Outside a local school window.
I'm guessing it has to do with networking but I'm curious about why they're outside, especially as they're not that high off the ground and can easily be tampered with from the street.
Stickers on them read "ROCK" and "ROLL".
Antenna for something with flat through window ribbon cables. Modern glass (with e coatings) block lots of signals including mobile data. Just by hanging my 4g mobile router out the window I got from 20-30Mbps down to over 90Mbps !
Not sure on the rock and roll, prob just a bit of fun for the receive and transmit ones.
That seems right, thanks!
I'll mark this as likely solved :)
