Installing Ring Video Doorbell 2

I have a raised porch (6 steps). The existing doorbell connection is about 3 1/2 feet from floor to installation location. The instructions recommend to be installed at 4' from the base of the porch. Since the porch is higher than ground level, do I still need to use the angle bracket? If so, do I place the angle bracket to angle down (because the porch is higher than 4' from the ground) or to angle up (since the existing wiring location is lower than 4' from porch floor)? Hope this makes sense.
