HAM RADIO - Magnetic Loop Antenna Coupling Loop & Remote Tuning Update

I've made more than a few MLAs, but none looked nearly as nice as what you have here. I've probably made less than 10 contacts (no dx) with any of them in total. All qsos were ft8/4, except for one cw and that got me a 22 sig report. Still it is a lot of fun to build and learn from building an MLA. Mine is currently stashed behind a cabinet. I used 1/2 inch Heliax for the main loop and have experimented with many different feed coils. Hopefully I will come across a vacuum tube capacitor someday and I will give it another try. Thanks for sharing your experience.

Good job Almir. Now you got a little Flamethrower to make your Signal skipping across the Pond. I can't await to finally make the 1st Contact with you on the Bands. Have a good new Week & 73 de Uncle Günter 💯🙏🙋‍♂

Boa! Essa antena eh magica. Obrigado.

A loop of 1 meter is about optimum for the 20 through 10 meter bands you are operating at this time. For lower frequencies such as 80m the loop would need to be a wider diameter. One thing to avoid when designing loops is to choose a diameter that avoids lumped current constants, which occurs typically when the loop diameter is too large for the frequency used. It's a fine balance. Larger is not always better when it comes to MLA's. Great work. I love your project.

VE3DAL, Thanks for the demo of your new Loop. Just wondering where you found the variable capacitor?... Never mind, I found it on an earlier posting.. Cheers!

Brilliant video and you are a very clever person. I just ordered the qdx for qrp ft8 80-20m, so I really do hope to hear you one day. I find ferrite clamps work as well as a 1 to 1 balun, but easier to connect. 73 zl3xdj

this is cool where u get the butterfly cap from?
