So i just stopped in RadioShack the other night while i was waiting for my Chinese food. and i happened to see that they have a cb radio for only $49....i thought about it and thought it could be kinda cool to have one....if i mounted it in my glove compartment that wouldnt be obvious out in the open...my only question is the antennae. would it be possible to pull down my radio antennae and run the cb radio in its place?
