A ground plane or a tuned counterpoise does not. A rule of thumb is that if the
conventional aperture is 1/2 wave across or more, you won't need the choke.
Smaller and you will.

Any antenna feed with a coax transmission line will benifit from using
a choke/balun at the antenna feed point. It is just good engineering
practice to do so. It won't hurt and only can help.
