WRK-200

WRK-200 is operating in C-Band Doppler- precipation radar with dual polarization.

The weather radar uses a klystron of type VKC 8387 as power-amplifier transmitter. The center-fed parabolic reflector has a diameter of 4.5 m. The double superhet receivers are located directly on the antenna to avoid receiver-line losses.
