This antenna features a modern looking 8" antenna mast which is constructed from 6061-T6 billet aluminum. The antenna will only work with Mustangs equipped with a round antenna base mount. The round base mount is powder coated in a clear anodized finish allowing it to withstand the outdoor elements. You must reuse the original wedge from the stock antenna or it can be purchased separately under part # C5ZZ-18A915-A if needed.
