[TowerTalk] Multiband Radials

[Jamesnf at aol.com]

I noticed that Bencher/Butternut offers a set of elevated radials that offer 
multiband performance for 40-20-15-10.  That is, each radial is resonant on 
all four of the bands so only four elevated radials are needed instead of 
sixteen to cover 40-20-15-10. They're made from Belden 8230 twinlead.  I'd like to 
homebrew a set of these.  Has anyone seen instructions or an article on doing 
so I could refer to?
