You can't go wrong with good insulators at the ends of a dipole or the
top of a hanging monopole. Long ceramics or glass, dogbones, rope a
couple or more in series, help minimize loss when the support rope is
wet. Take a look at long guy insulators on 50 KW AM stations--some
have corona rings--that's wild overkill for ham but the concept is
valid: more insulation, less loss. If the dipole is one lambda then
it's voltage fed so the center insulator should be more than a single
dinky dogbone, _in my opinion_.
It might be interesting to run a neon bulb along a dipole to see if it
dims along the way. It has to be made sufficiently insensitive I
think.
