  In this article, we present a detailed study of the masses of all gauge
bosons, as well as explaing recent experimental data regarding the $W$-boson
mass presented by the CDF collaboration and even possible changes that these
data can bring to experimental measurements of the masses of $Z$-boson mass in
the context of the Minimal Supersymmetric $SU(3)_{C}\otimes SU(3)_{L}\otimes
U(1)_{N}$ Model. We also intend to show a phenomenological analysis of possible
mixtures of gauge bosons in this model. We will show that our numerical
predictions for the masses of the physical gauge bosons are within the current
experimental limits.
