This photo shows part of a large antenna assembly which has a series of thin wire protrusions:
This antenna is apparently used for TV transmission.
What are those protrusions for? I'm guessing something to do with lightning or static? The photo is from near the antenna's base, it was hard to tell how far up they go.
(Interesting video, BTW as the giant antenna has to be replaced by helicopter at the top of a 1500 ft tower)
