N2 - High Frequency (HF) communications system at 3-30 MHz frequency utilizes ionosphere as a radio wave propagation path. HF communications system is usually used in military and civilian fields because it is easy and relatively inexpensive to use. In the implementation, there are areas that cannot receive the signal called skip zone unreached by reflected wave. One way to eliminate skip zone area is to implement HF communications system using NVIS (Near Vertical Incidence Sykwave). In addition, to increase the availability of channels in HF communication system, a MIMO 2×2 antenna system can be implemented by installing 2 antenna's mounted orthogonally on each transmitter and receiver. MIMO HF NVIS channel modeling requires channel response measurement. Therefore, the authors design a measurement system to obtain the channel response as the basis of HF MIMO NVIS channel modeling. With 20 Watt transmitter power, we have successfully tested the availability of Surabaya-Malang links. The result obtained is that the measurement system of MIMO 2×2 produces 4 channel response, which is processed using product detector and LPF with Hamming Window technique.
