Tram 1500-Watt Fiberglass Whip CB Antenna vs Comet CA-2x4SR Mobile Antenna

Buy the Tram 1500 if your radio is a CB and you want a simple, tough fiberglass whip that handles high power. Buy the Comet CA-2x4SR if you also use 2m/70cm ham or scan those bands, since it covers far more frequencies with real gain. The Tram is a single-band CB antenna with a 1,500-watt rating and a 3/8-inch stud mount; the Comet is a shorter dual-band antenna rated 150 watts with a fold-over hinge and a PL-259 base. Owners of fiberglass whips like the Tram report they hold up to weather and flex; the Comet is the more versatile antenna but its lower power rating and UHF mount suit ham and scanner use more than high-power CB.

  • Choose the Tram 1500 if you run a CB radio, want a rugged fiberglass whip, and need headroom for high transmit power.
  • Choose the Comet CA-2x4SR if you want one antenna for 2m, 70cm, CB and scanner listening, and value the fold-over hinge.

What reviewers say

Comet CA-2x4SR Mobile Antenna

Owners of the CA-2x4SR generally report it works well across 2m, 70cm and scanner bands, with low SWR on the ham frequencies. Complaints center on its height and the need for a good mount and ground plane.

What people mention
  • SWRPraisedOwners report low SWR on the 2m and 70cm ham frequencies.
  • Receive coveragePraisedUsers like that it hears scanner and CB frequencies beyond the ham bands.
  • HeightCriticisedAt 40 inches it draws attention and can hit low branches.
  • MountingMixedResults vary with the mount and ground plane used.

Questions and answers

Which is better for CB radio?
The Tram 1500 is the dedicated CB antenna, covering 26-29 MHz with a 1,500-watt rating. The Comet works on CB but is tuned primarily for 2m and 70cm, so it gives up some CB performance.
Which handles more power?
The Tram is rated 1,500 watts; the Comet is rated 150 watts. If you run an amplifier on CB, the Tram has far more headroom.
Can the Comet replace a CB antenna and a scanner antenna?
Yes. It covers 2m, 70cm, CB and scanner bands, so one antenna can serve a ham rig and a scanner. The Tram cannot do that.
Which lasts longer?
The Tram's fiberglass whip is built to flex and resist weather, which suits permanent vehicle mounting. The Comet is a slimmer whip with a fold-over hinge, a moving part that sees wear over time.
Is the Comet worth stepping up to?
Step up to the Comet if you use ham or scanner bands and want one antenna with gain and a fold-over hinge. Stay with the Tram if CB is your only use and you need high power.
What else do I need to install either one?
The Tram needs a 3/8-inch stud mount; coax and hardware are included. The Comet needs a UHF mount and its own coax, since neither is in the box.
