Correction to “Radio Frequency Interference and Lightning Studies of a Square Kilometer Array Demonstrator Structure” [May 2011]

We studied computational electromagnetic and scale models of a Square Kilometer Array demonstrator structure in our paper listed above (ibid., vol. 53, no. 2, pp. 543-547, May 2011). During the final publication process, one of our figures was inadvertently duplicated and the pivotal point of the paper was lost. The omitted numerical simulation would have illustrated the value of the optimized lightning down conductor (LDC). Fig. 1 here (intended [Fig. 10 in the above paper]) should be compared to Fig. 2 ([above paper, Fig. 11]). The considerably lower surface current density acheived due to the LDC reconfiguration was the purpose of the above listed work.
