Obviously, i like the cost of building an ugly balun, but will it work
as good as the 1:1 dx engineering balun? Thanks in advance.


# Here's some information: http://www.karinya.net/g3txq/chokes/

# As you can see, there are none of the air-core baluns that work very well
80m-10m because they are narrow-banded. Note that 25 turns is not enough
turns for 80m and too many turns for 10m. Compare the bandwidth of the
ferrite toroid baluns to the # bandwidth of the air-core baluns. (We might
define that bandwidth as any color except red, i.e. any frequency where the
choking impedance is greater than 1K ohms.)

Nice link.
