The impedance of a short cylindrical dipole antenna in a hot uniaxial plasma is calculated. The hot‐plasma effects are found to be specially important for very low frequencies. For these frequencies the results of the cold‐ and hot‐plasma theories differ appreciably. As ω → 0 the cylindrical dipole is found to be capacitive rather than inductive as predicted by the cold‐plasma approximation.
