Adding a DAB/DAB+ aerial – DIY is useful if you haven’t decided how to add on DAB/DAB+ support to your vehicle.
See the main article to see the other options – Adding a DAB/DAB+ aerial to the Volkswagen Golf Mark V & VI, Jetta, Passat and others The connector on the rear of the head unit is a Fakra Black Type A plug so a Fakra Black Type A jack (or a universal one) is required on the DIY aerial, see the this article for further information on Fakra connectors – FAKRA (SMB) Connector Information and Specifications.
In this example I’ve used a spare RNS 510 GPS aerial with RJ174 coax, cut off the GPS aerial and removed the Fakra Blue Type C jack housing from around the connector.
Construction is simple.
1. Strip away the outer insulation and the braided shield from the first 300mm.
2. Strip away the outer insulation on the next 230mm.
3. Make a coil after the braided section of 50mm in diameter and secure with some electrical tape or similar.
4. Add electrical tape or heatshrink to the end of the braided section as shown and the end of the aerial to enable it to be hung up.
This aerial is best suited to a static environment such as a house but works quite well in a vehicle in various locations such as behind the front seats and the b-pillars.
