Impedances of Submerged Horizontal Wire Antennas
Abstract
Experiments have been conducted to check the validity of the theoretical equations for the input impedance of horizontal type end-sealed and end-exposed antennas submerged in sea water. Scale model techniques were employed which require the use of a specially designed model range free of boundary effects and reflective interference. The end-sealed and end-exposed antennas are compared to open-circuited and short-circuited standard transmission lines. It is shown that the impedances of the antennas and transmission lines are of the same general characteristics. A scaling factor of twelve to one was employed over the frequency range of 0.1 to 10 Mc, which adequately embraces the full scale range of frequencies, 10 to 500 kc, considered of practical value for underwater radio systems. Good agreement is shown between the experimental and theoretical values.
