[Towertalk] Choke Balun on RG-59 Coax?

[wd3q@erols.com (Eric Rosenberg)]

I'm going to feed my new 80/160 EWE's with RG-59 (have LOTS of
it!) and want to put choke baluns at the feedpoint. 

I have the Wireman kits and QST article, but would rather put
the ferrites directly on the feedline. 

The question:  how many beads do I need (considering that RG-59
isn't the same as the RG-303 that is called for in the article),
and what size.

Thanks in advance,
