OK so i want to buy a new CB and I'm looking at some online and i see 10 meter and 11 meter, whats the difference? and is there anyway to amplify the CB's signal?
10 meter's is a HAM radio band. CB falls into the 11 meter bandwidth. You can jack with a 10m radio and get it to work on the CB frequencies (at 10m power), but I do not think that is where you want to go.
Buy a good radio (Uniden, Cobra, Galaxy, etc) that has the form factor and features you want from a good dealer. Get a "tweak and tune" on a stock radio, buy a good antenna/mount and get your SWRs matched and you will have a good rig.
I like Bell's CB shop (not the best prices but I trust them), but there are many good ones. There are also many bad ones out there that will butcher a perfectly good radio doing a "tweak" so you might want to do a little research on the shop you choose.
