The Bosch Autofun
antenna as it is quite affordable $40-$55 at local auto accessories
shop c/w installation.
The Bosch Autofun antennas are sleek, unintrusive and fuss-free.
This antenna is placed on the inner surfaces of the vehicle
windscreen. As a result, it is not exposed to the elements such as
wind, rain, and dust, unlike antennas located outside the vehicle.
The Autofun antenna is maintenance and dust free. Autofun antennas
also come with a booster to improve reception.
Used the Bosch Autofun on my previous rides from cars, pickup and
vans and it works great everytime.
