CB radio

Planning my first caravan and a CB radio was mentioned. Does anyone use one in their interstate? Does it plug into 12 volt? Is a magnetic antenna required or can I use current antenna. If so, where is it connected. From Amazon photos, it looks like it screws into cable like outlet. THANKS

FYI the CB/Ham sub-forum may be helpful IMO:

Also these search results: https://www.google.com/search?q=ham+...com&gws_rd=ssl

Happy trails,

I bought a CB radio because the Cajun Country Caravan information said one would be used for communication. They did not use CB on the caravan. Check with your caravan leaders before spending the money.

You can receive with any antenna. To transmit you need a CB antenna. A large truck stop is a good place to look at and purchase a radio. Some caravans use them a lot. Some do not. Al’s suggestion to check with the leaders is good. Some folks like to travel together and use the radio on travel days. I mounted a antenna on my TV.

My suggestion is to go ahead and work out how you want to carry or mount a radio and get one. I hate the thing. But it is in a good place in the truck and I turn it on when on a caravan.

CB is great for vehicles traveling together. Find an unused channel and everyone goes there. Listening to truckers is entertaining....for about 5 minutes.
I keep it simple, CB radio, 12v. lighter plug for power, mag mount antenna. Plop it on the roof and go.

I didn't want anything big ...looked at Midland75-822 hand held, but reviews mixed and I guess you have to pair the magnetic antenna and it sounds like that doesn't always go well. I might buy something right before, keep in box, see if it will be part of the caravan, and if so, have someone in the group help me get it set up. And if it's not part of the travel, send it back.

Did you have to sync the antenna with the unit?

Yes. The radio works best when tuned to the antenna. Tune your radio to channel 20 and key the mic. You are looking for the lowest SWR (standing wave ratio?) - 1.5 or lower is your target. Read the instructions that come with the antenna to learn how to tune it. Also, there are lots of videos available. Not hard at all.

I have always had issues trying to hear someone with a hand held cb. I would vh o with a simple setup which you can find at any truck stop.

Traveling on a caravan is always better with a cb.

The one I bought (and didn't use) was a handheld with an adapter to hook up to external power and antenna. I bought two adapters and two antennas, a set for the truck and a set for the trailer. The truck antenna is a mag mount I only put up when I anticipate using the CB (never). The trailer antenna is mounted on an angle bracket under the top retaining bolt for the roadside segment protector. I ran acoax cable out through the hole in the floor for all the DC cables.

Our car club uses inexpensive FRS handhelds, but everyone has to have one and they are only good if you can see the other vehicle. CB carries a little better.

Our group uses FRS Radios and have no issues with the good ones. The cheapo's can be a bit garbled. The one's that work best for us are the Midland - X-TALKER T77VP5. They have decent range and are the clearest communication, (both ways) One tip, using the supplied rechargeable battery pack gets you about a day of use. Using 3 Double A alkaline batteries gets you about a week.

I believe you have to tune the antenna to the surface it is mounted on. Otherwise you may blow a power transistor in the CB
You also need to mount the antenna so it can see behind your trailer. otherwise you may not get good reception from those following you.
My 2 cents; just some things I've picked up along the way....no way am I an expert on this one.

I have cb since early 60s when had to have lic. Have talked skip all over world. I have had 50ft tower antennas, base radios w/side band hand also hand held D104 microphone on base. Old days ran outlawed high power, all kinds mobile antennas. IMO use mag mount on roof and cheap radio w/plug in cig. lighter for caravans, don't spend lots of money unless use lots. As far as prev. poster you will not blo any thing in radio unless hook up 12v radio to 110v or any to 220v. In many yrs. never did any thing but plug and play, all kinds mobile antennas including doubles [one on each mirror on truck], I now have mag mount on roof and inexpensive radio plug in cig. lighter & use very little & never had or used hand held. I have heard all kinds of so called experts spout what or if but none have facts, as far as adj. any forget it. Lets hear form ham radio guys chime in they are experts as there are many on forum. I only no about my experience of many yrs.

I've been away from CB for a long time but I don't think you can "tune" the antenna, it's more about where you put it. A full wave, 108" antenna or (base/center) loaded antenna will work. The SWR (yes, standing wave ratio) measures the reflectivity of the signal. The metal of the vehicle is the base/ground portion, whether the antenna is bolted or magnetic. The antenna does the broadcasting. If mounted on the center of the roof then there is minimal reflection of the signal and the broadcast area is a circle around the antenna mast and the car. If mounted on the rear bumper the signal will tend to go more forward and less to the rear and there will be some reflectivity from the top of the car back to the antenna.

With the AS connected you get a larger base and if you have a tall antenna (higher than the AS) then you get a very good signal. A shorter antenna will give you more reflectivity so you'd want to have the antenna more to the front of the car.

Unless you want to purchase a separate SWR meter, just place the antenna (magnetic is fine for this limited use) in the center of the car or even a little forward. Find a place where you can run the cable into the car from the outside. Through the door will work OK if you don't open that door a lot or you'll break the cable by metal fatigue if you do. Connect the cable to the CB and plug the CB into the cigar lighter unless you want a permanent connection. Ideally, a ground between the CB and the car will give the clearest transmission.

This is probably more than you wanted to know, a disease I seem afflict me.

Still have it but relegated to shelf collecting dust. What you stated about antenna & swr very true, also some antennas can be trimmed for swr.
