Coaxial cable involves two conductors, the inner pin and the outer grounded shield. If these modes are directly radiated to the space from the waveguides output, a doughnut-shaped radiation pattern will be produced, with a clear absence of signal in the axis (bore-sight) due to the fact that the transverse electric field is null in the axis (undesirable conical radiation pattern).
