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 power helps to penetrate any obstructions. Given this, when engineering and planning a station it is always better to consider the issues that limit the range. Range Is Limited By: 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. It is typically measured in watts (W) or milliwatts (mW). FM transmitters can range from low-power applications (a few milliwatts) to high-power broadcasting stations (several kilowatts). The antenna is a device used to radiate the FM signal into space. It converts electrical signals into radio waves and vice versa. An FM transmitter broadcasts a signal in the frequency range 88-108 MHz. The transmitting antenna emits the electromagnetic waves that carry the signal. The coverage of an FM transmitter and its antenna system is determined by the power of the signal and the sensitivity of the receiver.

How far can the FM transmitter transmit? How to calculate it? When we set up a radio station, all we know is the area that needs to be covered. But how many watts of FM transmitters can meet the requirements, we are usually uncertain. And this article can give you some ideas and methods. Detail Maximizing FM Transmitter Coverage: Factors, Tips, and Techniques FM transmitters, short for Frequency Modulation transmitters, play a vital role in radio broadcasting. They are electronic devices that convert audio signals into radio waves and transmit them over a specific frequency range. Personal FM transmitters are commonly used as a workaround for playing portable audio devices on car radios that don't have an Auxiliary "AUX" input jack or Bluetooth audio connectivity. They are also used to broadcast a stationary audio source, like a computer or a television, around a home. FM — frequency modulation. modulator — a circuit designed to add information to a carrier. modulation index pertains to an FM or PM transmitter. The ratio between carrier-frequency deviation (in hertz) and modulating frequency (also in hertz).

The effective service range of a carrier current station is approximately 200 feet (61 meters) from the power line; however, a carrier current signal will not pass through a utility transformer. 1 Best Overall FM Transmitter Nulaxy NX12 Check price at Amazon USB port (#): Yes (3) | Bluetooth Connection Confirmation (type): Yes (beep) REASONS TO BUY Compact Volume dial REASONS TO AVOID Hard to access ports Slight buzz when charging The Nulaxy NX12 is a compact FM transmitter with a similar profile to a standard USB car charger.
FM transmitters typically operate in the 87.5-108 MHz range, but some models may offer a wider range. If you plan to use the transmitter in a crowded area, it may be beneficial to choose a model with a wider frequency range to avoid interference from other devices. Amazon carries a long-range FM transmitter which is claimed to have 0.5 watts output and a range of up to 3 miles. Even if the 3 mile number is under unusual circumstances, 500 feet from 0.2 watts seems entirely reasonable. EDIT - As has been pointed out, the desired distance is 500 meters, not 500 feet.

FM broadcasting is a method of radio broadcasting that uses frequency modulation ( FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio. Nulaxy KM18: Best Overall FM Transmitter.
