Based on previous studies that support the important role of the f2(1270), f2^\ensuremath'(1525), and K2*(1430) resonances in the J/\ensuremathψ[\ensuremathψ(2S)]\ensuremath→\ensuremathφ(\ensuremathω)VV decays, we make an analysis of the analogous decays of \mathrm\ensuremathΥ(1S) and \mathrm\ensuremathΥ(2S), taking into account recent experimental data. In addition, we study the J/\ensuremathψ and \ensuremathψ(2S) radiative decays and we also made predictions for the radiative decay of \mathrm\ensuremathΥ(1S) and \mathrm\ensuremathΥ(2S) into \ensuremathγf2(1270), \ensuremathγf2^\ensuremath'(1525), \ensuremathγf0(1370) and \ensuremathγf0(1710), comparing with the recent results of a CLEO experiment. We can compare our results for ratios of decay rates with eight experimental ratios and find agreement in all but one case, where experimental problems are discussed.
