We replace the standard model scalar doublet by a doublet of vector fields and generate masses by dynamical symmetry breaking. Oblique radiative corrections are small if the new vector bosons (B+, B0) are heavy. In this note it is shown that the model has a low momentum scale and above A ≃ 2 TeV it does not respect the perturbative unitarity. From tree-graph unitarity the allowed region of B+(B0) mass is estimated as mB+ ≥ 333 GeV (mB0 ≥ 373 GeV) at Λ = 1 TeV.
