal to see a young person interrested in these sort of things. 😨

nice job man. loop antennas are so cool.

Very cool! Love that build. Great job.

Built one a few years ago. It’s larger than your but works the same way. Very selective antenna and quite directive as well. Yours is nicer looking. Keep at it, exploration is what the hobby’s about. KE5TJ.

The best video i watched in a while! How you setup the Sdr with a loop antenna is awesome! Im bot sure if you can replicate the same experiment with the HF bands instead of MW!

Great video.

your inner loop is not purely in resonance with outer loop. You must add another gang capacitor with smaller loop antenna in parallel with loop and the BNC connector. First tune your SDR to a known nearest AM station. Then tune your cap of mini loop to get the signal of that station stronger. Then tune outer loop cap to make it further strong. Then again tune smaller loop antenna slightly if you get it further strong. That will be the sweet spot and both the loops will be in resonance on that very freq. Secondly try to make smaller loop antenna with thick power cable and check its inductance to be close to 204uH. Please do write about the result. Thanks.

Nice demonstration

Nice illustration.

do you know if bunching up the wires all in the same "bunch" would affect the antenna negatively? i meant to say to have the enamel wire together, like in a transformer, instead of separated side by side?

WOW ....amazing

Great!

how about a loop for MW RADIO?

What is the tuning range of ur capacitor?

Does the spacing between the wires matter?

One of the best videos about AM loop antennas. I got a question: since it is very difficult to find a variable capacitor, I thought if it is possible to make such a variable capacitor out of foil pipes (the ones we use for cooking in the oven). I even made one, with two pipes of different diameter (they fit in each other perfectly), connected a loop antenna and started experimenting with my Panasonic radio, sliding the smaller pipe in an out. I had checked the capacitance of my capacitor, it varied btw 100 and 700 pf. I checked all the medium wave frequencies but my radio reacted when only I set it to 1240 Khz. there was no station but the signal was amplified so much that the radio wrote "tuned". I don't know why it happened and why my jumbo capacitor didn't work for other medium wave frequencies.

Kudos to you Thomas, for using a proper coupling loop design (for the 50 ohm output) that follows sound practice, such as the approx. 1/5th size of the main loop-- see this informative page on loops: webclass.org/k5ijb/antennas/Small-magnetic-loop-coupling-loops.htm . Also, the sharp peaking is partially due to your wise choice of the ceramic air-variable cap; These are usually higher "Q" than lesser quality capacitors. They are the choice of serious crystal radio builders. By the way, are you familiar with Ferrite Sleeve Loops? I have built a few of these for chasing overseas medium wave (AM band) distant signals. Here's a link to one I constructed: swling.com/blog/2017/01/a-new-approach-to-fsl-antenna-construction/ Keep up the good work with your videos. 73, Guy

Hi. I have the SDRplay RSP2 Pro. I desparately need a wideband discone antenna for indoor use. Have you heard of such thing?

I ahve made 3 projects of MW antrennas . The australian loop and 1x1m square x 9 turns of wire , another from a vegetables basket and the word famous An200 tecsun that has about 20 db gain in most of the band but i stoped with that . the remain are not easy to handle Only untuned antennas can work with SDRs!!
