These 9-in-1 antennas contain eight antenna elements. Typically this means one GPS or GNSS antenna element and eight additional element. All of the eight and nine element antennas provide dual-carrier MIMO LTE coverage. This takes up four of the elements, i.e. 2xLTE for each of the carriers. The 9-in-1 antennas typically contain 4xLTE, 4xWiFI and 1xGNSS.
The specific combinations are called out at the product level.
