Found in the closet! DX Antenna UHF Booster BU433D1 33dB/43dB For sale. Stored in a dark closet. My aunt's apartment only had poor reception for TV Asahi, so I bought this at Komeri, but I opened it and didn't know how to use it, so I put it away. (In the end, the poor reception was due to a faulty antenna) If you know how to use it, please do. Please check the condition in the photos. The instruction manual is missing, so I will include a downloaded copy from the HP. Instant purchase OK. Will ship via anonymous Mercari shipping. Negotiations for price reduction in the comment section are not allowed. Please feel free to contact me if you have any questions. UHF booster BU433D1 is a 33dB and 43dB shared type, compatible with 710MHz frequency. - Model: BU433D1 - UHF Booster: 33dB / 43dB shared type - Frequency: UHF 710 MHz Thank you for viewing.
