The AE4700 series is an adaptable antenna system with the coaxial termination embedded within the spring assembly with easy screw down fit of the whip. This allows for interchange ability of whips depending on the operating conditions and application, shorter lengths and lower gain for hilly terrain and longer lengths with higher gain for travelling on open roads with flat terrain. The ability to remove the whip and cover with a protective cover (included in the pack) allows the whip to be taken off if not required. These antennas are a popular choice for 4WD caravans and heavy vehicles.
