Abstract. We find a mapping between antisymmetric tensor matter fields and the Weinberg's 2(2j+1)- component ``bispinor" fields. Equations which describe the j=1 antisymmetric tensor field coincide with the Hammer-Tucker equations entirely and with the Weinberg ones within a subsidiary condition, the Klein-Gordon equation. The new Lagrangian for the Weinberg theory is proposed which is scalar and Hermitian. It is built on the basis of the concept of the `Weinberg doubles'. Origins of a contradiction between the classical theory, the Weinberg theorem B-A=\lambda for quantum relativistic fields and the claimed `longitudity' of the antisymmetric tensor field (transformed on the (1,0)+(0,1) Lorentz group representation) after quantization are clarified. Analogs of the j=1/2 Feynman-Dyson propagator are presented in the framework of the j=1 Weinberg theory. It is then shown that under the definite choice of field functions and initial and boundary conditions the massless j=1 Weinberg-Tucker-Hammer equations contain all information that the Maxwell equations for electromagnetic field have. Thus, the former appear to be of use in describing some physical processes for which that could be necessitated or be convenient.
