Not yet, no, but there is no doubt it would work. If you replace an omni antenna with a directional antenna and aim it correctly, you will get better range. You just have to figure out how to mount it.
I'm just not sure, because the SE controller has 3 antennas. One omni, a two other inside the controller. As far I know P3S has only one. And I haven't fund jet information, if the function of three antennas are the same, or different.
