Thank you for viewing. This is a DX Antenna UHF amplifier, tabletop (for home use) model TU30S(B). My home booster broke, and I urgently purchased and installed this product, but it didn't work with my home wiring, so I didn't use it. I connected the wiring and turned it on once. Please understand that this is a used item as it has been unboxed and used once. Also, there is no flimsy instruction manual. Please refrain from purchasing if you are sensitive to the condition of the product. Returns and claims are not accepted to prevent product substitution. I am also listing this on other sites, so please understand that it may be canceled depending on the timing.
