I think they're uglier than cell towers. They look like what they are- fake trees trying to blend in with real trees and doing it badly. That's worse than simply putting up a metal and concrete tower to me.
I live in LA and to be fair, palm trees are basically fake trees in the first place, they're mostly non-native Q-Tips that give no shade. The cell towers should just cover themselves with billboards, they'd fit right in and make extra cash from the side hustle.
I'm not a fan of the palm trees either, but a perfectly straight pole with fake leaves that do basically nothing to hide the fact that it's a cell tower was even worse to my eyes.
The craziest thing about billboards when I was in L.A. was the trucks driving around with billboards on them that were only being driven around because of those billboards. I guess the cost of a truck and fuel is still cheaper than paying for an actual billboard on Hollywood or Sunset.
It's not impressive to attach green plastic bits to camouflage a cell tower (which IMO makes it uglier and more noticeable than just a bare antenna mast).
It would be extremely impressive if they could actually derive the required power from onboard photovoltaics though!
i wonder what we would come up with if there was a contest to design a beautiful cell tower. a giant tulip? space needle? treehouse? inconvenience store? a blinky scroll tower?
