How to Choose CB Radio Antenna

Antenna is playing big role to give best result of two way cb radio communication. Even you use good cb radio, but you use bad cb antenna, your two way communication quality will be disappointed. In same manner, if you use cheap cb radio but use good cb antenna, you will get satisfaction during your two way radio communication.
To choose a good cb antenna, first you have to know about what kind of metal used on antenna construction. Better metal position on Volta list means better conductivity. So it will radiate more energy to air (and not send it back to your cb radio resulting a high VSWR value).
Second, lower take off angle means good long distance range while higher angle means good two way local radio communication.
Third, the longer the whip (for whip CB antenna), the better result will get. Most of factory made whip CB antennas are consist of a whip and a coil. Since the wavelength is 11 meters, the normal whip long will make your car or truck look like "Lunar Module". So antenna factories offers some models with reducing the whip length. Just remember this, shorter whip mean shorter range.
Fourth, higher the antenna gain is better. It's simple to see this. Just check on antenna cover. And compare your CB antenna candidate with others. Gain value is a number indicating how much your radio energy will be amplified on air. So if the gain is high, radio energy will increase and will make sure a succesful of a two way radio communication.
