A satellite cable, sometimes known as a coax cable, is an electrical cable that transmits radio frequency (RF) signals from one point to another.At present, the commonly used satellite coaxial cable is 75-5 type, which is a "double insulation double shielding" coaxial cable, its core wire, insulation layer, shielding layer is still the standard 75 ohm cable, but the difference is that outside the original shielding layer, a second layer of insulation and a second layer of shielding layer is added, and the outer sheath is added, so the anti-interference performance is excellent.
