Abstract
A rigid RF coaxial transmission line is positioned within a wellbore in a subterranean formation. The rigid RF coaxial transmission line includes a series of rigid coaxial sections coupled together in end-to-end relation and to be positioned within the wellbore of the subterranean formation. Each rigid coaxial section includes an inner conductor, a rigid outer conductor surrounding the inner conductor, and a dielectric therebetween. Each of the rigid outer conductors has threaded ends. The rigid RF coaxial transmission line includes a respective connector between adjacent ones of the series of rigid coaxial sections, each connector having a rigid outer layer threadingly secured to respective threaded ends of adjacent rigid outer conductors, and an electrically conductive liner carried by the rigid outer layer and defining an electrical joint between the adjacent rigid outer conductors.
