Installation InstructionsGPS[2]5 SeriesSW3-1035 - v31. IntroductionThe GPS[2]5 antenna series is a range of high-performance L1/L2/L5 and L1/L5 band GPS/GNSS antennas with excellent filtering. The antenna module ishoused within a low profile, robust enclosure and is suitable for use with GPS, GLONASS, Galileo and BeiDou systems requiring high accuracy for naviga-tion, RTK and other precision applications.The antenna is available in panel mount (GPS[2]5P) and magnetic / adhesive mount (GPS[2]5MS) variants. The GPS[2]5P can be installed on a metal orplastic panel. The GPS[2]5MS can be attached by magnetic adhesion on a ferromagnetic panel. For other mounting surface materials, the adhesive padcan be used.The antenna is supplied with integral flame retardant RG174 cable (compliant to UN ECE R118), and is suitable for many installation environments.2. Mounting requirements and selecting locationThe antenna should be mounted with a clear view of the sky for optimal satellite acquisition.If utilising the adhesive pad it is recommended that the installation is carried out when the temperature is higher than 50°F (10°C) - the ideal temperature forthe pad bonding is in the range of 70°F (21°C) to 100°F (37°C).For the panel mount version, ensure that there is adequate under panel clearance and that there is no double skin panel or cross brace present.Measure to check for central position if applicable.For optimal performance the antenna should, if possible, be mounted at least 300mm (1ft) away from other conductive objects on the mounting panel.3. Panel MountingMask panel area around hole position to protect paintwork and headliner. Drill a pilot hole, and then increase to 19mm(3/4”), ensuring that drill/ cutter bit does not contact headliner. Clean area around the hole, carefully removing all swarf.Apply some petroleum jelly or paint around the hole to prevent corrosion if necessary.Remove protective backing from underside of antenna and feed coaxial cable through panel. Position the antenna over thehole and stick to panel by applying firm downward pressure. Assemble washer & nut from underside and tighten.IMPORTANT: Do not exceed a torque of 5Nm (3.6ft/lbs) when tightening the mounting nut.Hole∅194. Adhesive MountingMake sure that the selected mounting surface is clean and dry. De-grease suface with 70% isopropyl alcohol (allowing time to dry) if required. Themagnetic / adhesive version of the antenna is supplied with an anti-scratch pad fitted as standard and this should be removed before the adhesive pad isfitted to the antenna. Once the anti-scratch pad has been peeled off, remove protective backing from supplied adhesive pad and adhere to underside ofantenna, position the antenna over desired location, remove remaining protective backing and stick to panel by applying firm downward pressure.This product contains an active GPS/GNSS antenna.GPS25 part numbers contain an L1/L2/L5 GPS/GNSS antenna: Rated voltage: 3-12VDC Rated current: 35mA maximumGPS5 part numbers contain an L1/L5 GPS/GNSS antenna: Rated voltage: 3-5VDC Rated current: 37mA maximumThe supply to these devices must be provided with overcurrent protection of 1A maximum.
