Hi, Chuck.
I have a question about your feedline:

I know that coax can be looped around 5 times to
create
a balun near the dipole feedpoint. Can twisted pair
be looped around to create a balun also? Also, what
was
the distance between the twists? I'm interested in
making one to feed a dipole for my KX1 field kit :)
How can you measure that a balun is being effective?
Thanks,
Martin.
