Intro to Basic CB
Our attempt is to help newer people not familiar with CB radios to not be intimidated by the technical details of purchasing, installing, and using a CB radio. This write ups is meant to be general in nature, and may not apply to some applications. We hope this will be helpful, though.
Important General Basic Idea: It is a fact that an inexpensive radio and good quality antenna system will out perform an expensive radio, and mediocre antenna system. Keep in mind that the antenna system really is about 90% of the overall performance of the system we are attempting to put together.

CB / SWR Tuning
Well after find a lack of CB antenna tuning write-ups, I figured I'd write one. The biggest problems I came across was what I did find was a whole bunch of in depth theory, that was rather dry. I don't want to spend days researching this, I just want to tune my CB antenna. This is meant to be a very basic, simple guide to tuning your CB antenna.

CB Antenna Basics
When you are putting together a system for your Jeep, whether on a budget or not, plan on buying the best antenna system (coax, mount, antenna stud and antenna) that you can find and then go buy a radio.

CB Radio RF Noise Suppression
The following dialogue occurred with John, a JU member that I was exchanging on-line posts with while he was attempting to reduce the RF noise in his TJ when he was installing his CB radio. With his permission, I am including it here since I believe it is both valuable info and it gives others a glimpse at just what can be involved in trying to clean up a noisy RF environment in a vehicle. Considering that entire books have been dedicated to the subject, this is just a short review of the things that were done. Please note that some of this is as much magic as it is science....by that, I mean that what may work great for me does absolutely nothing for you and your Jeep's CB radio.....or worse yet, you do it and it makes things worse. There are so many variables in the equation that you must understand that any one or a combination of these tricks (or others not listed here) may be just the cure for your noisy radio.

CB Tuning - Write Up

Any antenna designed to transmit has to be tuned. Failure to tune your CB antenna will result in burning up your CB. Basically if your antenna is not tuned, some of your CB's signal will be reflected back into the radio, if this happens in very short order your CB will be receive only. To tune your CB antenna you will need a SWR Meter. Just in case you are wondering, SWR stands for Standing Wave Ratio.

CB/Ham SWR Meter Operation
Your RadioShack CB/Ham Field-Strength SWR Meter helps you tune your CB or
amateur radio system for the best performance.
CB and amateur radio systems work best when the antenna system's impedance
matches the transmitter's output impedance as closely as possible.
The meter's standing wave ratio (SWR) function helps you trim your antenna
to the precise length you need for the maximum transmitted power.
The meter's field strength function helps you position your antenna for
the best coverage and determine the effectiveness of changes you make to
your antenna, antenna cable, and transmitter.
Carefully read all of these instructions to get the best use from this
meter.

Choosing a CB Antenna
Choosing a CB antenna is fairly easy once you have sorted through a few basic rules. This information should help.

* the CB is an essential tool for traveling in groups on the trail
* the handheld was a lot better than nothing, but did not have the range needed for any communication beyond several hundred yards
I knew it was time for a permanent mounted CB
