While in Concord for the ISSCA Nationals, I did see a G8 with such an antenna--unfortunately I did not get a picture of it or talk to the vehicle owner.
Today, I spoke with the owner and he was able to tell me that the unit he used was from an online seller called Visual Garage - website is not currently functioning http://www.visualgarage.com/home.html" onclick="window.open(this.href);return false; , other than to collect e-mail addresses, but (as posted in another thread), there are several sources, offering different levels of price and features.

E-bay has numerous knock-offs, too.Navy Lifer wrote:Can anyone take this further? How can we determine which antenna performs which functions(s)?
Looking at a "shark fin" option--anyone have the inside scoop on doing this?:

Just picked a couple of sites and did some looking--no idea what may or may not actually work.
There is a thread on the G8 Board, too: http://www.g8board.com/forums/showthread.php?t=9665" onclick="window.open(this.href);return false;
The G8 owner indicated that it did cause his OnStar to not be able to function--but considering the PPV doesn't have OnStar, that's largely a non-issue.
Many new factory vehicles, including new Chevys (2014 Impala, Malibu, Camaro, etc)--as well as the WM Holden/Buick Park Avenue in China--are now using a "fin" to mount antennas, primarily for satellite connectivity, it appears. If anyone knows more about this, please chime in, as I think there is probably some interest in our group for a good and correct way to do this.
