BMW have a sharkfin antenna, and out of this, there have been made many replicas
GPS/WiFi/Radio is probably the most common one.
There are so many antennas connected to my car pc, GPS/Phone/Radio/TV...etc, is it possible to make a all-in-one antenna?
The only antenna I actually have outside my car is XM, that dropped out too much when inside the car.
I have that 3 mode antenna from the store, and is seems to work just fine. I don't currently use it for WiFi (though did in my last install), but I use the GPS and Cell connections with my GPS and EVDO USB modem, and both work great, at the same time. I actually currently have it on top of my dash (haven't gotten the nerve to drill in the roof yet), and I get great reception on both.
