The U.S. Naval Research Laboratory experimentally determined the radiation parameters, radiation resistance and effective height, of the very low frequency VLF transmitting station NWC at the U.S. Naval Communication Station, North West Cape, Australia. The work was carried out in January and February 1967 as part of the Proof of Performance evaluation of this new transmitting station. The radiation parameters were determined for five operating frequencies 14.2, 15.5, 19.8, 22.3, and 27.3 kcs, with transmitting antenna operating with all six of its top-loading panels. The parameters were also determined for the antenna operating with five panels but at only four frequencies 15.5, 19.8, 22.3, and 27.3 kcs. The values for the radiation parameters of the NWC transmitting system are reported and discussed along with a detailed discussion of the experimental techniques and data reduction processes.
