According to wave propagation theory, antenna efficiency can be calculated by using field strength measured in the groundwave-dominant range. Selection of test equipment, method to calibrate the antenna factor and directional gain of a test antenna are also introduced. The calculated field strengths agree well with the measured data. As an example, the radiation efficiencies of a VLF antenna at different distance and frequencies are calculated.Read More
