What is the FM radio band range?

Answer 1

Radio waves, or other electromagnetic waves, just go on, and on, and on.

ADDED. They do, assuming nothing is in their way, but they are attenuated by distance, by an inverse-square law, so eventually they are too faint to detect.

Answer 2

In principle, it never ends, and the distance is infinite.

The real question is: "At what distance is the signal strength from the FM station

so low that your best receiver can't detect it ?"

As long as nothing completely blocks it, there's no limit to how far it travels. But the radio energy keeps getting thinner and more spread out as it travels farther. So the real question is: How far away from the source can you collect enough of the radio energy to be able to listen to it ?

Answer 3

1. High power - to the moon and back, or further.

2. Common broadcast transmitters, a few metres to thousands of kilometres. 774 ABC Melbourne routinely covers the state of Victoria - around 300 km-plus.

Answer 4

The FM radio band range for the United States is between 88.1 and 108.1 in frequency. The AM radio band range for the United States is between 540 and 1600, but is used less frequently than FM radio.

Answer 5

Radio Astronomy is the technique of studying astronomical objects by receiving radio waves
emitted from them. The objects include some that are billions of light years distant from us.

There's no limit to the distance that a radio signal can travel. But its power spreads out
over a wider area as it travels, so the farther it has gone, the 'thinner' it seems to an
antenna trying to receive it.

So, the question is not "How far can the wave travel ?"

The question is "How far can it go before I can no longer detect it with the technology that I have ?"

Answer 6

FM radio ... as well as AM radio, Fire and Police radio, microwave radio, ambulance and taxi radio,

walkie talkie radio, GPS radio, garage-door-opener radio, RC toy radio, radio communication with

Mars rovers and astronauts aboard the Space Shuttles and International Space Station, bluetooth,

and satellite or open-air television ... are all transported in the form of electromagnetic waves at

various different frequencies (wavelengths).

Answer 7

Radio waves, or other electromagnetic waves, just go on, and on, and on.
