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

The 42-inch magnet mount is the better pick for most shoppers. It has a longer whip, higher power handling, a limited lifetime warranty and much stronger owner feedback. The Tram glass-mount is the choice only if you cannot use a magnet, such as on a fiberglass or aluminum body, or want a permanent low-profile install. Owners of the magnet mount praise reception once tuned but complain the magnet can slip in heavy rain, so check your roof material first.

  • Choose the Tram glass-mount if your vehicle has no steel roof or trunk lid for a magnet, or you want a permanent, low-profile install with a longer cable run.
  • Choose the 42-inch magnet mount if you have a steel roof or trunk lid and want the strongest reception, more power headroom and a warranty.

Questions and answers

Which gives better range?
The 42-inch magnet mount. Its longer whip and higher power rating generally give more range than the 28-inch glass-mount.
Which lasts longer?
The magnet mount carries a limited lifetime warranty and rates higher with owners. The glass mount has no stated warranty and its adhesive bond is the weak point.
Will the magnet mount work on my vehicle?
Only on a steel roof or trunk lid. Fiberglass, aluminum and most composite panels will not hold it, so the glass mount is the safer choice there.
Is the glass mount worth stepping up to?
Only if you cannot use a magnet or want a permanent install. Otherwise the magnet mount offers more range and a warranty for less compromise.
Does either handle a linear amplifier?
The magnet mount is rated to 300 watts. The Tram lists no power rating, so keep it on a stock radio.
Can I move the glass mount to a new car?
Not easily. The adhesive pad is bonded to the glass, so removal usually means replacing the mount.
