Archived from the desk of @mytunein . Com (Radio Directory) In Accra Transmitter Range: How Far Will My FM Radio Transmitter Travel? Many FM radio owners, managers and practitioners often ask "How many kilometers will my 5 watts, 15 watts, 30 watts, 50 watts, 100 watts, 300 watts, 500 watts, 1kW, 2kW, 3kW, 5kW transmitter go?". These questions do not have a simple or a single answer. The reason is, there are so many factors that will determine how far your transmitter will travel. In theory, the range of a transmitted radio signal is infinite regardless of power used, basically it goes on and on forever until it encounters an obstruction. More transmitter power helps to penetrate any obstructions. Given this, when engineering and planning a station it is always better to consider these factors that limit the range. Factors that will determine the range of an FM transmitter or how far it can reach include the amount of output power of the transmitter (TPO), the type of antenna used, the type of coaxial cable used, the length of coaxial cable used, the height of the antenna above average terrain (HAAT), the amount and height of trees in the area around the antenna, the amount and height of buildings around the antenna, the type of terrain surrounding the antenna site whether flat or hilly. Â FM A and FM B using a 100 watts FM transmitter with 2 bays antenna system, FM A will be getting 24 kilometers (15 miles) while FM B only gets 1.6 kilometers (1 mile). The reason is simple. FM A getting 15 miles (24km) has its 2 bays antenna mounted on a 150 foot tower/mast or on a 15 storey building located on top of a hill with gradually downward sloping terrain in all directions while FM B has a cheap home made 2 bays antenna or same as FM A mounted on a 1 storey building or on a 10 foot pole that is at ground level and the terrain slopes upwards in all directions around it or in a city where there are very tall buildings.
