This cover is made of aluminum and not cheap ABS plastic. The hardest part is removing the OEM antenna base cover without destroying it. Basically YouTube those exact words and you will see a video that only requires you to use a tiny screwdriver. The only thing I had to modify was the gasket, I had to cut it to put t behind the actual antenna base, you will see at I'm talking about when you take it off. Simple install that took me about 10 minutes. Hope this helps.....enjoy and happy jeeping!
