How to Tune for the Best SWR

Getting the lowest SWR from your Cobra 4 ft fiberglass CB antenna takes a few minutes:

1. Mount the antenna securely and route the coax to your radio.
2. Set your CB to channel 20 and key the mic while reading SWR.
3. Trim the stainless whip in small increments if SWR is high on all channels.
4. Check channel 1 and channel 40 — a matched antenna shows SWR under 1.5:1 across the band.

Tuning Tips

SWR high on channel 40 means the antenna is too short or mounted poorly; high on channel 1 usually means it is too long. Trim slowly and retest. Tunable-tip design means you adjust once and you're set.

NOAA Weather Band Reception

Yes — the CA-4FTBL supports weather band reception when paired with a Cobra CB radio that includes NOAA weather channels, giving you alerts and forecasts on the trail or the interstate.
