Hi Jim,
Everything has a capacitance to somewhere. Even Mother Earth has a
capacitance. You can select what reference point you like, Moon, Sun, Pluto. I
never really grasped it myself when I took my classes in physics.
Anyhow, there is a distributed capacitance along the dipole wires that get,
what's called, end-effect. That's why you don't cut the dipole to exactly
1/2 wave length but a little shorter, most around 95%.
We all, I hope, know that the voltage is highest at the tips of the dipole
(or 1/4 wave verticals for that matter). That's why you put a good
insulator at the dipole ends, not just a non-conducting cord (what might catch
fire
a rainy day).
Just my dime to the conversation,

## BTW, when you mentioned dipoles etc, having all their voltage at the
tips,as
a result of capacitance, capacitance between what and what ? Is it
capacitance
between the tips, like in an arc ? I cant see it being C to ground
below. What
if the dipole is in outer space ?
