I liked KC3RE’s VHF rover enough, I went looking for other interesting car radio installations. There’s quite a few!
This Ford Escort has a pretty inconspicuous setup.
This isn’t the same vehicle, but it might be similar:
Radio operator KC8HZM put a small antenna on of his Festiva.
AB7FH has a large antenna belonging to N0LRJ’s “Radio Active Samurai”.
This Toyota Sienna van makes me think my own Honda Odyssey would look better with some large antennas on top of it.
Enthusiast site “Hamsexy” has quite a few good antennas mounted on trucks, including a pretty clean looking Chevy Avalanche setup.
It would definitely be eye catching to see one of these rolling down the street.
