Mottakerantenne

Mottakerantenne, also known as a receiving antenna or passive antenna, is a type of antenna used to receive electromagnetic waves, typically in the form of radio frequency signals. The term "mottakerantenne" is primarily used in Scandinavian countries, including Norway, Denmark, and Sweden.

A receiving antenna is designed to collect and focus incoming electromagnetic waves onto an electrical component, such as a diode or a transistor, where they can be converted into an electrical signal. This signal can then be amplified, processed, and used to decode audio, video, or data information.

Mottakerantenne designs can vary from simple to complex, depending on the frequency range and application. For example, a simple wire antenna can be used to receive longwave signals, while a satellite dish is a more complex example of a receiving antenna, designed to collect microwave signals from satellites in orbit.

Receiving antennas are used in a wide range of applications, including radio broadcasting, satellite communications, and amateur radio. They can be mounted on buildings, rooftops, or in open fields, depending on the height and location required for optimal signal reception.

The term "mottakerantenne" specifically refers to the receiving antenna used in Scandinavian countries for receiving radio signals. The name is derived from the Norwegian word "mottaker," meaning receiver or recipient, and "antenne," which means antenna.
