Driver Extreme 40" Silver Bullet CB Antenna vs 42" Fiberglass CB Weather Band Antenna

Buy the Driver Extreme 40" if you run power or want to tune the antenna yourself; buy the 42" DRX-5421 if you want a simple install on a stock CB. The Driver Extreme is the sturdier build: 1/2" rod, 15-gauge wire, stainless stud and a 1000-watt rating. The 42" is thinner at 3/8" and rated 300 watts, but it comes factory tuned and needs no adjustment. Both cover CB and NOAA weather, and both use the same 3/8-24 mount.

  • Choose the Driver Extreme 40" Silver Bullet if you run an amplifier, want a thicker 1/2" rod, or prefer to tune the tip yourself for the lowest SWR.
  • Choose the 42" Fiberglass CB Weather Band Antenna if you want a bolt-on antenna that is factory tuned and you run a stock or lightly boosted radio.

Questions and answers

Which is better for a stock CB radio?
The 42-inch. It is factory tuned and its 300-watt rating is well above what a stock 4-watt CB puts out. The Driver Extreme works too, but you would tune it for no real gain.
Which handles a linear amplifier better?
The Driver Extreme 40". It is rated to 1000 watts, while the 42-inch is rated 300 watts with a 400-watt maximum. Running a big amp on the 42-inch risks damaging it.
Which lasts longer?
The Driver Extreme has the heavier build: 1/2-inch rod, 15-gauge wire and a stainless stud. The 42-inch uses a thinner 3/8-inch rod and a brass ferrule, so it flexes more and its base can corrode faster.
Do both receive NOAA weather?
Yes. Both list the 162-166 MHz weather band, and the 42-inch is marked NOAA alert ready. You still need a CB with a weather receiver to hear it.
Is the Driver Extreme worth stepping up to?
Only if you run power or want to tune SWR yourself. For a daily-driver stock radio, the factory-tuned 42-inch is the easier install.
Will either fit my existing mount?
Both use a 3/8-24 threaded base, the common CB stud size, so either fits standard mirror, fender or stake-hole mounts.
