What am I looking at here? What are these antennae used for?
They're popular with drone pilots, here's some old school website about them
I'm not a radio guy, but for a drone antennae, wouldn't you want vertical range rather than broadside range?
No, yagi directionals point at the drone broadside.
A drone operator usually is not standing directly under the drone, so no. Or alternately, the drone if probably further away from you horizontally than vertically during most of its operation.
One interesting thing here is that, for a given altitude, the antenna gain will be higher the further away the drone is.
Here's the only thing you need to know: radio is black magic.
