"Eleven meter "Facts and Fallacies" (they are hard to tell apart): The more watts to the antenna, the better your chance of being heard; counter argument, too many watts for a given distance (close) will be beat by less watts because the higher powered signal is over-shooting the target."
CB is laugh city and this is no exception. There is no such thing as too many watts overshooting the target, have you ever heard of a shootout? That's when mobiles gather in a parking lot or field, set up monster antenna arrays on the roofs of their vehicles and two line up to shoot at a target vehicle downrange. The loudest signal wins, that is to say the one who stomps on the other. Of course there are super power amps and heavy duty alternators driven at high RPM by hemi engines, sometimes sparks fly and antennas go into melt down.
I couldn't find the video I was looking for but you might find this interesting. Notice the herringbone pattern caused by the intense RF field:
