These 2-in-1 antennas contain two antenna elements. Typically this means one GPS or GNSS antenna element and one additional element such as WiFi.
In some cases, a customer specifies an antenna without a Global Navigation element. In those case the model number will often retain the model number as if the GPS/GNSS element were included and the model number will contain “00” in the cable/connector section to indicate the absence of the GPS/GNSS elements. (If this sounds confusing, and it is, give us a call and we will make sure the model number ordered matches your network requirements.)
