[TowerTalk] [Bulk] Re: BALUN revisited again

[Grant Saviers]

It is difficult to make a single choke for 40 to 6m but it is easy to 
put two in series on the feedline.  The K9YC tutorial has designs for 40 
to 10m and 6m.  I like using multiple type 43 or 31 small clamp ons for 
VHF, see the appendix for the recommendations.

Also, G3TXQ has a nice summary chart for chokes at
