1. An apparatus for providing direct current (DC) power to a radio, comprising:
a power supply comprising (a) a first input that is configured to receive a first DC power signal and (b) an output configured to be coupled to the radio through electrical conductors; and
wherein the power supply is configured to provide the output with a second DC power signal having a first voltage level;
wherein the power supply is further configured to adjust, at the output, the first voltage level of the second DC power signal and to provide, at ends of the electrical conductors that are remote from the power supply, a second voltage level of the second DC power signal that is larger than a nominal power signal voltage level of the radio and that is less than a maximum power signal voltage level of the radio.
