Super long wave antenna runs in an electric medium, and the work entironment differs with traditional antennas. Propagation characters in electric medium of super long wave electromagnetic wave was studied, and the propagation law in the border between seawater and air was analysed. Some important parameters of super long wave antenna, such as pattern, effective length, input resis-tance and effective noise field, were deduced ,which makes theoretic support for deeply studying super long wave receive antennas.
