I made a video about this... Something I call "knowing your RF landscape."

Gil.

It is a vast subject... Let us know if you find anything ;-)
Probably a lot of antennas have been discovered by trial and error. The science is there to verify findings, but I don't think it can offer solutions. I believe a lot of informed intuition goes into designing an antenna...

Hi, never heard of it, which is surprising... Thanks.
Gil.

Awesome, thanks guys!
Gil.

Hello Ray :-)

It was very tempting... Rig from Italy... Still a bit heavy for trekking, but certainly a 9 on coolness ;-) I am considering building a Paraset... Historically very significant here...

Gil.

Awesome! Stick with it!
Gil.

Not very clear, but it does explain it somewhat. Very little electric field, but no doubt not zero, or there would be no RF produced, as far as I understand it. Interestingly mag loops can have a few thousand volts at the capacitor... That somewhat contradicts the statement.

Welcome aboard!

I once saw one one Ebay, untested, almost bought it, but it was about $500...

Hi, sure, if you will be the moderator...

Gil.

I'm all ears...
Gil.

I wish I knew...

The fact is that a radio wave is made of both an electric and a magnetic field at 90deg to each-other, since those are generated by the tank circuit, electric field by the capacitor and magnetic field by the inductor. A magnetic loop is said to "favor" the magnetic field... Whatever than means... I do not know how that happens, but it is an interesting question to investigate...

Gil.

Hello,

I need to reinstall the module and check the listing... Will do...

Gil.

Thanks!
Gil.

calculation correct ?

Hi, I don't know. I use an online Yagi calculator like this one: https://www.changpuak.ch/electronics/yagi_uda_antenna_DL6WU.php
