These mains hum eliminators, commonly known as 'humbuckers' are inherently transparent to a video signal, causing minimal differential phase or gain distortion. They do not block DC control signals and feeds. Built in die-cast aluminium enclosures with mounting flanges, they have two recessed female BNC connectors.
If the application also requires protection from the effects of variation in ground potential, such as operator shock or equipment damage, or the removal of more severe distortion, then see LEN VIDEO ISOLATION TRANSFORMERS - Analogue or see LEN VIDEO FILTERS - SD, HD, 3G, 4K/12G SDI ground isolation.
