Installation Instructions – SW3-689 GPSD Series Introduction A. The GPSD series is a high performance multi-function shark fi n OEM style antenna with 2x2 MiMo for 4G/LTE. It incorporates an active GPS /GNSS antenna with 26dB gain LNA and there is a version that also includes 2x2 MIMo dual band WiFi antennas. In addition, a mounting stud is fi tted, to allow a range of antenna whips to be used. The GPSD is suitable for fi tment to vehicle panels of up to 3mm (0.12”) or 8mm (0.31”) depending on which type of earthing washer is selected. (see section D). Heat shrink tubes are included in the kit, to enable the coaxial connections to be sealed as an extra precaution if required. SW3-689 - Document Version 2.2 For optimum performance it is recommended to fi t the antenna on a conductive (metal) panel, but if a whip is not going to be fi tted, then the antenna can be mounted on a non-conductive surface and still provide acceptable performance across all functions. If a whip will be used, then the antenna must be fi tted on a conductive ground plane - recommended size is minimum ½ wavelength diameter at the lowest frequency of whip operation. To calculate required size see below: 150 / frequency in MHz = ½ wavelength (m) Examples: 150MHz =100cm (39.4”); 400MHz = 38cm (15”); 900MHz =16cms (6.3”). When fi tting on a non-metallic panel, a ground plane plate of suitable size should be fabricated and fi tted under the mounting panel; the earthing washer must make low resistance electrical contact with this plate (<0.2Ω).Select a mounting location, checking for roof curvature to ensure that the antenna base will have a fl at mounting surface. The antenna should be located as far as possible from surrounding roof mounted items (e.g light bar, air con unit). 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. Mask 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. Remove paint and primer from under panel surface to ensure adequate earth contact by washer and nut. Apply some petroleum jelly or paint around the hole to prevent corrosion. Hole ∅19 Electrical Safety Note This product contains an active GPS/GNSS antenna (part number SR8-HG26). 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. Prepare and drill hole C. Fig.1 Important Note Regarding Sealing In order to ensure that the installation is properly sealed against the mounting surface care must be taken regarding curvature of the mounting panel. It is highly recommended to install the antenna on a clean, fl at and level surface. After installation the compression of the rubber boot against the mounting panel should be checked and a small bead of neutral cure silicone sealant can be apprlied around the periphery of the mounting boot if requried. Fitting the antenna D. Remove protective backing from underside of antenna, feed coaxial cables through panel. Position the antenna over the hole ensuring correct orientation and stick to panel by applying fi rm downward pressure. It may be advisable to apply a very small amount of neutral cure silicone sealant around the base of the mounting boot to overcome friction and allow the boot to fully compress against the mounting panel
