Koaxialpfad

Koaxialpfad, also known as coaxial cable, is a type of electrical cable that consists of a central conductor surrounded by a tubular insulating layer, which is then surrounded by a cylindrical conductive shield. This shield is typically braided or foil and is connected to the cable's outer conductor. The entire structure is then enclosed in a protective outer jacket. Coaxial cables are widely used in various applications due to their excellent signal transmission properties, including low signal loss, high bandwidth, and resistance to electromagnetic interference.

The primary advantage of coaxial cables is their ability to carry high-frequency signals over long distances with minimal attenuation. This makes them ideal for applications such as television broadcasting, cable television, and high-speed internet connections. Additionally, the shielded design of coaxial cables helps to prevent external electromagnetic interference from affecting the signal, ensuring a cleaner and more reliable transmission.

Coaxial cables are available in various types, including RG-6, RG-59, and RG-11, each designed for specific applications based on their impedance, bandwidth, and signal loss characteristics. The RG designation stands for "Radio Guide," a term used during World War II to describe these cables. The numbers following the RG designation indicate the cable's impedance, with lower numbers generally representing higher impedance and better performance at higher frequencies.

In summary, coaxial cables are a versatile and reliable medium for transmitting high-frequency signals over long distances. Their unique design and properties make them indispensable in modern telecommunications and broadcasting systems.
