Hello together Unfortunately I found nothing specific about the topic (where with the antenna ). I have an Audi Q2 without Dab Radio. I bought a kit and built everything ( works together with the Oem Radio ) in the glove compartment. Fm Radio continues to work. I choose from the menu Aux, I get the pleasure of Dab. So it seems to work. Unfortunately, what is not so good is the reception, it often interrupts even with small underpasses ect… Since the driving fence g no dab had, an antenna was supplied number is 81A035225D. I have installed it currently near the A column (fixed ) not screwed like OEM. Original has the car at the tailgate top 2 such antennas, left and right. They are identical as the above mentioned (new antenna ). I would like to know, wiso has it original 2 antennas? The right still has a small output with cable which go to the rear window. The new antenna dab would have an output from such an output. Me in question must/can I now expand an old antenna ( FM) and screw the new Dab antenna there? The design is indeed identical and could I bolt there immediately. As a result I would only have an Fm antenna. Does it matter if I mount the new antenna to the right with connection to the rear window? Or better replace the left? Option 3 mount the new antenna in addition to the 2 existing antennas, stop with cable tie ect..? I am also uncertain if by the Sch rob which all 3 antennas have to attach to them a kind of necessary grounding takes place. Does everything sound wild but it is only about which of the 2 existing locations/antennas I can replace or I should let everything exist and the Dab antenna additionally somehow lock back there. PS: FM reception would not be so important after that Many thanks in advance example picture below at the marked points are the 2 original antennas installed optically / identical to the new Dab antenna
