Abstract:

Measurements of the performance of a nine-conductor VLF antenna, 10.5 km long, laid on a lava bed at the Naval Weapons Center China Lake, are presented. Theoretical curves are presented to show the improvement in radiation efficiency and bandwidth that can be realized if the antenna is elevated a few feet above the lava and the individual conductors are loaded with the proper series capacitance to increase the antenna wave velocity.
