The radio field environment is very different according to frequency band, therefore communication condition is equation that VHF is passed by direct radiation and HF is via reflect radiation in ionosphere. Load a ship according to the enforcement regulations of the ships safety act have specificated the radio equipment that should be operating. This paper have analysed by the simulation program about radio field environment for research the communications condition, which is VHF & HF band in domestic coastal. We have Predicted to radio field environment and communications condition using the data of analysis and domestic radio regulation regard to coast navigational ship. Therefore have proposed the necessity for rationally plan on improvement the radio regulation and network cooperation of VHF radio station.
