krazykracker is right about inexpensive radios y Uniden, they are usually good enough.
Antennas, I like Wilson, I will be mounting a Trucker 5000 on the rear tire holder with an extended lower mast about 18"s. The extended mast will get the coil even or above the top where I like it. The top mast is a very flexible whip about 36" long but a shorter whip is available but I think it has an added coil in it; too many coils to snap.
Good Luck, everyone has their favorite, look and listen to friend and see what they are running and if you like how their antenna performs then buy it, at least until you have tried a few and determined which one you really like.
Do it right the first time !
