Today, cable consumers don’t use the old way of sending cable TV over coax. If you own a TV, you probably know that it needs a cable box. Typically, the more the materials used in the manufacture, the higher the cost of manufacture. The main reason for its high price is its thickness and the type of conductor integrated into the cable. This means that its price can also be quite expensive if used for long distances. The biggest downside of the RG11 cable is its high price per meter. What’s more, the RG11 has a higher frequency and can guarantee better signals when used with a shorter cable. RG6 cables tend to have greater attenuation as compared to RG11. The main difference between these two types is the degree of signal, also known as attenuation. You can also use them for transmitting analog video signals and serial digital interface signals – in these cases, the shielding is heavier to improve impedance stability. Their primary use is routing cable TV signals within homes. RG6 cables have a characteristic impedance of 75 ohms. RG11 and RG6 are the most common types of coaxial cables for an AV system. By now, you probably know that professionals use different cables for satellite installations and TV.
