Abstract

Underground radio propagation measurement is an interesting work as its application very much helping on enabling radio through the earth (TTE) application. TTE enablesunderground work to communicate with people on surface. The ground consists of various materials rapidly degrading signal level. This paper performs an experiment to enable frequency of 109.8 MHz to be used as radio to the earth application. The mathematical model is used to predict the attenuation pattern. However, as model proposed by different measurement places, an experiment by measuring directly to ground attenuation is conducted to confirm the model precision. The measurement shows significant error up to 16.18%, which results some parameters adjustment on the model. By adjusting the earth parameter, error is reduced to 11.17%.
