An expression is derived for the radiation conductance of an axial slot on a dielectric coated metal cylinder, using the work of Wait in conjunction with Parseval's theorem in mode space. The condition for no axial surface waves to exist is stated, and computations for the radiation conductance are then made, for a Teflon dielectric coating of various thicknesses, none of which support axial surface waves. The computations reveal that the radiation conductance increases with both the coating thickness and frequency, for the range of parameters considered.
