Uh.... Did not know that!
Curiously, How much does one of these 120 amp switchers cost and are
they RF quiet?

There's been a great deal of speculation and advice on here regarding
this,
but in reality, a simple answer to the simple question has been
provided.
There are absolutely 12V, 120A "off the shelf" power supplies readily
available and currently for sale. If someone wants one delivered
tomorrow,
he could have it.
The MagneTek MG3 product is one I've used for a few years now, in
exactly
this category. Delivery is a few days or less, and it's a solid,
certified
product. Not large or heavy, and a twin MG3 pack provides 12V regulated
at
200A continuously. There's a 48v version of the same product.
Unipower, TDI, NMB, Todd and others make similar stuff. Nothing unusual
about the requirement at all, although evidently the ham community seems
to
think so...
