Horizontal vs Vertical Mounting AP6 PRO

My current cabling setup would require mounting on a wall instead of ceiling, would this be detrimental to signal quality and range? If so, how noticeable would it be?

i justed hanged one horizontal because it just looks nicer. I will add the picture here, so you can see the difference. Mollie’s setup with Alta, Mancave next? - #5 by Alta-Dallin
It looks better but range in the Horizontal is less. I might be bacuse of my situation but look at it so you can compare

The antenna patterns are similar horizontal vs vertical. It really shouldn’t matter, but if you have data would like to see signal strength if you switch it?

Hi MattH i answered here when i changed to vertical position for the data as you asked.

So there is some difference as you can see.
Best regards,
Mollie
