2.6 External Antenna
Basically, you don’t need external antenna to perform GPS positioning with BT-318 since
it already build-in active antenna. The only condition that you need external antenna is when
BT-318 unit can not “see” the sky, For instance, when you are in any environments that GPS
signal is blocked, the external GPS antenna will help to receive better GPS signal.
Plug the external antenna with MMCX connector to the plug on BT-318. Place the
magnetic external antenna on the roof of the car or an outdoor open-space, and make sure
place it in correct direction. That is, the side with magnetic is the bottom side, and the upper
side must face to sky in order to receive better signal.
