Abstract

this study is still an initiation stage for implementation in Northern Maluku Archipelago. Because of the characteristics of the archipelago and many black spots in rural area. An alternative research is conducted to overcome technical problems in rural areas of the archipelagoes. One of the alternative technologies is using of HF (High Frequency) radio waves which are working at a frequency of 3 to 30 MHz, it’s used for long-distance radio communication due to the nature of its waves can be reflected by the ionosphere, the airwaves (sky wave) emitted, depending on the frequency, timing and conditions of the ionosphere, HF radio communication NVIS (Near Vertical Incident sky wave) able to cope with the skip zone so as not to affect the quality of emission, whether grasslands, dense forests, mountain slopes etc. The methodology is using ITURHFProp software, there are two parts of sub-programs, namely P533 () and ITURHFProp (). Link Budget is a power budget estimated that needs to be taken into account to ensure that the acceptance level is well received. Link budget calculation has an important role so that the communication network design can achieve optimum and efficient results both in terms of technical reliability and in terms of cost. NVIS is a reflection of the times by a layer of F / F2 ionosphere, the beam (signal) HF radio for communication with the emitting angle almost perpendicular beam (Near Vertical) upon approaching 90°. The reflections results have varied angles, with coverage communication distance up to 300 km.
