■ This Maspro TV booster "UTR30BC" is a device used to amplify (strengthen) the radio wave level of TV signals received by the antenna when the radio waves become weak. ■ This is a USB-connected booster to enhance UHF signals, with a UHF gain adjustment knob and three output terminals. ■ Operation has been confirmed, and it comes with a reassuring instruction manual. 【Product Specifications】 - Model: UTR30BC - Type: UHF Booster - Power: USB connection to adapter - UHF Gain: Adjustable function - Output Terminals: 3 output terminals ※ UHF/BS/CS mixed input available - LED Indicator: Green LED indicator - ⚫️Included items: All items are shown in the photos. 【Condition】 ■ Although it was connected to a TV, I was using a different indoor antenna, so I haven't used this one for many years, so it's clean and I think it can still be used. The condition of the item itself is very clean and good as I haven't touched it much. It's a beautiful item. However, it is not new, and there may be oversights, so I will rate it as "No noticeable scratches or stains". I haven't used it at all for the past 5-6 years or more, so I think the lifespan of the device is long. If you are a clean freak or are concerned about the condition, please feel free to ask questions. 【Shipping】 ■ The item will be wrapped in bubble wrap, placed in an OPP bag for waterproofing, and then placed in a shipping box, with paper filling the gaps to prevent movement. And it will be shipped via the anonymous shipping service of Rakuraku Mercari, so you can rest assured. 【Other】 ◆ If there are any defects in the product, please let me know before rating.
