So Arno, if you know this delete and you're making "plenty of contacts"
so you may but just in case. The Alexloop is a resonant transformer.
At it's resonant frequency, the coupling from the coax to the big loop
is huge. Off its resonant frequency, it is nil. If you have an ATU in
your radio, you should bypass it and tune the loop to 1:1 or as low as
you can get it. Some folks have had disappointing results with the
loop, and in all the cases I worked with them on, they were
approximating resonance with the knob and then letting the ATU match it.
Good luck

So, when a used AL came up on Yahoo, I grabbed it and now, reading your
comparison, like it even more, having had the hunch that the BP will be a
bit more like my wires in the tree, as far as setup time is concerned. Of
course, an A/B/C/D comparison between the four would be better than
guessing, but I am making plenty of contacts with the AL.
