RF coax cables are commonly called antenna cables because they are typically used to send an antenna signal from a wall outlet, or antenna wall plate, to the TV. This allows your TV to display content from satellite based sources, or content transmitted via radio waves. Antenna cables can also be used to connect certain devices such as VCR, set top boxes, AV receivers, and projectors. All cable comes previously cut and stripped for simple wiring directly into the wall outlet. Colours include red, white, and black.
