P-14
The P-14 radar (Russian name: 1RL113 “Lena”; Cyrillic: 1РЛ113 «Лена»; NATO designation: “Tall King A”) was built starting in 1959. With the dimensions of 32 m · 11 m, this parabolic antenna took a special appearance in the VHF range. The antenna rotates up to a wind speed of 30 m/s. The technical data of the radar station were approximately the same as those of the P-12, but the transmitter was more powerful (Pi ≥ 700 kW). The maximum displayed range was 600 km, while range resolution deteriorated due to screen resolution.
A P-14 had two main antennas. One of them was set up stationary as the actively used antenna. An additional antenna was ready for deployment put on 36 URAL-375D type vehicles. The setup time for the antenna was about 50 hours.
The last radar was delivered in 1979. A total of 731 stations were built, 24 of which were exported.
