Actually I was a little surprised with the outcome of this experiment. I
use a coupling loop now which is between 1/3 and 1/4 size of the main
loop. SWR on 60 till 15m now is below 1:1.6. I think that is a very good
result. I consider my magnetic loop ready to go now. Now next
thing.....testing on air.
============================
You might achieve SWR 1:1 by slightly rotating the coupling loop inside
the main loop.
