Mark II (or MKII or Jodrell Bank Mark II) is a radio telescope at Jodrell Bank Observatory, in north-west England that went into operation in 1964. It is elliptical, with a 38m major axis and an 25m minor axis. It was used in early very-long-baseline interferometry experiments and is still used for such observations.
