2.3.  External Antenna 

Basically, you don’t need external antenna to perform GPS positioning with BC-337; it already has a 

built-in antenna. The only condition that you need external antenna is when BC-337 unit can not “see” 

the sky, For instance, when you are in a car, or any environment 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 BC-337. Place the magnetic external 

antenna on the roof of the car or the outdoor open-space, and make sure not to put it upside down. 

That is, the magnetic side is the bottom side, and the upper side must face to the sky in order to 

receive better signal.
