4K/8K compatible tabletop booster, easy to install with its minimal size. - Model: NAVBC22UE-BP - Function: 4K/8K compatible tabletop booster - Frequency Band: 322MHz - Power Supply: Includes 1 AC adapter - Connection Terminals: 1 input terminal - Size: Smallest tabletop size Thank you for viewing. I purchased this at a mass retailer in Kagoshima. I bought it for home use, but it doesn't work with my setup, so I'm selling it. 【Size】Length: 19cm, Width: 7cm, Thickness: 4cm 【Condition】It's almost new, having only been powered on a few times! The case is also in the same condition as when I bought it, with no scratches! I don't know much about boosters, so please check the photos for details. I cannot answer questions about the functionality. m(__)m Thank you.
