The AE470x series is an adaptable UHF CB antenna system with a range of spring bases and user-interchangeable whips. This allows you to quickly and easily switch between whips to suit the operating conditions and application. The AE470x series includes a range of shorter length whips with lower gain for mountainous terrain or built-up areas, and longer length whips with higher gain for travelling on open roads or flat terrain. The AE4704B is a popular choice for the 4WD enthusiast requiring a robust antenna for hardcore off-roading or touring. Also available in White (AE4704).
