Yes and I have to partially take back what I said; a balun CAN double
as a CM "choke" and a CM choke can double as a balun. If
one wishes to balance an unbalanced line with a CM choke, then the
impedance of the CM choke must match the source and the load, which
makes the CM choke a balun and no longer a choke :-)



Although this URL:

http://www.radioelectronicschool.net.../ocfdipole.pdf

deals with a Windom Antenna, his text on the design, construction,
function and implementation of baluns is well worth the read.
