Are FM transmitters legal?
ILLEGAL FM TRANSMITTERS These transmitters claim to operate anywhere from a half watt (500 mw) to over 7 watts.
While they may claim to be FCC legal, they are not: Transmitters like the three shown above ARE ILLEGAL FOR SALE OR USE IN THE UNITED STATES, CANADA, JAPAN AND THE EUROPEAN UNION..

Can I turn my phone into a FM transmitter?
Some Android phones come with built-in FM transmitter functionality, in which case you can use this natively or with a free app such as Quick FM Transmitter and then broadcast the MP3 and other audio files on your phone to your car radio.
What is the least used FM frequency?
The lowest and almost-unused channel, channel 200, extends from 87.8 MHz to 88.0 MHz; thus its center frequency is 87.9 MHz.
How can I increase the range of my FM transmitter?
To increase transmission range, the antenna gain and height must be increased for both systems. There are two ways to increase the antenna gain. 1. Stacking (adding) antennas to increase antenna power gain.
What is the range of FM transmitter?
They are often used in cars but may also be in fixed locations such as broadcasting from a computer sound card throughout a building. Being low-powered, most transmitters typically have a short range of 100–300 feet (30–100 metres), depending on the quality of the receiver, obstructions and elevation.
How far will a 15w FM transmitter broadcast?
At 15 watts, the range increases to 5 miles, at 40 watts to 10 miles and at 100 watts to 15 miles. The general rule of thumb is it will take four times the power to double the transmission distance. Increase the transmission range of the FM antenna without increasing the power by raising the antenna.
How far will 25 watts transmit?
For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.
Are FM transmitters good?
Features to Consider in Good FM Transmitters Transmitters with a stable frequency are considered the best. … For example, the best FM transmitters can connect to smartphones and mp3 players to broadcast music and podcasts. Sound Quality: The FM transmitter is only as good as the sound quality.
How far can a 2 watt radio transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)Average Range Guidelines *WattageFlat Open Terrain (miles)Inside Buildings (floors)1 watt (UHF)2 – 36 – 82 watts (UHF)3 – 415 – 202 watts (VHF)3 – 59 – 115 more rows
Are FM transmitters dangerous?
There are newer exposure limits for working on towers in the U.S.. But the power fades rapidly with distance. In any case if you consider cellular transmitters bad for you, FM broadcast would be about 100–1000 times worse. Human body is affected by the strength and frequency of radio waves.
How far will a 50 watt FM transmitter reach?
If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles. If 1 Million Watts of power is used, it is very likely that signal will only propagate just over 20 miles.
