Know before you buy
By mounting the antenna to the exterior of your vehicle, you elevate it above the metal roof, which typically blocks or interferes with GPS signals. This positioning provides a clearer line of sight for your handheld device, resulting in a more consistent and extended tracking range.

Yes, the magnetic base is specifically engineered for vehicle use and is strong enough to remain securely attached to your car's roof or hood during standard driving conditions. However, it is always a good practice to ensure the mounting surface is clean and flat for the best possible hold.
