Zusammenfassung:	An RF antenna assembly may be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery. The RF antenna assembly includes first and second tubular conductors and a feed structure therebetween defining a dipole antenna to be positioned within the wellbore, and an RF transmission line extending within one of the tubular conductors. The feed structure includes a dielectric tube, a first connector coupling the RF transmission line to the first tubular conductor, and a second connector coupling the RF transmission line to the second tubular conductor.
