I use this combo that works well.

This on two other cameras where I don't have the room to run cables.

That will only work for analog cameras.
As I said, I need an outdoor camera.
I prefer 5GHz for least interferences of signals and because I use another device that works in 5GHz band. Of course, if I use an IP camera, I would prefer one with ethernet connectivity and not analog connectivity.
More suggestions would be appreciated
