Hey all... I would like to throw in my 2 cents about the CB's.... I would like to suggest Cobra CB's and Francis Antennas.... These are basically plug and play... And the 25 LTD from cobra is very well built for off-road use.... I used one while working in the oil field in Texas and it never failed me!
As for the antenna I suggested, it's a fiber glass rod type and is very rugged and will bend over like a fishing pole before breaking.... With this radio and antenna combo you'll be happy with it and never have to worry about it....
I would also like to suggest getting an external speaker for it.... The stock built in is okay but not very clear.
Here a list of what I think would be more or less the best bang for your buck...
-COBRA 25 LTD
-FRANCIS 4ft. Antenna
-Standard antenna mount and stud
-18ft coax cable
-Decent external speaker
All of this should be about $200....
Shop around you might find everything a lot cheaper.... The above figure is based off buying everything at a truck stop.
Hope this helps a little.
Cheers!!!
