Not easily.
Yes, you want to get the SWR, not very expensive and vital to tuning the CB for good reception. Its a hassle, but WELL worth the time, when you have a 3+ mile range on your CB. Excellent for on the road driving to hear the trucker chatter (entertainment) and for the off highway travel to communicate with others. Its helped out on quite a few runs I have had, especially when having to escort a broken rig back to town and finding another group, or meeting up with the Gold Bar Rim crew when running Golden Spike.

Do not meddle in the affairs of dragons for you are crunchy and taste good with ketchup.
