What is the value of a remote switch?
What is the use?

It allows having several antennas served by a single transmission line. As an
example, you might have three monoband yagis christmas-treed on a tower a couple
hundred feet from your shack. You might serve this tower with a single run of
presurized hardline, and using the antenna switch at the tower top to select the
appropriate antenna.
