Radio observations have been made of a sample of optically selected bipolar nebulae, to examine their spatial structures and to determine the nature of the sources which excite them. IRAS point source survey data, sub-millimeter wavelength molecular line and continuum measurements have been combined with the radio data to constrain the estimates of the nature of the excitation sources. Two thirds of the sample are found to be associated with luminous (L > 1000 L⊙) objects which are characterized as ZAMS B0-B2 stars. Several cases show characteristics of ionized outflowing gas, and may be pre-main sequence objects. The remaining third of the sample have ZAMS exciting stars between B3 and A5.
