Coax cable is used to connect many electronics devices, including televisions, DVD players, cable television boxes, radio antennas and computers. The standard coax cable consists of an inner conductor, outer conductor and an outer layer of insulation material. Although, both the inner and outer conductors are made of metal, they both have some resistivity that causes power loss as the signal travels down the conductors. This loss is referred to as signal attenuation. Pure attenuation calculations are complicated, requiring the use of higher order mathematics. However, you can shortcut the approximations with the aid of manufacturer or industry cable data. Writer Bio
