NASA IV&V Facility, Fairmont WV
This is a 10 meter C band satellite antenna manufactured
by Andrew before it was bought by Commscope, which spun the satellite
antenna division off as a separate company, ASC Signal, in 2007, which
means it was installed some time before that date. My memory is
terrible, but I think it was put in some time around 2005. There's a
smaller C-band downlink/TVRO antenna behind it with a dual polarity
feed.
This type of antenna uses what's called a Cassegraine
feed; the feedhorn protrudes from the center of the dish, pointing at a
small sub-reflector that illuminates the dish. This dish has a gas
powered de-icer that blows warm air between the back surface of the
dish's reflector and the fiberglass backing panels. There's also a tube
that blows warm air over the feedhorn. The two spikes sticking out of
the top are for lightning/ESD protection, they're meant to reduce the
buildup of static electricity that would attract a lightning strike.
I'm not sure what it's used for here, this type of
antenna can be used as a high performance downlink or as an uplink
antenna. The facility it's attached to is the NASA IV&V facility in
Fairmont WV. IV&V stands for "independent verification and
validation", which means they do something vague relating to software
used on NASA spacecraft. I got to take a look around this facility a
few years ago, but the guy that was showing me around either didn't
know anything about this dish, or its use falls into the category of
stuff I'm not allowed to know about, like the room where they do the
alien autopsies or the underground maze they keep all the space lasers
in.
Making a cameo appearance, you can see Jesus' golfball behind the dish.
