DAB+ reception with original antenna/amplifier?

Hi, my 350z is a GT pack from 2003 and I've replaced the Bose head unit with a Pioneer one. I don't want to put a DAB aerial in the front windscreen and am wondering what others have done for their DAB reception?

There are spiltters on the market to connect between OEM antennas and the head unit but the 350z has an antenna amplifier as well. Does anybody know if the amplifier filters out the higher frequencies for DAB?

Has anyone tried a tried a DAB whip antenna with the amplifier?

 

Cheers,

Jerry

I'm looking for new options as the original dab antenna i didn't like the look of but it worked. Next was a discreet one at the top of the screen but reception isn't good enough.

Spoke to a company yesterday and they suggested one that hides either behind the front bumper or under the wiper scuttle? But at £100 just for the kit I'm still thinking about it....

Also mine's a roadster so I'm limited where it can go....

Well I've just finished fixing my DAB reception a few minutes ago.

What I had before was an antenna for the top of the windscreen which was earthed and laid flat under the 3 center instruments, trouble was the reception dropped out more often than not, so it wasn't good enough. So this is what I've just done:
I replaced the original whip with a shorter DAB type.

The little antenna amplifier at the rear filters out the higher DAB frequencies so I had to connect the original antenna lead to a DIN plug to go to the antenna.

At the head unit end I've connected the antenna DIN plug to a DAB antenna splitter, which has 2 connectors to the head unit for both DAB and FM.

The splitter needs power and earth so it gets power from the same cable that goes to the amplifier (I had the Bose system). The earth is connect to one of the screws below the satnav screen.

The results are great now so I'm really very happy with this.

I've looked at a few pics of 350z roadsters and they look like they have the same antenna as the coupe so you can probably do something similar to me?
