My atenna is broken, like most 4th gens now a days. I don't use the radio, so I was deciding to delete the antenna altogether since the sharp remains of the broken antenna has cut me several times. But is there a rubber grommet that fits over the hole for a clean look?

 

Find a cheap eBay antenna and silicone it

 

I had that happened to me, but I replaced it with the new oem antenna that Nissan had at the warehouse at that time. If your willing to take the whole antenna out go in the trunk pass side and try to use a 12mm,14mm bolt take it out of the trunk area and the bolts amount might be around 4 to 3 bolts. If there's any harness attached to the antenna take it out.

 

After replacing the antenna twice it started leaking so I decided to permanently patch it up. From the inside I lined it with fiber cloth, filled with fiber filler then bondo filler on outside, then sprayed primer, basecoat paint, then clearcoat paint. It you don't have a paint gun then fill it up, spray primer then have a body shop paint it. To replace the antenna I ran ribbon cable via the trunk. It had much better reception than the OEM power antenna.

 

Ribbon Cable Antenna? Sounds quite interesting! AND better reception?

Interesting..... VERY Interesting!

 

I pulled the black cover off mine and wrapped the opening with black electrical tape and put the cover back on. It had not leaked and has been working fine of over a year now.
