So I was leaving my sisters house this evening and noticed that the tip of my antenna on my '03 CLK 500 is missing. Could this have simply fallen off or is it more likely someone took it?

Either way, I need to get a replacement, but I am not exactly a genius when it comes to cars. I tried doing a search for "antenna" but apparently, this year no longer uses an antenna? Does anyone have a part number or official name for this item? Thanks in advance for your help, you have no idea how much any help is appreciated.

Hoping I won't have to pay a finger to afford this item,
