I use Cobras at work.
they're pretty damn good, we use 'em in parking lots can do 1 or 2 floors across an entire building
but if there's a body of water in between reception does go down a bit..
this is when working across two buildings with fountain in-between so its pretty rare. i think these
tick all the boxes you're requesting. Yes i've dropped them from atop a 6-10 foot ladder several times :thumbup
they're very much affordable too! :coffee
