i really want a cb radio in my car since im on the highway alot. just wondering if anyone suggests a nice cb or knows about installing them. i want to get a big 62" whip antenna too. like the duke boys haha. i live in the country and we dont have cell phones yet

Uniden or Cobra's higher end units are worthwhile. Although modifying 10-meter ham radios will give you more power, and the audio quality is often times better than "export" CB radios. I use an Icom two-way radio that I modified for covering the CB band (simple as cutting a diode on the circuit board)...the antenna is a 102" full-size whip off the rear quarterpanel. Depending on terrain, I get about 15-20 miles.

The antenna is really the key. Get the biggest **** one you can fit, and mount it on a metal part of the vehicle. Drilling a hole is the best way to mount an antenna, I've never been a fan of "mag-mount" antennas, especially for CB. Not only do they scratch the paint and collect moisture, but they don't provide a good RF ground at CB frequencies.

i was looking at a 62" whip. magnet mount for my car but im defietly not drilling a hole in my trunk. also what is ;ham" and how do you get more watts out of a cb

you just want one so you can tell everyone else you have no ******* on. also you want to look for some lot lizards

OK...do you have a place you can bolt an antenna to on the underside of the vehicle? I've seen people bolt brackets to the underside of the bumper or frame, and mount an antenna off that.

If it's a trunked car we're talking about, mounting a whip on the edge of the trunk is the next best option. You'd only have to put three screws into the metal, and it wouldn't be visible from the outside. This is what the police do for their low-band antennas.

If you're really committed on a mag mount, fine...just know that they have a tendency to scratch paint, collect water and moisture underneath them, and be prepared to replace coax every few years as opening and closing the door tends to kink and damage the feedline.


also what is ;ham"

Ham (or amateur) radio is a licensed radio service, like CB but it allows you to do a lot more - use a lot more power, talk a lot farther. There's an amateur radio band on 10 meters, just above the unlicensed CB channels...so most radios built for amateur use can be easily modified to drop down into the CB band.


and how do you get more watts out of a cb

You can't, unless you use an external amplifier.

cool im definetly going to not drill holes. ill just get a mag mount and put a piece of cloth between the car and the magnet. im still investigating the radios. also did you say somthing like you cant get every channel with a regular cb?

i dont know of a good basic cb. im not a trucker or anything just want somthing that works.

Just about any CB can be peaked out on power. No need for an external unless you just want one. Radios very anywhere from 11 watts stock output to 200 (modified of course). Galaxy, Connex, Ranger, Stryker and General all make great 10 meter radios that can be converted and peaked. Cobra and Uniden make the some of the most reliable radios that don't require any mods to work great and last. As far as channels go, all CB's made in the last 25 years or so have the basic 40 channels. Then you have radios with side band channels (Cobra 148, Galaxy 959, etc) Then you have the 10 meter radios after converted have multiple bands (A thru E) with 40 channels on each band, plus some radios have a 10k up switch which then gives you half channels. If your just looking to keep up with truckers and cops, a basic radio will do. Any of the extra channels, you only be able to talk to someone you wanted to have a private convo. with ..

Cobra 29 LTD Classic. One of the best out there.

I built a few of them, and they were bad ***. I'd like to have another, but no one around talks on them anymore.

I probably sale more 29's then any other radio. Their bullet proof for a basic radio.

what do cops talk about anyway

nothing really. Around here they jack with truckers and act like another pavement pounder. Ch. 9 is the national emergency ch.

B.S. , start fights, try to catch them doing something illegal.

dont put a piece of cloth between thev magnet and the car=no ground,and yes most any cb can be tuned up and get more watts out of it, i prefer connex,general,magnum.i was and still am in this buisness for over 15 years.thnks jon.

how do you tweak the cb to get more watts? Ive dealt with mag mounts n they stink buddy has a basic uniden and 102" whip and gets like 10-20 miles probably my cobra 24 and wilson 400 which is even a good mag mount gets like 5miles ...

First, the reason the 102" whip works is because that is the perfect length antenna for 11 meter use. No tuning required, every other antenna in the world has to have the standing wave set. This is the ground plain relationship of the antenna and the vehicle matched. If you have a crappy standing wave and the best radio in the world you won't talk 1/2 mile. Also you can't just mount an antenna anywhere you want just for a certain look. Location and ground factor alot into it.

Second, on the CB wattage thing. Most radios have diodes, transistors, resistors and what-not in line on the output (like a car audio amp) to meet FCC regulations.
The FCC limits power on the 11 meter band to something like 11 watts or so. After mods, and removal of certain parts and "alignment" radios will work to their manufactured ability.

Just a minor nit to pick...CB is 11 meters, 2 meters is a really common amateur band up around 144MHz :)

The only problem I see with modifying purpose-built CB rigs is that their RF circuits might not like running with closer tolerances, once you start tweaking coils and biasing transistors higher you're asking for more spurious emissions and splatter across channels. If you have an RF spectrum analyzer this isn't a problem as you can see the transmitter's output, but if you're going blind it could be an issue...

Having a good antenna is more important than having a lot of power. You can't talk to someone if you can't hear them in the first place :)

Yeah my bad. I just realized I put that as I read your post. Thanks...
Yeah the antenna is the more important of the 2 for distance/performance. A Pro510 on a great antenna, will outtalk a Connex on an untuned top of the line antenna.

my brother had a galaxy big rig series with a wilson 2000. he talked to evrything within a 5-8mi range (depending on place and weather). They are a little expensive, but have awesome performance.
