Comments related to reading the paper "Static quantities of the $W$ boson in the $SU_L(3)\times U_X(1)$ model with right-handed neutrinos", hep-ph/0312308 (by J. L. Garcia-Luna et al) are given. They do not concern the main results of the paper but a statement there about the Higgs sector of the 331 model with right-handed neutrinos. The scalar sextet introduced here may help us to generate neutrino masses in an acceptable range.
