Mitsubishi RF Converter Unit for Video with RF DC Output Terminal DAR-X1 Specifications: RF Converter Unit Power Supply: DC5V 20mA (Supplied from video) External Dimensions: Width 50 x Height 65 x Thickness 35mm Cable Length: 1.5m Weight: Approximately 110g Instruction manual is also included. I think I bought this to connect an old TV and a VCR. I haven't used it for a long time since removing the RF converter, so I haven't confirmed whether it works properly. I am not familiar with this item, so I may not be able to answer questions. The price is the final price.
