wAP ax - best orientation

I have 2 wAP ax units, which I am planning to put in the loft of my house, which is single storey with a footprint contained within a 21m * 12m rectangle.

My question is what is the best way to orient these?

A single unit located roughly centrally on the short axis and about 5m in on the long axis, stood on a steel filing cabinet in the supplied stand nearly serves the whole house for both 2.4GHz and 5GHz.

I am thinking that as these are designed for wall mount, the signal is probably best in a 270deg disc around the long axis of the unit, so I should aim to orient these facing down and the long axis aligned to the short axis of the house, such that the 2 [imagined?] best signal discs are co-planar on the long axis of the house.

I know this is all guess work and RF often does not work as you might think or hope, but does anyone have any thoughts on this?

Imagine if there was a thing called search

Still dont know why Tik is hiding these details form the procut page…

The beam width is theoretically 180°, but the peaks are in a 90°-120°, so the best possible in a square or rectangle is in two opposite corners.

Aye. And if it could actually reach into people's unrecorded experiences.

Thanks for this. It looks like between this link and @jaclaz 's suggestion I am going to need to make a mounting to hold the unit at a non orthogonal angle.
