Arecibo line feed (or what is left of it)
The good news is that congress has pledged to fix all the damage caused by the hurricane. This means that there will hopefully soon be a new line feed that will replace this one. I heard that quotes for fabricating a replacement have been made.
The other good news is that the Gregorian (dome) wasn't damaged in the hurricane. This means that the 430 MHz radar can still be used, but not anymore in dual beam mode.
