Review: Picks Up GPS Quickly - I bought this GPS antenna to replace my failing cheap Chinese poop antenna fitted with the vehicle head unit and was surprised by the results. The base is magnetic to allow the GPS antenna to be mounted on the outside of the vehicle, although I have magnetically stuck it on the inside of the van roof and it picks up the GPS almost instantly. The old antenna took several seconds and gave up if not found before starting the journey. This GPS antenna is also amplified to provide a stronger signal to the sat nav but obviously you still need to be within the range of GPS signals. Amplification doesn't overcome a poor GPS reception area. Generally, I am impressed by the performance of this device for the money and would definitely recommend. Downside, it comes from the States so potentially takes 2+ weeks for delivery.
Review: Excellent GPS reception - Providing clear GPS signals for an AIS system inside my steel boat with the receiver sheltered under a solar panel. Ideal low cost solution!
