Specifications Fully embedded GPS external Antenna Module with RS232/USB/TTL outputs in magnetic mount weather proof casing. Custom wire length Fully embedded GPS external Antenna Module with RS232/USB/TTL outputs in magnetic mount weather proof casing. Custom wire length and outputconnectors can be provided. Cable length can be interested more than the conventional RF cable length as the output of module would be eitherRS232/USB/TTL. The advances are cost effectiveness and Shielding of GPS module as it will be away from main electronics.
