The GME AE4018BK1 is a 970mm black elevated-feed UHF CB (477 MHz) antenna kit part of GME's elevated-feed range that provides ground-independent performance in virtually any mounting position. It combines the AE4018B fibreglass black heat shrink whip with an elevated-feed base, a barrel-style black stainless steel spring, and a pre-terminated FME connector.
The elevated-feed design raises the radiating element above the vehicle roof, gutter, or other mounting surfaces to produce a strong omni-directional radiation pattern regardless of mount position suitable for bull bar, gutter, fender, and non-roof installations without a steel ground plane requirement.
The 6.6 dBi fibreglass whip can be replaced with a smaller 2.1 dBi whip option for a broader vertical radiation pattern in hilly terrain.

All three are elevated-feed 6.6 dBi UHF CB kits. The AE4012K2 (860mm) uses a stainless whip with light duty AS001 spring and includes an AD503 adaptor. The AE4017K2 (860mm) uses a stainless coil whip with a parallel polished spring. The AE4018BK1 (970mm) uses the AE4018B fibreglass/braid copper whip with a barrel-style black stainless spring. The AE4018BK1 is the longer, fibreglass-construction option in the elevated-feed family.
A barrel spring has a cylindrical body — it is coiled in a consistent diameter along its length, giving a compact, self-supporting column shape. The parallel spring on the AE4017K2 is a coil spring wound in a parallel (constant pitch) pattern. Both serve the same shock-absorption and deflection function; the barrel spring's more compact form factor keeps the overall antenna profile narrower where it meets the base, while the parallel spring is typically more compliant over its full length.
Yes — the source description confirms the 6.6 dBi whip can be replaced with a smaller 2.1 dBi option for a broader vertical radiation pattern. This is the same swappable-whip feature as the AE4012K2. A compatible 2.1 dBi GME whip (such as the AE4001 or AE4002) would be used — confirm compatibility with GME.
The AE4018BK1 uses a pre-terminated FME connector. If the radio uses a PL259/SO239 input rather than FME, an AD503 FME to PL259 adaptor will be required. Confirm whether the AD503 is included in the kit with GME before purchasing.
Unlike the AE4012K2, AE4017K1, and AE4017K2, the AE4018BK1 source description does not carry the diesel vehicle bull bar restriction. However, as a general principle for all elevated-feed stainless whip antennas, caution around diesel engine bays is advisable — confirm with GME if your vehicle is diesel.
