The Metra WM-CB70 is a 26-inch steel CB antenna on a magnetic base with a two-section mast. The magnet lets you set it on any flat steel surface and lift it off when you park, so no drilling or permanent mounts. It is a basic, low-cost whip for drivers who want simple road communication, not a tuned high-power setup. Compared with fixed-mount antennas it trades range and stability at speed for easy removal, and owners say it works fine for casual CB use.
