Quick answer: How High Does A CB Radio Antenna Need To Be?

Why is my SWR so high?

Short.

The most common cause of a high SWR is an antenna shorted to ground.

There are two places a short can occur in a CB antenna system, in the coax and in the antenna stud..

What happens if you transmit without an antenna?

You could potentially break some radio transmitters by operating them without the antenna connected. Several things combine to make this possible. First, it’s difficult to make power at RF frequencies, so the power devices are often fairly fragile, and run near their limiting conditions.

Can a CB antenna 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 many miles can a CB radio transmit?

A – “Generally Speaking”, range for a mobile CB Radio could be anywhere from 1 or 2 miles, to even 20 to 25 Miles or more, depending on the terrain, type of antennas used, & other factors.

Does CB antenna length matter?

Choosing the Optimal CB Antenna Length Yes, taller/longer is better for range of distance when it comes to an antenna and the optimal antenna length is 1/4 wavelength. That translates to 102 inches (8.5 feet), too tall to be practical for most mobile applications.

Can a CB radio be traced?

Not hard to do, since all you need is a CB. And yes, the FCC can track where a CB is transmitting from, Heck, they can even tell what kind it is etc. BUT, thats if you’re a real bad guy threatening The Prez, for instance, not some backyard dunce with a base station harrasing us poor truckers.

Where is the best place to mount a CB antenna?

The best place for your standard antenna is the center of your roof, where you will have the greatest ground plane coverage. When you install a CB antenna on the fender, bumper, or anywhere else around the edge of your vehicle, you will have a weaker signal going away from the vehicle.

How long should my CB antenna be?

Choosing the Optimal CB Antenna Length Yes, taller/longer is better for range of distance when it comes to an antenna and the optimal antenna length is 1/4 wavelength. That translates to 102 inches (8.5 feet), too tall to be practical for most mobile applications.

What does 42 mean in trucker talk?

A: If you hear a truck driver say “42” on their CB radio, it’s just another way to say “Yes, or OK.” There are hundreds of other popular CB slang phrases – to learn more, check out the links below or browse the rest of our online CB slang dictionary.

Do truckers still use CB radios 2019?

The CB radio is not completely dead. In fact, a lot of truck drivers still use the CB radio, because that is what they have been using for 5, 10, or even 20+ years. … Several truck drivers now find themselves using trucking apps on their smartphones to communicate, like Next Trucking, for example.

Can I use 75 ohm coax for CB?

RG-59 and RG-6 are 75 Ohm coaxial cables designed for cable television applications, they tend to have wide frequency response and low line loss. … You can use these cables with a 50 Ohm amateur radio antenna system, but because of the impedance mismatch, your SWR will be a little higher.

Does a CB radio need an antenna?

CB Radio – Most new CB radios come with a microphone, mounting bracket and power cord, so you won’t need to buy those separately. CB Antenna – Without an antenna, your radio is useless! … If you’re using a magnet, roof or trunk-lip antenna, the coax is likely included with the antenna mount.

How do I increase the range on my CB radio?

How to Increase the Receiving Range on a CB RadioInstall an antenna specifically manufactured for use with CB radios. … Place your antenna as high as possible, in a place where radio signals can hit it from 360 degrees. … Adjust the squelch on your radio so that it blocks out static, but is not maxed out.More items…

Does coax length affect SWR?

Many antennas have a SWR of just over a perfect match like a SWR of 1 to 1.2. This is measured at the antenna itself. With a length of coax the SWR will now show a SWR of say 1 to 1.0 , because of the loss in the coax. And so will the bandwidth change a little.
