Abstract
A device for heating hydrocarbon resources in a subterranean formation having a wellbore therein may include a tubular radio frequency (RF) antenna within the wellbore, and a tool slidably positioned within the tubular RF antenna. The tool may include an RF transmission line and at least one RF contact coupled to a distal end of the RF transmission line and biased in contact with the tubular RF antenna. The tool may also include an anchoring device configured to selectively anchor the RF transmission line and the at least one RF contact within the tubular RF antenna.
