Cable TV wire comes in three types: RG-6 (heavy duty all weather above and underground), RG-11(medium duty indoor-outdoor) and RG-59 (light duty indoor). All three are coaxial; that is they have at least one layer of negative ground shielding and a center pole of copper-coated solid wire wrapped in plastic. When adding another TV receiver or high speed cable Internet, the single line entering your home or office needs to be split into two or more lines to accommodate the new devices. To do this you need a 75 ohm coaxial line splitter available in two, three, four or more outputs and additional cable. Signal loss can occur if output demand exceeds input signal strength (see Warnings). Tips Warnings Writer Bio
