Based upon a boundary‐value formulation, a new approximate expression is derived for the total axial current on an infinite antenna immersed in an unbounded, cold, collisional magnetoplasma with a dc magnetic field oriented parallel to the antenna. Numerical results are presented for the current distributions over plasma parameters corresponding to each of the eight regions of the Clemmow‐Mullaly‐Allis diagram and for different values of the collision frequency. These results show that the propagation constant of the current wave on the antenna is very nearly equal to k 0 ( K ⊥ ) ½
