hey there.
I've come across an interesting idea.
one of the radio clubs over here sells antennas in kit form. one of 
these antennas uses a 12:1 unun to enable one to have a relatively low 
VSWR across most of the hf band without the aid of a tuner. incidentally 
this includes, vks737 frequencies, cb and marine frequencies and a 
couple of others, as well as all the hf ham bands. I didn't mension 160 
meters as that's classed as MF.
anyway, have any of you come across any good unun designs? if so, I'd 
love to hear about them.
the one I'm looking at at the moment utilises two pieces of copper 
tubing, 6 toroids, and a secondary choke wound through the copper tubing.
thanks in advance.
