Installation

Installing a Remote Antenna

If the WirelessHART gateway is mounted indoors, or if there are many metal obstacles in the 

immediate surroundings, you can also connect a remote antenna to the WirelessHART 

gateway. Note that the use of a different antenna or the use of an antenna with a different 

antenna gain is subject to legal restrictions.
