1. A transmission line for a downhole tool, the transmission line comprising a generally tubular outer conductor with a high strength material adjacent a highly conductive material; an inner conductor generally co-axially disposed within the outer conductor, and a dielectric material disposed intermediate the inner and outer conductors, the dielectric material intially loosely fitted relative to at least one of the outer and the inner conductors; wherein at least one of the outer and the inner conductors is further deformed to provide an interference fit with the dielectric material, such that independent motion between the outer conductor, inner conductor, and the dielectric material is substantially abated during deployment of the downhole tool.
