Luminous Blue Variable stars (LBVs) are massive and unstable post-MS stars undergoing different phases of instability, characterized either by photometric and spectroscopic variability or by mass-loss episodes. As a consequence of the mass-loss phenomenon, LBVs show circumstellar ejection nebulae, traced by dust and/or gas emission. A systematic study of a sample of LBVs, based on the comparison between radio and IR observations, is ongoing. The aim of this study is deriving the mass-loss properties for a better understanding of the LBV phenomenon in the wider context of massive star evolution. Among the most interesting aspects of this study is the gas and dust distribution in the ejecta, revealing sometime symmetric or asymmetric environments, sometime single or multiple events associated with mass-loss during the LBV phase. We present our EVLA and ATCA radio observations of some LBV candidates, which provide us knowledge of the ionizing flux, the distribution and the physical conditions of the ionized gas.
