New low field side antennae have been installed in TEXTOR. At the maximum available power of 2.6 MW a doubling of electron and ion temperature is now obtained at n(e) = 2.5 x 1.0 E13/cm3. Excellent conditions for density and impurity control are achieved with appropriate antenna phasing and the use of novel wall conditioning techniques. The low metallic pollution is particularly encouraging. Important anisotropic tails are produced leading to an apparent lower confinement of the thermal plasma component but improved overall confinement. The tail also appears to play a role in sawtooth stabilisation. Excellent agreement is further obtained between theory and experiment with respect to antenna coupling, wave absorption and tail production.
