Howdy Y'all:
Chushcraft says that the Ringo Ranger II is the latest design featuring
three 5/8 wave radiating elements and an adjustable 1/8 wave phasing stub.
My question is why a 1/8 phasing stub? Should it be more like 3/8 or
somthing, and why only
one phasing stub, should there not be 2? And is the outside of the coax that
comes from the ground plane a radiating
element? This antenna has me scratching my head, any ideas?

Sounds like marketing in action; I'd call it a two element colinear
with a decoupling section at the bottom. Just for giggles, what gain
does Witchcraft claim?
Howard
Crunchcraft shows 7 dBi gain-- and b.t.w., the 1/8 wave- DOUBLE it (it is a HAIRPIN)
, wave has to travel 2 X the length (plus the extra 1-1/2 inch width)! Actually 1/4
wave LONG phaseing (for want of a better word) Section. This between 2 aprox.5/8
wavelength verticles Howard is correct!. Jim NN7K
