To summarize, tuning a CB radio without an SWR meter is possible. Though time consuming, it simply requires you to gauge the performance of your radio while using a second CB radio that had been pre-tuned. It will then involve making small adjustments to your antenna until you can get a clear signal.
Do you have to tune a CB antenna?
Tuning your antenna is mandatory if you want acceptable CB performance. Not tuning your antenna will result in poor transmission and reception performance, and can also result in permanent damage to your radio. You’ll need an SWR meter (available for around $25) in order to tune your antenna.
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
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.
Will a CB radio work without an antenna?
Scientific fact: CB radios work better without an antenna.
What is the best height for a CB antenna?
Generally, the higher the antenna is above ground, the better it will perform. Good practice is to install your vertical antenna about 5 to 10 feet above the roof line and away from power lines and obstructions. Remember that the FCC limits your antenna height to 60 feet.
How can I increase the range of my CB radio?
There are several procedures for ensuring maximum output.
- TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it. …
- USE CB-SPECIFIC ANTENNAS. …
- ESTABLISH A GROUND PLANE. …
- CHECK THE VSWR. …
- ELIMINATE RESISTANCE.
Why does my SWR go up when I talk?
One of the most common causes of high SWR readings is incorrectly connecting your SWR meter to your radio and antenna. When attached incorrectly, readings will be reported as being extremely high even if everything is installed perfectly. Please see this article on ensuring your SWR meter is properly installed.
What does Delta Tune mean on a CB?
The delta tune is the CB name for a very similar function on amateur radios called RIT, or receive incremental tuner. The Delta Tune controls the frequency your radio’s receiver is operating on.
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.
Why does my Cobra 29 LX say antenna warning?
This alert that you are seeing is only supposed to basically come up on that screen if there antenna is not connected. There is a simple adjustment inside the radio. The component is a little potentiometer that has to be turned with a little tiny screw driver.
