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?

These look like the little flying sensor balls from Twister.

Do these come flat packed is that what the tool is for or do you form the whole thing first then use the tool to bend?

Looks like stamped or laser cut pieces that then need bending in the 3rd dimension.
Then soldering a coaxial connector or wire to each half to finish them.

I have no idea if this is a clever bypass around expensive commercial offerings, a clever waste of time that barely improves over doing it by hand, or somewhere in between, but it sure looks like a nice design and print.

It’s an automation step for a small scale factory

Yeah, definite neato factor but by eyeball at least I feel like I could do that bend by hand within a mm tolerance of this. Hard to imagine this precision is needed. Makes sense if mass producing these I guess.

This is a workshop for combat FPV drones, so precision is extremely important.

I make a lot of stuff and I don’t think I could bend it that precisely by hand. Also I would take much much longer.

I think the black thing they show at the end is the usual tool to do it, this just looks like 20 extra needless steps.

It’s for bulk building drones you have into the faces of occupiers, good enough is necessary perfect is not.
