## What is the wavelength of FM radio?

2.78 to 3.41 meters

Wavelength from Frequency What is the wavelength of their carrier signal? If you do this for the two ends of the FM range, you’ll find out that the FM range in wavelength is 2.78 to 3.41 meters.

**What will happen if the length of the antenna is the same with the wavelength of the frequency?**

The length of the antenna is inversely proportional to the frequency and directly proportional to the wavelength. The higher the frequency and the shorter the wavelength, the shorter the antenna can be made.

**What is a full wave antenna?**

Advertisements. If the length of the dipole, i.e. the total wire, equals the full wavelength λ, then it is called as full wave dipole. If a full wavelength dipole is used either for transmission or for reception, let us see how the radiation will be.

### How long is a full wave GMRS antenna?

The GMRS J-Pole is tuned for maximum performance on the 462 – 467 MHz General Mobile Radio Service and UHF public safety band….Additional information.

**What is the length of antenna needed to a signal of 900 MHz frequency?**

approximately 16.6cm

For a dipole antenna to operate optimally at its specified frequency, its length must be equivalent to a half wavelength of the operating frequency. In the 900 MHz range, this equals approximately 16.6cm (a full wavelength is 33.3cm).

**What is the relation between antenna length and wavelength?**

#### How do you find the wavelength of FM radio waves?

The wavelength (λ) of a radio wave can be calculated by dividing the speed of light (c = 299 792 458 m) by the frequency of the radio wave. The formula for calculating the wavelength of a radio wave: Wavelength = λ = c/f; where f is the frequency in Hertz and c = 299792458 m/s.

**What is the wavelength of a 100 MHz FM radio wave?**

Worldwide FM radio is operating in VHF band II between 87.5 MHz and 108.0 MHz….

Frequency | Wavelength |
---|---|

100 MHz = 100,000,000 Hz = 108 Hz | 3 m |

1000 MHz = 1000,000,000 Hz = 109 Hz | 0.3 m |

**Which size of the antenna should have comparable to the wavelength?**

For efficient radiation and reception, the height of transmitting and receiving antennas should be comparable to a quarter of wavelength of the frequency used. So for efficient transmission of signals of wavelengths λ the minimum length of antenna should be λ/4.
