Digital Radio (DAB) & AM/FM Active Splitter & Amplifier
This will only work on passive antenna systems
Simply plug inline with your head unit aerial connection and then plug the DAB plug into the DAB socket on the back of the headunit.
Connect the Red wire to the aerial power lead that is 12 volts with the radio switched on.
No need to install an additional DAB Antenna when installing an aftermarket DAB Tuner.
