Can SWR be too low?

An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less. We EXPECT a high quality “short” antenna to be narrow banded.

How can I make my CB radio more powerful?

There are several procedures for ensuring maximum output.

Is 1.5 SWR good?

SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. Occasionally, due to installations or vehicle variables, it’s impossible to get SWR lower than than this. You should try to get it lower, but performance should still be acceptable in this range.

What does it mean when your Cobra CB says antenna warning?
