Separate antennas are used for launching and receiving the signal. The antennas are located in the equatorial plane of the toroidal cross-section at φ = 135° (between [[TJ-II:Sectors|sectors]] A4 and A5), and view the plasma from the low-field side. | Separate antennas are used for launching and receiving the signal.
