With the coil in series with its internal resitance, the phase angle
of the current will be the same throughout all components in the
circuit. Of course with parallel components, the vector sums of the
current though each component must follow kirchoff's law. In parallel

Then you are doing a lumped element approximation.

It is probably adequate for analysis of a short loading coil.

That is probably not a suitable method to analyse a helically loaded
monopole (where the monopole consists of nothing but a helix).
