The Jensen Transformers
ISO-MAX VBH-1BB is a single-channel, studio-quality, high-bandwidth ground loop isolator that can reduce ground current-induced interference, such as "hum bars" by a factor of over 100, while also reducing audio hum or buzz in connected audio systems.

With bandwidth that extends from DC to 900 MHz and super-low 0.05 dB insertion loss, you can expect excellent picture quality, free of the visible effects of video interference.

Inputs and outputs feature isolated, true 75 Ohm BNC connectors.  The VBH-1BB is housed in a sturdy metal enclosure, measuring 3" W x 4.5" D x 2" H.
