I want to put a CB in my XJ, i know absolutely nothing about them other than cobra is real good and the antenna and coax is real important. I don't understand the peaking and tweaking thing, how do i do that and wheres the best place to get this stuff?

I personally think Uniden is better...like the Pro510xl or Pro520xl. With the audio performance right out of the box you won't need to worry about "peaking & tweaking." In fact, I wouldn't worry about that no matter what radio you end up with (for now anyway). But the Pro-series Uniden is a good wheelin' radio for the money. Rugged, inexpensive, and a decent performer for under $50. I have had one (I have two not to mention a few others) of my Pro510's since 1992 and it's done well.

As far as your antenna goes, yes...it's the most important part of the puzzle. Decide where you want to mount it. Ideally on the roof is best, but that isn't always possible for some people. Being you are relatively new at radios, a simple decent magnet mount like the Wilson Lil-Wil or Wilson 500 are a decent place to start...placed on the roof (assuming you don't have a CJ, YJ, TJ, etc.). You'll want to tune the antenna (which is done with a meter). Often you can simply pay a CB shop $5 or $10 to set that up for you...but once it's done, you shouldn't have to mess with it again. If you are thinking something a little more permanent with a hard mount, you have lots of choices there too...not to mention antennas. But mounting location is a big part of performance.

As far as a place goes, the above items are likely to be competitive no matter where you go. If you are wanting to buy online Walcott CB is okay, but certainly not the cheapest. By the time you ship stuff sometimes could have gotten the stuff locally. My guess is for under $100 you can have all the above (and decent performance) with room to spare. Now if you want a BIG radio with big audio, bells & whisltes, etc. etc. that is a whole other ball game...and will cost many more $$$. But for decent and easy performance, the above should work great and not cost alot.

Hope that helps a little.

I agree 100% with IBTJ’n, just a little more info. If you have truck stop near by, there are usually CB shops near them, some of these guys are real Geeks and do know there stuff.
Uniden radio’s I feel are better that cobra, I’ve hade mine since ‘87 and not a problem, I did own a Cobra and it did live for 13 years, and needed some work now and then.

i use a cobra 148 GTL in my xj. I have it supermodded (more transmitting and receiving power), if your hardmounting your antenna I would get an 18' length of coax (the longer the coax the better the power of it will be). You can essentially mount the "whip" anywhere, but the ideal place for any vehicle is directly in the center of the roof, if you run a co-phase antenna style (used mainly for highways), with co-phase you run two antennas placed on both sides of the vehicle driver and passenger. this makes your "talking range" in front of you or behind you. if you run a single antenna you have an all around talking radius, but it is weaker than running co-phase. if you do mount the whip on a hard mount, I would put a ground wire from the mount to a good ground. I have my whip hard mounted right under the passenger side rear window under the 4x4 badge. when you wire the CB in, i would get a capacitor and wire it into the positive (hot) wire. Run the wires directly to the battery for the best connections. having a bad ground on a cb radio will fry the finals inside. when you have your antenna tuned, this is changing the SWR (standing wave ratio) This is basically a ratio comparing your transmitting power to your receiving power. You want this ratio to be as close to 0 as possible. a 3:1 SWR means you can transmit 3x further than you can hear people, so if people three miles away from you can hear you, you will only hear people that are 1 mile away etc. Having a CB "Supermodded" changes the finals in the radio so you can switch from 5 watts of transmitting power all the way up to 100 watts, depends on your cb shop. Supermodding gets rid of the government restriction on cb radios, switching the finals with some from out of the country where the cb radios are not restricted. 5 watts of transmitting power with a 3:1 SWR will get you about 3 miles of transmitting power. my setup is 75 watts of transmitting power with a SWR of .93 can get about 40 miles or so. if all your doing is talking to your group your wheeling with I wouldn't get your cb tweaked, but you always should tune your antenna. I drive on the highway a lot, so being able to talk to people 40 miles away can come in handy rather than carrying around an illegal radar detector.


No offense, but besides the info' you posted being less than accurate (to put it mildly), it's probably best the original poster ignore it.

Besides, most wouldn't have a clue what you are talking about.
