Has anybody changed the OEM Antenna and replaced it with a smaller "Whip" Antenna, the kind thats rubber and flexable ?

Sure did. Got it off e-bay. Reception is the same and I like the way it looks much better then the stock one. Look at some of my pics in my signature, I'm sure it will show up in at least one of them.

Should have known it was you Jettech. I saw your truck at United Nissan and thats where i saw the antenna. Thats the exact one im looking for. what is the name brand of it if you remember ?

I just looked on ebay and didn't see any when I typed in Nissan Titan. Sorry TCC but I can't find any nor can I remember who I bought it from. Can anyone else help out here???

Please try and find out that is one mod I definately want to do. Suprised I didn't ever notice that Dale. HMM now I gotta start looking out.
