Thank you very much for viewing my listing from among many others. This time, I am offering a Nippon Antenna indoor UHF booster VB-33MU. The amplification gain is 25-33dB for UHF. It has a power supply function for BS/CS parabolic antenna converters, but it does not have an amplification function for those signals. The main unit is a tabletop type, so you can simply place it near your TV to receive a good picture. Unfortunately, there is no instruction manual or outer box. Thank you for your consideration.
