I wonder how useful the lock on after launch capability of the S-200 is, for which the large data-link dish of the 5N62 would be used. If a LOAL system is operationally useful for the S-200, then the question arises whether the two directional antenna feed horns of the receiver truck mentioned above would be sufficient to maintain data-link with the S-200 missile at longer ranges, because its much smaller than the data link dish of the 5N62.
S-200 does NOT have any datalink. What is questionable is RPC frequency sampling ability of the missile, but it does not even come close to any datalink. There are three antennas on 5N62 - transmit, receive and KRO (which you probably mean is used for datalink (similarly to S(A)-75 RPK antenna), but it in fact receives signal from missile in flight which indicates that missile's GSN has lost the target lock).
Lock on after launch is used in S-200 in cases where for example trees block line of sight from missile's GSN to target. Because RPC is usually located on an elevated platform in such cases, so it does see the target at the moment of lauch, while the missile does not.
