Measurement of Ground Constants by Wave Tilt, Using Horizontal Polarization
Abstract
This report covers the research undertaken in measuring conductivity and dielectric constant of the ground at radio frequencies by using a horizontally polarized wave (set up by a local elevated transmitter) and a loop direction finder arranged to indicate vertical angles. There are described and shown two sets of transmitting and receiving apparatus which were used, and the sites for which the ground constants were measured. Included as an appendix is a brief digest of methods and results obtained by others, during the last decade, for the measurement of ground constants. Most of the work involved development of method rather than taking and reporting of a large number of ground conductivity measurements.
