RG11 cable is a type of coaxial cable used for various high-frequency signal transmissions, such as television, internet, and other data communications. It is thicker and offers better performance over longer distances compared to RG6 cable. When terminated with F connectors, RG11 cable is suitable for applications requiring robust and reliable signal transmission. Here’s an overview of RG11 cable with F connectors:
Key Features of RG11 Cable:
