Installation Instruction – SW3-683
GPSC Series
Introduction
A.
The GPSC Series is a line of internal mount LTE/Cellular, and GPS/
GNSS Antennas. The standard GPS/GNSS LNA gain is 26dB.
SW3-683 - Document Version 1.0
Electrical Safety Note
This product contains an active GPS/GNSS antenna (part number SR8-HG26-04FJ). Rated voltage:
3-5VDC Rated current: 20mA maximum
The supply to this device must be provided with overcurrent protection of 1A maximum.
Mounting requirements and selecting location
B.
The GPSC antenna is designed to be fitted on or under a vehicle dashboard, located as far forward as possible
to optimise view to the sky. When fitting under the panel, a position should be selected to ensure there is no
metal close to the antenna inside the panel.
The optimum orientation for the antenna is to be fitted flat and the UP side must be facing towards the sky.
It can also fitted on or under any other non-metallic panel in a position that allows an adequate view of the sky
to enable satellite acquisition.
The antenna can be fitted to a vehicle window, but it is important to note that GPS/GNSS performance will be
reduced on a window that has a small angle of incline or is vertical. The UP side must be facing the outside of
the window.
Note that the antenna should not be fitted to a fine wire mesh type heated window or heat reflective type glass
The antenna location should ensure that the front curved face of the antenna is a minimum 10cm (2”) away from
any metal structure.
The antenna must not be fitted adjacent to or in near proximity of one of the vehicle electronic control units
(ECU).
Mounting the antenna
C.
Note: It is recommended that the installation is not carried out if the temperature is less than 50°F (10°C) as the
ideal temperature for the pad bonding is 70°F (21°C)to 100°F (37°C).
Before fitting, ensure that both the antenna face and mounting surface are clean and free of grease – use the
supplied alcohol swab and allow the cleaned surfaces to dry before proceeding to fit the adhesive pad.
Remove the protective backing from the adhesive pad, place on correct face of the antenna, to enable the UP
side to face the sky and apply adequate pressure to adhere.
Remove the protective backing from the antenna pad, position the antenna and apply adequate pressure to
ensure that it has adhered correctly.
