Unlike rigid steel whips that snap on trails, the Super Flex bends and returns. Shorter 2ft antennas sacrifice range; the 4ft flex balances durability and performance for Jeeps, trucks, and buggies.

Frequently Asked Questions
How do I tune a Cobra 4ft Super Flex CB antenna?
Install on a 3/8-24 mount, connect quality coax, then check SWR on channel 20 with a meter. Trim the tip slightly at a time until SWR is lowest (under 1.5:1 is ideal).
Where can I buy the CA-FLX401 and what's the current price?
PowerHaven Outpost has it for $12.48 — 50% off the $24.95 list price — with coupon OUTPOST12 for an extra 12% off.
What SWR settings should I aim for?
Target 1.5:1 or lower on channel 20. High SWR on both ends usually means more trimming is needed or the ground plane is inadequate.
Is this antenna good for off-road vehicles?
Yes — that's its core use case. The flexible fiberglass whip bends on branches and car washes instead of snapping like steel whips.
What coax and mount do I need?
Pair with a SO-239 stud mount and low-loss RG-58 coax, or RG-59 coax with molded PL-259 connectors.

Tough as nails
I do a lot of trail driving and have destroyed two whips on low branches. This CA-FLX401 just bends and springs back — that's the whole reason I bought fiberglass. SWR tuned in easily at 1.3 on channel 19 with a decent tune-up, and reports on my transmissions have been clear. Half price at PowerHaven sealed the deal.

Good antenna, needs a proper tune
Right out of the box my SWR was around 2.5, so don't skip the tuning step — trim a little at a time and it'll come down. Once tuned, it transmits clean and receives well for a 4-foot whip. The flex rating is real; I've backed into a brushy area and it just bounced off branches. Solid value for $12.
