CS/BS-IF UHF Booster

The TV screen started showing blocky noise, so I tried replacing the booster.
I purchased this on Amazon on March 3, 2025, for 8,000 yen, but it didn't fit my home, so I'm selling it.
It seems my home required a 30db booster, and nothing was displayed. Please be aware.

Model Number: TCU15L1
DX ANTENNA CO., LTD.
15db type

Thank you.
