Your CB antenna should be minimum just high enough to clear your building. Now for the tech stuff CB modulation is carried over a "wave". You only can get one wave out of your antenna unless you put it ABOVE 75ft then you can get your second wave hence farther/stronger signal. So the answer is yes higher does help but you have to go above 75ft for it to help and good luck with zoning laws. Now you could use a Directional antenna for longer jumps.Does putting your antenna really high up help with reception? If your at a house and want to reach people 3 miles away on the freeway would this work?
Cb is great if your near populated areas, interstates, etc. Cell phones are going to be useless if the shtf. Ham radio offers more in the way of reliable communications, greater range, clarity, less bs.Anyone have thoughts on modern uses for CB radios? Beyond the use by truck drivers.....how could a CB radio aid the average person?
