Electronic Project Case: TBS Tuner and Antenna Power Voltage Matching Box

This device adjusts the antenna power voltage of overseas tuners, such as TBS tuners, to match domestic standards (from 18V to approximately 15V).

It connects between the tuner and the antenna via coaxial cable connectors.

Inside, it consists of a diode placed between the connectors (refer to the product photos).
Due to the diode connection, there is a specific orientation for connecting the tuner and antenna.

Please connect the tuner and antenna according to the direction indicated on the diode.

The inside of the case is spacious, so it may be possible to house devices like the USB-connected TBS 5520se. The front cover of the case can be removed.

Thank you for looking.
