3.6.3 Connecting to a WWAN antenna

The bintec H2 Automotive+ is equipped with up to eight SMA connectors for WWAN antennas.
Name
MODx 1
MODx 2
The router does not have any internal antennas. Antennas must be installed on the bintec H2 Automotive+ to im-
prove the quality of the signal received and transmitted by the Wireless WAN module (GPRS, UMTS, HSDPA,
HSUPA, HSPA+, LTE, etc.).
The cable used to connect the antennas must be valid for radio frequency (RF) signal communications of up to 2.6
GHz and an impedance of 50 Ohms. Please note that the quality and length (loss) of an antenna cable can affect the
RF signal quality (transmitted and received), which, in turn, will affect device coverage and data exchange rates.
Note
- For optimum performance, always install the WWAN antennas.
- The Wireless WAN interface only works if you have installed the relevant software license.
Each WWAN module has two antenna connectors, labeled 1 (Main) and 2 (Diversity).
Depending on the technology used, you can either use one antenna connector (e.g., for GPRS connection) or both
(e.g., for LTE).
Installing an antenna in the Main (1) connector is mandatory. The second connector ( 2, Diversity) may not need
one. If you are not planning on using the second connector, disable the antenna (through configuration) for optimum
performance.
If you install both the Main and Diversity antennas, they must be at least 7 cm apart. The maximum recommended
distance is 25 cm.
For optimum performance, please use the radio frequency accessories (antennas and cables) recommended by
bintec elmeg GmbH
bintec elmeg GmbH has a range of accessories that allow bintec H2 Automotive+ routers to be installed at different
locations.
