Personal DAB - Adding External Aerial (Modding It!)

[crocket]

Hello!!

I'm trying to add this DAB unit into my car as it's really small and would fit where I wanted it to fit exactly.

The signal will be poor on the move, so I have installed a blaupunkt DAB aerial to my car which provides a coax which I can connect to my DAB unit.

The unit I have bought is this...

**broken link removed**

It get's the signal from the earphones somehow, probabily using the shielding.

It's a standard 3.5mm jack (standard 3 pole)

Which pole(s) do I attach the DAB aerial to get it to work correctly?

Hope you can help!

After doing some research, do I connect the middle of the aerial coax connector to the ground (outer pole) on the headphone socket?
