A linear realization of a model of dynamical electroweak symmetry breaking describing additional heavy vector bosons is proposed. The model is a SU(2){sub L}{circle_times}U(1){circle_times}SU(2){sub L}{sup {prime}}{circle_times}SU(2){sub R}{sup {prime}} gauge theory, breaking at some high scale u to SU(2){sub weak}{circle_times}U(1){sub Y} and breaking again in the standard way at the electroweak scale v to U(1){sub em}. The model is renormalizable and reproduces the standard model in the limit u{r_arrow}{infinity}. This decoupling property is shown to hold also at the level of radiative corrections by computing, in particular, the {epsilon} parameters. {copyright} {ital 1997} {ital The American Physical Society}
