Thanks Stuart.
That's interesting, as I've also seen another type of loop where there are 2
loops one above the other constructed with a single wire. In other words, a
double loop.
The spacing is about 8 to 12 inches loop to loop.
I have worked a guy using one of these on 40m, and he thought it was good.
It's fed with 450 ohm line and a balanced tuner.
I'm not convinced that it would really be any better than a single loop, and
his signal was not noticeably stronger than other guys using single loops.
Not really a valid test I know.
Did you ever hook feeder to the metal edging around the club building?
Congrats on the KH6 @ 5w, very good!.. wish I had the room for a big loop or
rhombic here.
Cheers.
Paul MW0CDO.
