Our take on the Uniden BCATPL259-19 Magnetic Mount CB Antenna 18"

The Uniden BCATPL259-19 is an 18-inch magnetic-mount CB antenna with a PL-259 connector, pre-tuned for CB channels out of the box. The short whip and strong magnet make it a low-profile option for drivers who want a temporary, no-drill install on a car, pickup or RV roof. It is a compromise antenna: the stubby length keeps it out of the way and easy to remove, but it will not match the range of a taller whip or a permanently mounted antenna. It suits casual CB users, convoy drivers and anyone adding a radio without cutting holes.

What reviewers say

Owner feedback on this antenna is limited, but the pattern for short magnetic CB antennas is consistent: buyers like the quick setup and low profile, and accept weaker range as the trade-off.

What people mention

  • MountingPraisedThe magnet base goes on and comes off in seconds with no tools.
  • Magnet gripMixedIt holds well on clean flat steel but can shift on curved or dirty surfaces.
  • SizePraisedThe low 18-inch profile clears garages and stays out of sight.

Questions and answers

Does it need tuning?
No. It comes pre-tuned for CB channels, so you can connect it and talk. A quick SWR check is still wise after install.
Will it work on a fiberglass or aluminum roof?
No. The magnet needs a flat steel surface to hold and to work as a ground plane. Use a through-hole or lip mount on other bodies.
What radio does it fit?
Any CB radio with a standard SO-239 antenna socket. The PL-259 plug screws straight on.
How does it compare with a taller whip?
It is shorter and easier to live with, but a taller whip or permanent mount gives more range. Choose this for convenience, not distance.
Can I leave it on in a car wash?
Remove it first. The magnet holds at speed, but brushes can catch the whip and pull the base.
