Wikipedia says that the receiving antenna platform weighs 900 tons and is suspended by cables almost 500 feet above the reflector dish. I wonder how that would do in a hurricane.
If that receiving platform comes crashing down it’ll ruin the dish, geez, what a mess to fix.
I’ve been to Arecibo. It is gigantic! It was featured in the movies Goldeneye and Contact. If I’m not mistaken it was built in a sinkhole.
