The 28 MHz antenna in the middle is not often used due to poor ionospheric propagation nowadays. An auxiliary 28 MHz antenna up front against a forest of 70-cm arrays. The total number of antenna ...
First, the numerical model of the long-distance propagation of LEMP in the Earth-ionosphere waveguide (EIWG) is constructed by using the auxiliary differential equation finite difference time domain ...
The Bureau of Meteorology's Ionospheric Prediction Service (IPS) offers radio propagation, geophysical and space weather services to Australian and overseas agencies. The IPS team has a diverse ...
