A surge protector connector comprises a surge protector having a front plate, a rear plate, and hollow cylindrical body bridging the front and rear plates. A coaxial cable connector interface extends from the front plate, and the connector interface is constructed and arranged to detachably engage with a mating coaxial cable connector at the end of a first coaxial cable. A cable attachment interface extends from the rear plate, and the cable attachment interface is constructed and arranged to attach directly to a prepared end of a second coaxial cable free of another coaxial cable connector interface. The surge protector connector further includes coaxial inner and outer conductors extending through the hollow cylindrical body and extending between the cable attachment interface and the coaxial cable connector interface. The surge protector includes a curvilinear quarter-wavelength shorting stub having a first portion extending in a generally radial direction from the inner conductor through a gap in the outer conductor and a second portion extending in a generally annular direction circumscribing the outer conductor between the outer conductor and the cylindrical body.
