Can AP8150DN be connected to a power splitter to access a new antenna

Hi friend!
It is not recommended to use it this way, but you can try it because there is no such solution in the official and information. This is not a standard solution.
AP8150DN has 2 2.4G/5G shared antenna interfaces and 2 5G antenna interfaces.

You can also use AirEngine8760R-X1E with 8 2.4G/5G shared antenna interfaces. Antenna interface type: N-type female (threaded on the outside and tube in the center), and antenna or feeder interface type connected to it: N-type male ( There is a thread inside and a needle in the center).

Hope to help you!
