Years ago I remember my grandfather having a wireless aerial (as it was
known then) down his garden which came through an insulator in the
window frame and was connected to a ceramic knife switch on the window-
sill. This allowed changeover of the aerial from the wireless to earth
during thunder storms. Does anyone know of a source of such switches
these days?

umbrella antenna whenever not in use. Is this the kind of switch you are
looking for?
