                         matter candidate annihilating into 2-lepton and 4-lepton final 
                         states. We then compare our results with the known radio 
                         measurements of the sky temperature as a function of the 
                         frequency. In particular, we calculate the radio emission for some 
                         dark matter candidates annihilating into intermediate bosons that 
                         subsequently decay into a 4-lepton channel with a thermal 
                         annihilation cross-section. We show that within the range of 
                         frequencies from 20 MHz to 5 GHz, this channel can produce a 
                         stronger signature than direct annihilation into leptons.",
