The number of potential sources of interference such as mobile phones is constantly increasing. It is all the more important that cables of all types are optimally shielded. That's why we don't content ourselves with the 75 dB standard screening that is usual today. With the Lokamman cables, it is a whopping 135 dB, which ensures that the received signal arrives at the receiver without loss even over long distances. For digital television enjoyment without interference.
