There’s always a ground. Whether it’s what you intend it to be or not is another issue… A mag-mount antenna is grounded through capacitive coupling between that magnet and the metal it’s stuck to. At VHF/UHF frequencies, this effect is adequate for good results which explains the popularity of these mounts.

How does CB antenna work?
A citizens band (CB) radio antenna is a device designed to do two things: It captures radio-frequency signals that are then converted to electrical signals by the receiver, and it takes electrical signals from the transmitter and converts them into radio-frequency signals.
How do you tell if your CB antenna is grounded properly?
An easy way to test your antenna’s ground is check continuity between the CB antenna mount and your vehicle ground, because if the antenna mount is well grounded, so is your antenna. To test for continuity of electrical signal, you will need to touch the probes for your multi-meter in two locations.
