[Elecraft] Portable antnennas

[Fred Jensen]

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
