Do CB antennas go bad?
Do CB antennas go bad?
Though rare, a defective or broken antenna can be the cause of high SWR problems and poor performance. Luckily, testing an antenna is a fairly easy process.
How do I increase the signal strength on 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.
Can high SWR damage a radio?
High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn’t usually an immediate failure, it takes some time for that heat to build up and do damage.
Why is my CB not transmitting?
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.
How do I reset my cobra?
Guide To Hard Reset/Factory Reset AT Cobra

- Step 2: In settings, find and select the “Restore Factory Settings” option.
- Step 3: Now, It will ask you to type your phone password in order to proceed with the factory resettings opertion.
What is SWR on a CB radio?
SWR stands for ‘Standing Wave Ratio’ and basically speaking it is “the ratio of power that is reflected back down the antenna lead from the antenna.” Therefore SWR is concerned with matching the antenna to the signal being transmitted through it.
When was the first CB radio invented?
CB Radio (all types) first introduced in 1958. First introduced in 1958, Citizens’ brand radios, also known as CB radios, are a land mobile radio system, which is a system that allows short-distance person-to-person bidirectional voice communication between individuals using two way radios operating on a 40 channel 27 MHz band.
Can I use a CB radio without a license?
CB radios can be used for private or business use without a special license in most countries. Citizens’ brand radios are distinct from other personal radio service allocations like FRS, GMRS, MURS, UHF CB and the Amateur Radio Service (“ham” radio).
What is the range of a CB radio?
Users on a channel have to take turns speaking. The power of transmitters is limited to 4 watts in the US and the EU and CB radios have a range of approximately three miles (4.8 km) to 30 miles (32 km) dependent on the terrain—for line of sight communication.
Can two CB radios transmit at the same time?
However, only one can transmit at a time. Usually, CB radios are in “receive mode” to receive transmissions of other radios on the channel. In the case users want to speak, they press a “push to talk” button on their radio which will enable their transmitter. Users on a channel have to take turns speaking.
