What is the best place for GPS antenna location?
The GPS antenna needs to be located with a good clear 360 degree view of the sky. The ideal location for the antenna is a roof-top. However, in practice the gps ntp server antenna generally works well on a window-ledge or positioned in a window.
As a rule of thumb, the better the view the antenna has of the sky, the better the signal lock and a good continuous uninterrupted time signal.
