Well only because I am thinking about a Sharkfin with GPS, FM and DAB. But I thought it would need the metal roof for a ground plane?
And I thought all of the roofs including the aerodynamic wedges that some roofs have are not metal?
It’s important to me because ai haven’t had the roof done on my T6 yet. But I want the sharkfin. And if it works with the roof in that picture. Then that’s the roof for me! Except I don’t know what roof it is?
