By the way, if I understand it correctly - there is a transmitter completely contained in K4, waveguide goes out of K4 to a wavesplitter and the "antennas to be destructed" are simply waveguides with feeders. So in case IRZ anetnna is hit, nothing of great value is destroyed, because all electronics is contained in a K4 van.

Is K4 somehow connected to K1? I mean if it transmits only when RPC is transmitting and if it change for example wave type (MXI, FKM....) according to RPC?
