42 Inch Magnet Mount CB Antenna vs 1198 CB/Weather-Band Glass-Mount Antenna

Buy the 42 inch magnet mount if you move the antenna between vehicles or want a tall whip for longer range. Buy the 1198 glass mount if you want a permanent, low-profile install with no drilling and no magnet to slide off in rain. The magnet mount is heavier and its 15-foot cable is fixed, and owners report the magnet letting go in heavy rain. The glass mount is a thinner, sealed-on setup, but it needs a clean glass surface and careful tuning to work well.

  • Choose the 42 inch magnet mount if you switch between cars, trucks or rentals and want a tall whip you can lift off and move.
  • Choose the 1198 glass mount if you want a fixed, low-profile antenna bonded to a window with no drilling and no magnet to lose grip.

Questions and answers

Which is better for switching between two vehicles?
The 42 inch magnet mount. It lifts off the roof or trunk in seconds. The 1198 glass mount bonds to one window and is not meant to move.
Which holds up better in rain and wind?
The 1198 glass mount. Owners of the magnet mount report the base sliding off the roof in heavy rain. A bonded glass mount has no magnet to lose grip.
Which gives better range?
The 42 inch magnet mount, in general. A taller whip with a good ground plane reaches farther. The glass mount is shorter and its performance depends on the glass install and tuning.
Is the 1198 worth stepping up to?
Yes if you want a permanent, low-profile install and never plan to move the antenna. If you need to move it or run high power, the magnet mount is the better fit.
Do I need to tune either one?
Yes. Both need the whip trimmed or adjusted to get low SWR on your radio. Check SWR before transmitting.
Which lasts longer?
The 1198 glass mount usually lasts longer because nothing lifts off. The magnet mount's weak point is the magnet grip and cable, though it carries a limited lifetime warranty.
