Uhf Propagation Measurements Through The Antarctic Firn At Concordia Station

In this paper we present and discuss the first series of results obtained during a propagation measurement campaign carried out at the French-Italian Concordia research station during last (2019/2020) summer campaign in Antarctica. Specific instrumentation has been designed and assembled, essentially consisting of a transmitting unit and a receiving one, to be let down into two boreholes in the firn. Preliminary measurement results are presented and discussed.
