This is absolutely correct, especially when talking about mobile antennas. Even the "no ground plane" antennas that are available have a built in ground plane of sorts, usually in the form of a custom coax cable.

About the only antennas that don't require some form of ground plane are balanced antennas, such as dipoles. With these antennas the counterpoise is a part of the radiating antenna, and not a groundplane.
