usually, it's connected to something else that is also dirty (rope) or a
conductor (e.g. wire) or something.. In the case of the
dipole/balun/coax, then the leakage path is on the surface of the balun
to the shield.
It doesn't take much to have a leakage path that will bleed off static.
If it gets below freezing, though, or you're out in the desert where
it's very dry, then you're more likely to need something extra. (dry
blowing snow or dust can deposit an amazing amount of charge pretty
quickly... lots of documented stories back in the telegraph days of
steady arcs from the lines to ground)
