Partly insulated wire antenna for electric field and air-earth current measurements in the free atmosphere
Abstract
A model of partly insulated wire antenna for free-atmospheric electric field and air-earth current measurment is discussed, giving the results of test soundings and estimated measurement errors. The antenna consists of two 12-m-long wires suspended below a balloon. The effects of partial insulation on electric field distribution are studied, showing that it causes an increase and stabilization of the effective separation of antennas, allowing for a more accurate measurement of electric field and a decrease in error produced by inductive interaction between the upper and lower antenna. The insulation causes decreased sensitivity in air-earth current measurement and reduces the effective collecting area of the antenna.
