Any type of balun necessary with this?
YES! Lots of work by Rudy Severns, N6LF says so. His extensive work on
radial systems is well worth the time to dig through it. You can see
photos of what I did on two 160M verticals with elevated radials in the
160M "small lot" tutorial that's on my website. The white coax shown is
the plenum version of Commscope 3227 (2427, I think) that has the
advantage of smaller o.d. by virtue of the plenum outer jacket, thus
allows more turns through the same diameter core. See the Cookbook
chapter of my RFI tutorial for choke recommendations.
Your proposed antenna sounds like a winner, but you really need to study
Rudy's latest piece, published in QEX this summer, and downloadable from
his website. Google to find it.
