We study properties of the compact ~4D~ U(1) lattice gauge theory with monopoles \it removed. Employing Monte Carlo simulations we calculate correlators of scalar, vector and tensor operators at zero and nonzero momenta ~p~. We confirm that the theory without monopoles has no phase transition, at least, in the interval ~0 < β≤ 2~. There the photon becomes massless and fits the lattice free field theory dispersion relation very well. The energies of the ~0++~, ~1+-~ and ~2++~ states show a rather weak dependence on the coupling in the interval of ~β~ investigated, and their ratios are practically constant. We show also a further modification of the theory suppressing the negative plaquettes to improve drastically the overlap with the lowest states (at least, for ~J=1).
