We present a phenomenological study of neutral gauge bosons and fermions in an extended Standard model with SU(3)C x SU(4)L x U(1)X gauge symmetry.The model includes gauge bosons and fermions without exotic charges and is distinguished by the symmetry-breaking patern SU(4)L->SU(2)L x SU(2)H x U(1)AH. This introduces an extended electroweak symmetry group SU(2)L x SU(2)H at low energies.We recover the fermion spectra of an anomaly-free three-family 3-4-1 modelwithout exotic chargesfor U(1)X charge X = T3R+(B-L)/2.The interaction of physical neutral gauge bosons Zprime,Z double prime and exotic fermions are presented along with their masses and mixing angle.The electroweak constraints from oblique corections on the model are also calculated.
