Comments on "An exact formulation for the vector potential of a cylindrical antenna with uniformly distributed current and arbitrary radius" [with reply]

The paper written by Werner (see ibid, vol.41, no.8, p.1009-1018, 1993) relies on the technique and results that were developed by Overfelt (1987). At the time, I submitted a comment regarding that method (see. Gera, ibid. p.584, 1990). It seems that this comment applies here. Werner replies that the exact expressions for the generalised exponential integral are mathematically correct in the form that they appear in the paper, as demonstrated by the results shown. There are actually several equivalent forms which exist for these expansions.<>
