Baseband-composite video isolator with BNC connectors. When inserted into standard 75 ohms video cabling, this transformer based isolator eliminates video hum bars, as well as the often associated audio hum or buzz in multimedia entertainment systems, by breaking the so-called ground loop. Mounting holes allow easy horizontal or vertical mounting to standard rack rails.
