VHFbanden

The Very High Frequency (VHF) band is a segment of the electromagnetic spectrum used for various communication purposes. It is defined by the International Telecommunication Union (ITU) as the range from 30 MHz to 300 MHz. The VHF band is further divided into several sub-bands, each allocated for specific uses.

The lower part of the VHF band, from 30 MHz to 88 MHz, is primarily used for television broadcasting. This includes analog and digital television signals, as well as other broadcasting services. The middle part, from 88 MHz to 108 MHz, is reserved for FM radio broadcasting. The upper part of the VHF band, from 108 MHz to 300 MHz, is used for various communication services, including two-way radio communication, amateur radio, and other specialized applications.

The VHF band is known for its relatively short wavelength, which allows for line-of-sight propagation. This means that signals can travel directly from the transmitter to the receiver without significant interference from the Earth's curvature. This characteristic makes VHF suitable for applications that require clear and direct communication, such as aircraft communication, maritime communication, and amateur radio.

The VHF band is also used for satellite communication, particularly in the lower part of the band. Satellites in the VHF range are used for various applications, including weather monitoring, remote sensing, and scientific research.

In summary, the VHF band is a crucial segment of the electromagnetic spectrum used for a wide range of communication and broadcasting services. Its unique characteristics make it suitable for various applications that require clear and direct communication.
