Do Outdoor-Mounted TV Antennas get less effective with age?

They can do if you get water into the coax or the balun fails.

Do the pivot-points of the elements need to make a good *electrical*
connection,

No, but the coax does to what it connects to.

or is proximity good enough?

They just need to be where they are supposed to be.

That's with the more common yagis. There are some
other less common types of TV antenna that do need
the elements electrically connected.
