Anyone know how directional the antennae you get on #Wifi access points actually are? My #Openwrt One has 3, and I don't know if I should be worrying about which direction they point in...?

@demoographics I've got two antennae. I read what I could find and it said "point one of the horizontal, the other vertical" and that seems to work better than other random things I'd tried. I don't know how that might translate to three though.

@demoographics generally speaking you can treat them as having strongest output "broadside" to the antenna, perpendicular to the antenna's longest side based on the general antenna type.

You can think of the radiation pattern as a doughnut shape in 3d, with the holes being "up and down" where the tip of the antenna is (weakest above the antenna where the tip is pointing).

(So not very directional but should have a shape to it)

@demoographics for the question about orientation if you're using MIMO ensure they're pointed the same way. Some people put them vertical and horizontal to handle differently oriented / polarized signals and coverage (nothing but a good thing there), but that increasingly works less well as we get into newer wifi protocols using space time coding etc

@paul Thanks. That suggests that vaguely pointing them at bits of the house that had poor coverage from the previous AP that I'm replacing is exactly the wrong thing to do :blobfoxfacepalm:

@demoographics pesky rf being invisible and mostly inscrutable magic mirire 😂😭

Hope that helps debugging, good luck! It's mostly just guess and check realistically, hope it's smooth sailing!
