Shot at by who? Islamic terrorists?
No, other idiots.
Same mentality as those who used to shoot out the nav lights when there was a lane of entry, and probably the same who shoot out road signs.
It is an isolated area, and said to be an ongoing problem at YWE, explained at RAPAC. Understandably it was unacceptable to expect techs to work inside the antenna housing to repair the antenna with the potential for the problem to happen again whilst doing so.
Like many things, publicity can result in an increase in occurrences including elsewhere.
Anyway, thread drift - back to the topic.
