I'm looking for some details on the dimensions and design of the Barker and
Williamson "folded dipoles", for the purposes of building an accurate NEC
model.
From some casual web searching (on TT, among other places), it looks like
these things are basically a folded dipole with a resistor in the middle of
the fold.
I'm looking for things like detailed dimensions (how far apart are the two
wires?)
What's in the "coax to antenna transition"? Is it a balun? Or, is it just
two wires?
What's in the "magic box" at the top of the antenna (a resistor? a tuning
network?)... the photo on the B&W website shows a metal strap between the
magic box and the coax, but it's not clear if that's an actual electrical
connection (if so, to what)
I'd also be interested in any measured performance data (who knows.. the
gov't uses them, maybe someone actually tested one on an antenna range
somewhere?)
Thanks, all...
Jim, W6RMK
