Unfortunately, this antenna does not work with my Kenwood car stereo

While it is in the heading / title of the antenna

"Kenwood DAB antenna CX-DAB1 disc mount antenna for all DAB / DAB + devices with SMB connector"

but for me it does not go. I can exchange it no longer since I was a little abfeilte the plug of the antenna, so that he gets better contact.
Unfortunately, that did not work well.
Furthermore, the antenna looks I did not get the same as in the photo, there is in fact an original image of the Kenwood antenna supplied with the car radio.
The plug and the adhesive antenna itself, look different.
