A surge protector includes a coaxial through-section having a through inner conductor and a through outer conductor, a stub having a stub inner conductor, a stub outer conductor, a first end and a second end. The stub is coupled to the coaxial through-section, wherein the stub inner conductor is conductively coupled to the through inner conductor at the first end of the stub, and the stub outer conductor is conductively coupled to the through outer conductor at the first end of the stub. The stub inner conductor is substantially hollow and having at least one helical aperture disposed therein. A charge elimination device conductively coupled between the stub inner conductor and a grounding device, and a radio frequency short circuit bypass is electrically coupled between the stub inner conductor and the stub outer conductor. A DC injection port is also conductively coupled between the stub inner conductor and the stub outer conductor.
