S 234 (Marconi)
S 234 (Marconi) is operating in the UHF-Band airfield surveillance radar. It was derived from the wartime English radar Type 11.
It uses a single curved parabolic reflector with a width of 52½ ft fed by an off-set slotted waveguide radiator. Radar type S 234 employs a transmitter having triode output stages, while the S 234A uses a 3 stage power klystron.
