- For interference-free DVB-T reception - Solid full metal housing for protection against outside interference - Fully shielded lines for optimal reduction of electromagnetic interference - Reduces interference from the field of GSM, LTE and DECT for DVB-T reception - Connection between a receiver and a DVB-T antenna - The best result is achieved if the filter is directly connected to the receiver input as interference caused by poorly shielded coaxial connection cables is suppressed before
