The cops do not talk on the CB. You can hear other drivers talking about where the cops are. However, in many rural areas, Emergency Services do monitor CB Ch9 to listen for emergency traffic. Ch9 is never used for anything other than emergency communications.

As far as what I do, I talk to other people in my convoy, I listen for info about cops, and I talk to other random people in traffic when I get bored.

They're only barely better than no antenna at all. Seriously, just don't do it.

I recently got a sweat deal on a BCD396 digital trunking scanner but have yet to put it to use in the car. I'm thinking of getting a head unit for it but wanted to see if anyone else has thought it was helpful in car operations of their radios.

Getting a remote head/control face is absolutely the way to go. It makes it so much easier and safer to operate the radio.

I found this page that seems to cover a lot of the things that williaty has been talking about. http://www.larsen-antennas.com/techr...concepts.shtml Not all of it pertains to CBs, but I'd still recommend looking through it if you would like to get a better understanding.

My initial thought was that there was no way in hell I'd drill a hole in my roof for an antenna, but I'm really tempted to do it now. Come fall, I'll be doing a lot more highway driving so I may be able to justify it then.

Putting a hole in the roof is only mentally bad. Once you drill it, you quit worrying about it.

If you ever decide you don't want it, you can put the rain cap on it and tell the guy you sell it to that it's a cell phone booster

Unless the spaghetti noodle said "Firestick" on it. Then it would have one million dB of gain.

How many channels you receive has nothing to do with the size of the antenna.

That little stub, if it can be tuned to the 11m band at all, would have crappy performance compared to a longer antenna. My guess is that's actually a UHF (70cm) antenna. It's about hte right length for that. Or perhaps a scanner antenna, if the person wasn't too concerned about performance.
I wasn't able to get optimal performance on all channels with my old setup on the trunk and a roof mount would obviously improve performance. Would a shorter antenna on the roof be better or the same as a 2 footer on the trunk? Hmm possibly? Sounds like it could be relative. That's what I was really wondering.

Longer is better. The difference between the roof and the trunk is less important than getting a longer antenna. I would look at a minimum of a 3' antenna for CB. Get one with a really flexy whip (the Larsen NMO27B, for instance, tapers towards the tip to get bendier) and paint it black. At wost, it'll make you look like an RC car, which is hilarious.

I actually got a good laugh from this post... You're mocking CB noobs. Wait wait wait... let me say that again. You're mocking....CB noobs...

There's a lot of info out there for those of you wanting to learn more about CB and it's history. This forum is one I used for research a couple of years ago when I was wanting to get back into it.

http://www.cbradioforum.com/index.php?

It looks like it's still pretty active too.

This antenna was part of a special edition package called the "Cobra 20XTR Extreme Street Communicator." More of a novelty if anything the Radio and Antenna illuminate when transmitting. I bought it to match the novelty of my Justy. Very limited range. No it is not tuneable.


I currently use a Uniden PC78 Elite mated to a Wilson K40 Antenna on the trunk. To boost performance I had the radio "peaked" & antenna "tuned" for about $30 at a CB shack. Aparently I'm pushing 25watts on the key. Excellent transmission 5 miles away with audible communication at 10 miles. The Uniden is just larger than full DIN so I modified (Dremeled) the Subaru Genuine Part "Gauge Pod Housing WRX / Impreza 2002 - 2005" to mount the radio.


My speaker is wedged in my arm rest. Sorry no pic.
However another option is the Cobra 18 WX ST II. Its a perfect one DIN and requires no modification of the DIN pocket. The speaker is integrated and faces front...(the little holes)

1) Antenna tuning is absolutely required for every single setup. The antenna has to be installed where it will ALWAYS be on the car, and then then length of the antenna is adjusted to make it resonant for the necessary frequencies.

2) Peaking the radio may or may not be a good thing and may or may not be legal. With the key down and no input (aka transmitting silence), a CB radio's carrier wave may not exceed 4W by law. Peaking, done properly, ensures that the voice signal causes the largest power output increase possible without distortion. There's two problems that people run into with having a radio peaked.

First, shops don't always use techs who actually understand what's going on. Anyone can make the radio output more power just by turning up one of the pots. However, there's a limit where the transmitter itself begins to distort the waveform. Power continues to rise above that point, but the ability of someone else to hear you actually goes down. Additionally, it's possible to set the radio to exceed the 4W dead key legal limit. For about the last 15 years, that's been a big "so what? It's not like the FCC is going to do anything about it." However, we just recently got a new set of enforcers at the FCC and they have been laying the smack down. They are aggressively going after CB operators using more than legal power, CB shops selling parts or services that enable operators to use more than legal power, and CB operators operating out of channel. While the odds of you being dinged are small (there's a lot of CB ops, and you're only one), it's NOT worth the risk. FCC doesn't screw around. IIRC, the minimum fine they can asses for this is $10k.

I appreciate this thread for finally getting me to install the 2m/70cm rig that has been sitting in my office floor for months now. The last time it was in a vehicle was around 2000 when I crashed my truck and the mounting bracket chopped up my knee (take heed to Ty's comment about placement).

Oddly enough we have a world class ham radio shop in our area so after work today I drove over and bought a remote mount kit for my Kenwood TM-V7A and the Larsen antenna that Ty recommended.

Here is where I have installed the remote display:



I will most likely put the chassis under the seat (versus the trunk) so I don't have to mount a remote speaker to hear it. The antenna will go on the trunk between the front lip and the wing. Might be interesting to install as the trunk has a stiffener under the sheet metal that I have to drill through. I would man up and put the Larsen on the roof, but it won't clear my garage door on the way in.

As for CB radio, I like the idea of a DIN sized unit in the OEM gauge pod, but I really don't think I would get much use from CB. I can't stand to listen to truckers and the compromise to get an efficient 11 meter band antenna is not worth it for me.

I did do the CB thing in a big way 30 or so years ago. My Dad was nutty for the stuff and had a big tower by the house and the obligatory 108" whip on his 1973 Ford Ranchero. The Ranchero had a base station sized Pierce-Simpson Guardian radio and an illegal Black Cat linear amplifier. It would really get the signal out.

In those days having a "handle" and special cards to send to "skipland" were the things to do. Here's mine:



From there I moved on to ham radio and am still an extra class to this day though not terribly active currently. Maybe this will change things...

Thanks all for an informative and interesting thread!

1) A NMO mount requires very thin sheet metal to work through. You will have to find a way to mount it just through the sheet metal of the trunk and not the stiffener (possibly big hole in the stiffener and then smaller correct sized hole in the sheet metal?) If you have to go through more than (IIRC) 1/8" of metal, you have to buy a NMO-thick, which can then go through 3/4" or something like that.

2) As far as hitting the garage door, mine does that too. Sounds like the end of the world every time you go in and out. The first time, I was expecting to look up and have a convertible. Any time I do it with other people around, they whip around and look like they think I've run into the house. That being said, I do it all the time with absolutely no damage to the roof, mount, or antenna.

I have my IC-208H under my seat. It's fine when I am sitting with the engine off, but if I'm moving, you can't hear it at all. I bought the largest Uniden Bearcat speaker and mounted it to the "lift to slide seat" bar and it works wonderfully.

R and L Electronics in Hamilton. I started buying stuff from them back in the mid 90s and it still looks the same, but with newer gear on the old shelves. They are real experts.

Yes, I was going to try this method. I don't really mind the looks of the antenna on the roof, but I think the extra noise would drive my wife crazy when I leave for work in the morning.

That's good data! I will see what I can do with the audio. I may dump it to the right rear speaker and see how that works. I have a fire extinguisher in front of the passenger seat and big mag light in front of my seat.

In my WS6 I put the Cobra C19 under the passenger seat (kept it on 19). I could hear everything just fine, and the car was much louder than any other Subaru I have ever owned.

I dusted off my IC-208H and installed it in the wagon today, removing the VHF Kenwood commerical radio. All this talk about mounting radios got me in the mood to change some things around. Pics to follow.

Can a cb expert recomend me a good cb radio and antena for arround 100bucks? I wont be doing a lot of talking on it mainly because I dont travel much on the highway. However it would be nice to talk to some friends in a caravan. I'm not afraid to cut a hole in my trunk for mounting a whip antena.

Links would be nice too. I've been looking at the uniden 520...
Thanks for helping a complete radio nooob out.

The antenna matters more than the radio. Since you're not afraid to make a hole, use a Larsen NMO-K mount, a Larsen NMO-27B antenna (which will have to be cut to the correct length), which will set you back about $60. Then you can get a Midland 1001Z for as low as $25 shipped. Total cost: $85.

If you want to spend a little more money to get a different look on the radio, you can try a Cobra or Uniden radio.

Continued the 2m/70cm install this evening by mounting the chassis of my Kenwood TM-V7A under the passenger seat.

As usual, I went simple:

* a piece of plywood painted black with velco hook on the bottom edges
* an aluminum brace running from the plywood to underneath the right rear seat bolt to hold everything in place
* a quick release bracket for the chassis in case it needs to come out for programming or in-house use

As an unintended bonus, the heat sink ended up in front of the floor vents so I can turn on the A/C to cool things off.
