Panorama Antennas SW3-875 LGMQM4 Series Installation Instruction

Installation Instruction – SW3-875
LGMQM4 Series
A.
Introduction
The LGMQM4 antenna series comprises a range of vehicle
antennas for new generation devices that require 4x4 MiMo
function for 4G/LTE. The rugged, low profile housing incorporates
four ultra-wideband cellular elements for frequency range 698-
960MHz and 1710-3800MHz. Versions of the antenna can in
addition provide 2x2, 3x3 or 4x4 MiMo function for dual band
WiFi and also an active 26dB gain GNSS antenna module.

Application Note
The cellular elements in this antenna provide the required
isolation for 4x4 MiMo applications. The use with two
separate 2x2 MiMo antenna systems is not recommend-
ed as there may not be not sufficient isolation. The an-
tenna could be used where a wireless device has two ra-
dios (SIM cards), each with 2x2 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
2x2 MiMo functions, the same approach to the correctly
paired elements should be taken.
Electrical Safety Note
The LG version of this product contains an active 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.
