These 75 ohm coaxial RCA cables are perfect for just about any application. They can be used as a good video cable, sub-woofer cable, or anything else that you want a good shielded RCA cable for. You can use them in pairs for a high-end Left/Right Analog cable, or 3 of them for Component Video cables. These are also really good when used with adapters, to solve other hard-to-solve configurations. For example, you could put a couple of our part #201304 (RCA Female to 1/4" Mono Plug) to make a good quality long 1/4" mono cable. Or use part #251-200 (RCA Jack to 3.5mm Mono Plug) to make a 3.5mm Mono Cable using 75 ohm coax cable. Or, use a combination of adapters, like a BNC and 3.5mm or 1/4" to make a custom BNC to 1/4" cable 100 feet long. There are a lot of problems that can be solved with these high quality 75 ohm Coax RCA Cables, especially when you consider that we have them in many sizes from 3 feet to 100 feet in length.
