I had ordered a DAB + car radio from Sony, which mitlieferte a disc mount antenna. The reception this was very changeable, partly full reception, some none at all. And although I between 2 transmitters Pendele (Rheinturm and Colonius). Even only 100m air line between me and the Rheinturm there were receiving dropouts. I decided to order this splitter because my car roof antenna has a passive FM. The splitter is surprisingly small and can be in 5 minutes install. However, one should note that it must be powered. The problem was solved here emanating from the radio control voltage to the power amplifier. The splitter works perfectly! Now I have no more dropouts. Yes even in short tunnels is DAB reception available. By the way, even the FM reception has improved significantly! The price appears vll. A little high, but the splitter is worth every euro! Clear recommendation, clear 5 stars
