Figure 1: „Tall King A”
This antenna is something special with the measures (width: 33 meters and height: 22 meters): a parabolic dish antenna for VHF frequencies. The technical data of this radar unit corresponded approximately to those of the P 12. The transmitter was, however, more efficient (Pi=700 kW). The maximum range was 600 km while the range resolution and the bearing resolution deteriorated.
A P-14 radar unit has got two main antennae. One antenna was built up stationarily as a working antenna. The other antenna was loaded on 36 trucks by the type URAL-375-D for a transportable use. The time for erecting of the antenna was about 50 hours.
