Provided the mechanical connection is sound, you can use any coaxial
connectors you like, regardless of nominal impedance, at frequencies
less
than about 300 MHz without any observed ill effects.

in most professional operations, including high-power broadcast systems.

Connectors available off the shelf are not perfect, especially the pl259
type that are usually used by many.
While I don't doubt the problems to TV signals, this is an amateur group
type discussion.
Many antennas are nowhere near the 50 ohms that the cable is. Most any
connector will not cause any more problems than the coax/antenna mismatch
will in all but the most demanding systems (maybe EME or some satellite
work).
