Methods, a system and antennas are provided for transmitting or receiving signals from a hydrocarbon production well. The well comprises a well bore formed in a formation, a production liner/tubing extending axially along the well bore, and an inductive coupling disposed around the liner/tubing. The liner tubing is electrically coupled to the formation at two axially separated locations and is electrically isolated from the formation between the locations. For transmitting, an alternating current signal to the inductive coupling to induce a current in the liner/tubing, the liner tubing forming a dipole antenna that generates an electromagnetic radiation signal propagating through the formation. For receiving, the dipole antenna is exposed to an electromagnetic radiation signal propagated through the formation which induces an alternating current signal in the tubing and the current signal is detected at the inductive coupling.
