Caution on this. See JUN 2015 - QST (PG. 30) "Don't Blow Up Your Balun"
by Dean Straw, N6BV

Dean's work clearly shows why it simply is not practical to choke a 
non-resonant antenna. And, because receive noise is such a major issue 
for most of us, it's why I don't recommend antennas like this. The 
random wire and off-center fed wires were great ideas for 30 years ago, 
but terrible ideas today.

Fan dipoles are a FAR better choice.
