Installation Instructions
L[G]M[X]M4[X]-6-60[-24-58] Series
SW3-931 – v2

Introduction

The L[G]M[X]M4[X]-6-60[-24-58] series offers a comprehensive range of antennas for vehicular applications requiring 4×4 MiMo function for 4G/5G. The antenna range offers a robust, low profile housing incorporating four ultra-wideband cellular elements supporting 4G and 5G bands, with fall back capability to 3G/2G.
Versions of the antenna are available with additional 2×2, 3×3, 4×4 or 6×6 MiMo function for dual band WiFi and the LG version incorporates an active GNSS antenna suitable for use with GPS, GLONASS, BeiDou, QZSS and Galileo devices.
Please ensure that you have the correct version before you commence installation.

Electrical Safety Note
The LG version of this product contains an active GNSS antenna (part number SR8-JG26NS). Rated voltage: 3-5VDC Rated current: 25mA maximum The supply to this device must be provided with overcurrent protection of 1A maximum.

Mounting Requirements and Selecting Location

This antenna range does not require a ground plane in order to operate, so may be fitted on a metal or plastic roof panel.
When the antenna is to be co-located with other antennas or roof mounted equipment, try to achieve a minimum of 30cm (12″) clearance around the antenna in order to avoid de-tuning and interference issues.
The antenna will fit on a panel up to 9mm (0.35in) thick extender kit M18-EXT is available for thicker panels. For the mounting location, select a flat panel area to accommodate the 18cm (7.1in) diameter footprint of the antenna. For curved or ribbed roof panels, fitting kit LGMM-EXT-R is available as an accessory item. For temporary magnetic fitment the magnetic base SAB-225 is a suitable accessory.

Application Note

The cellular elements in this antenna provide the required isolation for 4×4 MiMo applications.

The use with two separate 2×2 MiMo antenna systems is not recommended as there may not be not sufficient isolation. The antenna could be used where a wireless device has two radios (SIM cards), each with 2×2 MiMo connection, where only one radio will be active at any time (e.g. failover operation).
When used in failover application, ensure that the LTE element pairs are assigned as A&B and C&D.

Where the WiFi antennas are to be used for seperate 2×2 MiMo functions, the same approach to the correctly paired elements should be take n with WiFi pairs assigned 1&2, 3&4 and 5&6 depending on how many elements are required.
Where using 2x 3×3 WiFi using the 6×6 version of the product the antennas should be matched 1,2&5 and 3,4&6 respectively.

Prepare and Drill Hole

Mask the panel area around the hole position to protect the paintwork and headliner. Drill a pilot hole, and then either use a hole cutter of correct size or increase the hole diameter to 19mm (3/4″), ensuring that drill/cutter bit does not contact the internal headliner. Clean area around the hole, carefully removing all swarf. Apply some petroleum jelly or paint around the hole to prevent corrosion.

Fitting the Antenna

Note: The adhesive pad provides a means to fixture the antenna during installation and assists with the sealing function of the antenna to mounting panel. The temperature range for optimum pad bonding process is 21°C (70°F) to 37°C (100°F) – it is recommended that the installation is not carried out in temperatures of less than 50°F (10°C).
Remove the protective backing from the underside of the antenna and feed the coaxial cables through the panel. Position the antenna over the hole ensuring correct orientation and stick the antenna to the panel by applying firm downward pressure.

Caution A slotted/split nut is provided in order to simplify fitting it over the coaxial cables. When fitting the nut, it is important to ensure that the cables are held centrally whilst the nut is correctly started on the threads. The nut should fit freely by hand and only require a final tighten by spanner. Assemble the nut and washer from underside and tighten to recommended torque of 5Nm (3.6 ft/lbs). Ensure that the sealing boot is properly compressed.

Routing and Terminating Coaxial Cable(s)

Connect the extension coaxial cables to the antenna and route the cables to the radio equipment.
When routing the cables take care to avoid running them adjacent to any existing vehicle wiring or fouling any moving vehicle components. The cables must not be routed in front of any airbag device.
Fit the correct coaxial connectors or adapters to the cables as required.

Commission and Test

Check the GNSS cable (if applicable):

Check the GNSS cable with DC to measure high resistance.
Connect the GNSS cable to the GNSS receiver and check for satellite acquisition.

Check the comms cables:

Earth continuity: connector body to vehicle ground should measure <0.2 (where applicable).
Connector body to centre pin should measure open circuit.
Carry out VSWR check – the VSWR on all feeds should meet the specification in product data sheet.
Connect the Cellular/LTE and WiFi cables (if applicable) or secure unused pigtails.

Notices

RF Safety Note Ensure that the antenna is mounted in such a way that no person is likely to be within a distance of 30cms (12″) from the antenna during use. Ensure that the antenna is used only as supplied the co-axial cables should not be cut shorter or otherwise modified.
General Safety Note Make sure that the product is mounted so that it cannot fall and cause injury. Do not chew the product or put it in your mouth. Do not leave children unsupervised with the product or packaging.

European Waste Electronic Equipment Directive 2002/96/EC
Waste electrical products should not be disposed of with household waste. All electronic products with the WEEE logo must be collected and sent to approved operators for safe disposal or recycling. Please recycle where facilities exist. Many electrical/electronic equipment retailers facilitate “Distributor Take-Back scheme”for household WEEE. Check with your Local Authority or electronic retailers for designated collection facilities where WEEE can be disposed of for free.

Directive 2011/65/EU (RoHS 2)
RoHS 2 compliance is declared per Directive 2011/65/EU and its subsequent amendments with exemption 6.c applied.
