Hu Uwe, the loop you quote is still quite small but it should radiate. I produced a Excel speadsheet that compares a loop with a T at the address below...I think the files is Loopcalc.xls but a click on this page should download it to you.

There are details for tuning and matching a loop entirly with switched capacitors somewhere. Rik, ON4YDs site may be the best starting place.

Subject: LF: Tee- Ant. vs Loop ?

To all ,

I would like to built a Tx antenne but with linited space I need at least a bulky 4 mh and variometer.

So I wonder if I could not use a loop antenna ( 20x 10m ) ? So I would not need such big coils ?

( high voltage vs. high current )
