Yes. But one end of the dipole may have the better conditions to

if it only moves in one direction as it would have
to in a monopole there is no wave only a simple field.

I am writing about a dipole with one end visible and the second
shielded.

In nature is always as you wrote. The both ands are always "visible".

Light is always directional. Radio waves can be omnidirectional.
Of course light is emitted by many dipoles. Radio waves by halve, one,
two
(circular polarity) or many (phase radar).

Astonishing understanding of the subject.

Light is not coherent. So dipole radiate for very short time.
Radio waves are coherent and can be from one source. It is easy to analyse
them.
Are they transversal?
