I think he means hidden antennae, not a power antennae. wanting a smooth fender, no antennae at all look. From what I have seen the ones built into the windshield work tyhe best without having a metal pole sticking up, but we don't have any cars we can steal that type of windshield from to fit our E bodies. The stick on ones that work are pretty ugly and defeat the purpose. I do see more and more people getting rid of their radio alltogether and just having an Ipod jack instead or the smaller XM antennae. That way you clean up the inside and outside. maybe an antennae mounted in the trunk under the package tray? That would allow it to be long enough to be effective and not be seen.
