CB sound is crappy, is it due to poor cable quality?

I had a cb in my YJ years ago, it got totaled so i took it out and it sit in the garage. Now I installed it into my new TJ and it isnt as loud as it was before. I noticed the cables were a little corroded looking. It kinda gets louder when I wiggle the plug around. I tried fooling with tthe volume and squelch, no avail. You guys think a new cable would solve the problem? or might it be the CB itself?

Go the cheapest route first, get a new cable!

the cable most likely. Also, you might want to find an SWR meter. Radio Shack sells them for like $35. It will help you tune your CB, Cable, and Antenna to peak performance.
Also, it helps to have a really clean contact between your antenna/mount/body. The antenna relies on your vehicle as a ground plane. It affects the reception considerably.

2 most important factors in radio transmission and receive quality are:

1. Good quality RGX or Mini8
2. Antenna tuned properly with SWR meter.

Got ignorance? Please see below.

I would definitely add a good ground connection to that list.

What is a rgx or mini8? I have the antenna bolted to the spare tire carrier (stock) and the andenna is a 64" whip. it attaches to the coil via an allen. can this be tuned? if so how?

Dont bash me, Radio Shack. I just want something that i can use while out with the club on the trails. Is there any way of testing the cb without another cb to make sure it works properly?

Either check or have cheked the SWR (Standing Wave Ratio) of the System.

If it is in the area of 1.1 to 1.5 to 1 then your connections to the antenna are OK.

If above that then you have to have things checked out, connections, coax and ground strap connections.
Sometimes it is as easy as running a ground strap from the Antenna Mount to the Frame, sometimes not.

Start by checking the SWR; see where that takes you then you have a reference point.

The Coax at Rat Shaq will work, yes, but it will also bring in noise and lose more power on transmissions.
I am a against Rat Shaq only because I believe they are taking advantage of people by selling inferior products, I don't mean to bash anyone just the Rat shaq Products.
If you notice Rat Shaq is selling Name Brand Products, they are going away from the Radio Shack Name.

Luck on the project,

Do it right the first time !

RG8X and Mini8 is simply a bigger diameter cable than the standard RG58 cable most CB'rs use. That said, as someone who has been using RG8, RG8x, min-8 and other coaxes since the sixties, you won't be able to tell the difference on a 4 watt CB with basic less costly more flexible RG58. There's simply not enough loss in the 12-15' length of antenna cable for it to make any difference to a CB by using RG58.

Yes it could be tuned but unless it can be moved up and down after loosening the allen bolt, it won't be easy. If it can be moved up and down in the mount, then it can. Use an SWR meter (they include instructions) to tune for minimum SWR and the antenna is tuned.

A mistuned antenna will not affect how well it receives however, that only affects how well it transmits.

So far as things making noise when you wiggle a cable, which cable are you talking about? The antenna cable or power cable? Either way, a connection is likely just corroded which could probably be fixed by just cleaning it up and maybe resoldering it.

When you have a choice, buy American made.

The coax cable is what made noise. I think i might have it too long as well, there was plenty extra so i tucked it under the carpet, probably a bad idea. It seems many of the CB/ trucker shops are closing around Los Angeles. Anybody recommend someplace to get some cable? What length should I buy? I have it coming out the back, where the tailgate hinges and it is mounted on the spare tire carrier.
Thanks
