Dont buy a cheap radio. The president lincoln ii plus is a very good radio. And get a Stryker A10 antenna. You will need to go to your local cb radio shop. Or check out http://www.rrcom.com/ and call them or https://www.bellscb.com/
I always deal with R&R communication in the state of Delaware.
I use both gmrs and cb in my car..
I hope this well help you out.
