Gigatronix coax is a type of coaxial cable used for transmitting high-frequency signals. It consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer. The central conductor is typically made of copper or aluminium, while the insulating layers are usually made of materials like polyethene or Teflon. The metallic shield helps to minimize signal loss and interference. Gigatronix coax is commonly used in applications such as telecommunications, cable television, and computer networking. It provides reliable and efficient signal transmission, making it a popular choice in various industries.
