Oborona “Tall King C”
The Oborona is the direct successor of the P-14 “Tall King” and got the NATO-Codename “Tall King C”. The antenna has to be mistaken for that one of the P-14 only on the first look. Optical differences at the antenna are:
- a wider reflector and another radiator system,
- the compensation antennae behind the parabolic reflector,
- the “stork's nest” at the tip of the pylon.
The Oborona usually worked together with a height-finder of the type PRV-17. The radar unit in everyone parameters has also electrically improved:
- the better antenna gain with lower side lobes and back-coil,
- higher reach, (therefore a longer reception time needed)
- modified secondary surveillance radar Kremny 2 (The right-angled antenna of the interrogator is shown in the picture under the back-lobe-compensation antenna)
