Why is my Cobra CB not working?

Check Fuse Make sure the CB radio’s fuse is not blown and that it is seated correctly. Also check the in-line fuse for the CB radio’s power cord- if it is burned out, your radio will not power on.

Why is my CB radio all static?

CB radios can be affected by engine motions, cellular broadcasts, and electrical wires which can cause white noise and static on the CB, reducing the radio’s effectiveness. Aside from the filters, using the squelch function on the radio can help reduce the noise.

How do I get better reception on my CB radio?

There are several procedures for ensuring maximum output.

  1. TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it.
  2. USE CB-SPECIFIC ANTENNAS.
  3. ESTABLISH A GROUND PLANE.
  4. CHECK THE VSWR.
  5. ELIMINATE RESISTANCE.

Does a CB antenna need to be grounded?

Ground Your Antenna Mount If you’re using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you’ll need to make sure your antenna mount is solidly grounded to the vehicle’s chassis. A bad ground will result in an un-tunable antenna and sky-high SWR levels.

How do I know if my CB antenna is bad?

How to Test for a Defective CB Antenna

  1. Using your multimeter, touch one of the probes to the metallic end of the antenna.
  2. Touch the other probe to the metallic threads at the end of the antenna.
  3. As you maintain contact with both probes, measure the circuit’s resistance.

Why does my CB have so much squelch?

So what does the squelch do? It sets the threshold where sound will come out of your speaker. The higher you turn the squelch, the stronger the incoming signal will have to be in order for you to hear it. This has no affect on the receive as indicated by the meter.

How do you test a CB antenna ground?

If your CB antenna mount has a good ground, the multimeter needle should move all the way to the right when the probes contact these two locations. If you get very little or no needle movement on the multimeter, test that your meter is working properly by touching the two probes together.
