The properties of three BL Lacertae objects, namely Mrk 180, Mrk 421, and Mrk 501, were investigated using data gathered at UV, X-ray, optical, and radio wave lengths. From each time frozen spectrum an inhomogeneous, relativistic jet model was computed. It is noted that the UV is the one spectral region where synchrotron emission is seen uncontaminated by galactic emission, self-Compton emission, or optical depth effects. A steepening synchrotron emission spectrum from the IR to the UV, which is characteristic of relativistic jets, is present in the jet model that was developed.
