[Antennaware] Baluns and Cushcraft D40

[mike at hatzakis.net (Michael Hatzakis, Jr)]

I just bought a cushcraft D40, 40 meter rotatable dipole and want to try an
alternative to the 12 loops of coax.  Can I use an off-the-shelf balun used
for dipoles?  What is the feedpoint impedance of the dipole before the
balun, ie., should I use a 2:1 or 4:1 balun?  Ideas?
