This is more or less an upcoming mod but I wanted to put this out here just incase someone else tried it and has some tips and/or input...
I'll be installing a Siruis tuner later this month and want to hide the Sirius antenna with a shark fin cover. I started my search for such a cover on EBay and bought this:
EBay Shark Fin
It was only $9.00 which included shipping from China so I figured it would be no big loss even if sliver lead paint was used on the fin

or if it was a total POS. Eight days later this arrived:
I can best describe the quality as OK...and pretty much what I expected for the $9.00...
I put it on the car and wasn't really digging the antenna's shape and silver paint...keep in ming that that gaps you see are because the fin is not attached...it's just laying in the roof.
Since I still want to cover the Sirius antenna with a shark fin I search some more and found this:
VG Shark Fin Antenna
This is a functioning antenna which is marketed toward vehicles with roof top antennas as a replacement and some of the users also use it also to cover their satellite antennas.
I like the shape for the VG Shark Fin and probably the best part is that it will be custom painted to match the car colour.
Anyone do something similar?
