What is the best way to use one feed line for more than one dipole?
Or, is it better to use a coax switch in the shack?

Ron, your subject line "Two dipoles on one coax" implies the typical antenna
selector switch that leaves no question (of course you can do that). But the
message body asks about one feedline for more than one dipole as opposed to
the antenna selector. The two choices are so unequal that a comparison is
not possible.

Someone may explain here that they have connected more than one antenna with
a single feedline, but it flies in the face of proper operating procedure.
Most operators however do use antenna selector switches to provide more than
one antenna choice to a given receiver or transmitter. The individual
antennas always have their own individual feedline in those cases.
