RetroSound HPA1 アンプ内蔵隠しアンテナ クラシックカーラジオ FM AMアンテナ

Wasn't sure an amplified antenna would pull in anything decent in my area, but AM comes through clear now even with the unit tucked away out of sight. The small size made it easy to mount where nothing shows.

It tucks away so neatly that you’d never know there’s an antenna on the car, and the small size made mounting it behind the dash a total breeze. FM reception is just as clear as my old fender unit, which honestly surprised me.

The small size was a lifesaver for hiding it under my dash without any visible mounting hassle. Took a bit to get the FM stations clear in my area, but the AM reception is surprisingly solid for such a compact unit.
