Get one of the Generals. Not cheap but with SWTR settings and power settings and so on the radio. Get ten meter but use it only on CB bands. You go to Mexico and South America you can turn it full power. I would get a stainless full wave antenna. It will have to be ground plan or maybe they can make it work with a small piece of metal. It doesn't have to stand straight up but it helps. It can be clipped down on the long end closer to the body.
You have to watch CB shops at Truck stops. Most of those kids know how to blot one on and tune it on a truck but are pretty much clueless about Mhs. Use the net and ask around for one that can get it performing well.
There's been a great many times we/ve needed the CB approaching cities or traffic off in the distance. The new problem is Truckers don't keep them on as much as before so not as much active reporting on the road ahead. A good whip antenna up high like that with full five watts or 10 watts or 100 watts will reach way out there and amplify signals coming in so you can hear most of them.
Five watts out is the limit legally though and all I run on my 35 year old Teaberry.
