Connecting The Wlan Antenna; Connecting The Gps Antenna; Configuration Connection - Teldat H2 RAIL Installation Manual

3 Components and power supply
The following recommendations are applicable to all wireless devices:
• Do not touch or move the antenna while the device is transmitting or receiving.
• Do not touch any equipment containing radiating devices if the antenna is very close to, or touching, any part of the
body (particularly the face and eyes) and is transmitting.
• Do not install the device in areas where the atmosphere is potentially explosive.
• Wireless devices can cause interference in other devices. Do not use them in areas where medical equipment is
installed.

3.5.3 Connecting the WLAN antenna

The Teldat H2 RAIL is equipped with type N connectors to connect up to two WLAN (Wi-Fi) antennas (on models
equipped with this interface).
Since the router doesn't have any internal antennas, external antennas must be installed on the Teldat H2 RAIL to
improve WLAN signal quality.
The cable used to connect the antennas must be valid for RF signal communications of up to 2.4 GHz (5.7 GHz for
802.11a) frequencies and impedances of 50 Ohm. Please note, the quality and length of an antenna cable can affect
the quality of RF signals transmitted and received. This, in turn, will affect the device coverage and data exchange
rates.
Please note an appropriate software license must be installed for the WWAN interface to work.
The following image shows the location of the WLAN antenna connectors (MOD3 and MOD4).

3.5.4 Connecting the GPS antenna

The Teldat H2 RAIL has an FME connector to connect an active GPS antenna (on models equipped with this inter-
face).
Since the router doesn't have any internal antennas, an active 3.3V external antenna must be installed on the Teldat
H2 RAIL to optimize the GPS signal quality.
The cable used to connect the antennas must be valid for radio frequency (RF) signal communications of up to 1.5
GHz frequencies and impedances of 50 Ohm. Please note the quality and length of an antenna cable can affect the
quality of the RF signals transmitted and received. This, in turn, will affect the device coverage and data exchange
rates.
The following image shows the location of the GPS antenna connector.
