We present a theoretical study of the potential produced by an antenna immersed in a cold magnetized plasma. This phenomenon is described in the literature as the {open_quote}{open_quote}resonance cone{close_quote}{close_quote} phenomenon. In this work, we take into account electron collisions with other particles (neutral or charged). We show that the domain{emdash}in terms of frequencies{emdash}where the resonance cone exists is drastically reduced for a collisional plasma. Furthermore, the resonance cone peak is shifted by collisions, so that the usual formula used to compute the electronic density is not quite exact. All the calculations are done with a finite magnetic field. {copyright} {ital 1996 The American Physical Society.}
