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.
