A set-top box device capable of providing electrical power to an antenna includes an insulation housing, a printed circuit board, a metal portion, and a conductive locking member. The insulation housing has at least one lateral arranged thereon a through hole portion. The printed circuit board is arranged in the insulation housing and includes a power supply module. The metal portion is arranged on the printed circuit board and includes a locking hole corresponding the through hole portion. The conductive locking member passes through the locking hole, the through hole portion, a conductive end portion of the power supply line, and the metal portion. The power supply module feeds a current into the antenna through a connection of the metal portion, the conductive locking member, and the conductive end portion, and the current flows to a ground portion of the signal line thereby forming a power supply loop.
