Marconi Type 11

The Marconi Type 11 is an air surveillance radar operating in the UHF-Band. It used a PPI and an A-scope. The separate transmit and receive antennas had a truncated parabolic reflector with a vertically polarized dipole feeding each.

Initial versions of the radar became operational in June 1943. Since the Type 11 Mk.5 version, the transmitter was fully coherent and crystal-stabilized.
