I had bought a car (Opel Combo C) without radio and without antenna So I had to build everything ... I bought the antenna. Unpacked .. So nothing special noticed. Connecting lines are very very long .. So you can lay the line almost everywhere ... MW / DAB + and 12V power supply. The cables laid through the A pillar and clamped With the radio "Pioneer DEH-X5900BT" I could only test the MW. Unfortunately, DAB + does not have it. BUT: I got the transmitter in, I did not know it yet. The days I will test it on the track ... The antenna is great to recommend ... I would buy it again anytime * thumps up *
