Abstract:
1. A protective device for transmitting electromagnetic signals of a desired frequency band, said protective device comprising: (a) an outer conductor, (b) an inner conductor extending coaxially within said outer conductor, said inner and outer conductors being spaced apart, (c) a radio frequency impedance control (RFIC) tube disposed between said inner conductor and said outer conductor to control the impedance of said inner conductor, the RFIC tube being shaped to define an opening, and (d) a shunt conductor for shunting electromagnetic signals traveling within said inner conductor which fall outside of the desired frequency band, said shunt conductor comprising a first end, a second end and an intermediary portion which connects the first and second ends, the first end of said shunt conductor being coupled to said inner conductor and the second end of said shunt conductor being coupled to said outer conductor, (e) wherein the intermediary portion of said shunt conductor is non-linear along the entirety of its length and comprises first and second contiguous curved portions, the first portion extending out from said inner conductor and through the opening in said RFIC tube along a first curved path, the second portion of said shunt conductor wrapping around said RFIC tube along a second curved path.
