Any body here into cb radios? I'm about to buy one just trying to get it all figured out. Is it worth the extra money to buy like a cobra 29lx or would me cheaping out and getting a uniden 505 be ok. I'd really like one with the weather on it but it is Not a deal breaker since I usually have another radio of some kind on me. Also can you tune your antenna yourself or will I have to take it to a cb shop.
