Don't get a CB mate, they have no range. You would probably be better off shouting to the person. If you lived in town they would be alright, but you live in the country among trees and probably hills, and the power of a CB just does'nt cut it in my opinion.
You don't need to run one of those massive wanka ariels. Just get a nice little neat GME metal one. Thats what i have on my ute, and its the same as yours. Its only about 50cm long and it gives the UHF plenty of range.
Just get a decent GME set and be done with it, yes i know they are a little pricey, but you wont regret it, and they last for ages.
I have got a GME TX3800. Recommended!
