GME AE4018K2 930mm Elevated-feed Antenna (6.6dbi Gain) - Black

GME AE4018K2 930mm Black Elevated-Feed UHF CB Antenna Kit with Light Duty Spring

The fibreglass-whip equivalent of the AE4012K2, the AE4018K2 is a 930mm elevated-feed UHF CB 477MHz antenna kit combining the black fibreglass and braid copper whip with a light duty stainless steel spring and pre-terminated FME connector, delivering ground-independent performance.

Product overview

The GME AE4018K2 is the fibreglass-whip equivalent of the AE4012K2, an elevated-feed UHF CB 477MHz antenna kit that uses the black fibreglass and braid copper whip rather than a stainless coil whip, with the same light duty stainless steel spring, elevated-feed base, and pre-terminated FME connector as the AE4012K2.

At 930mm total, the AE4018K2 suits the same elevated-feed mounting scenarios as the AE4012K2, including bull bar, gutter, fender, and non-roof positions, while offering the fibreglass and heat shrink construction of the AE4018 whip range. The ground-independent elevated-feed design performs correctly in any mounting position without a steel vehicle ground plane.

The 6.6dBi whip can be swapped for a 2.1dBi option for a broader vertical radiation pattern in hilly terrain.

Features and benefits

Fibreglass whip with black heat shrink: The AE4018B fibreglass and braid copper construction is more impact-resistant than rigid stainless.

Heavy duty braid copper element: A vibration-resistant braided copper internal element.

Light duty stainless steel spring: The same spring type as the AE4012K2, absorbing vibration and allowing the antenna to deflect on impact.

Elevated-feed, ground-independent design: Performs correctly from any mounting position without a steel ground plane.

Pre-terminated FME connector: A quick FME connection, with an AD503 adaptor that may be required for PL259/SO239 radios.

6.6dBi gain: Balanced UHF CB performance for 4WD, heavy vehicle, and fleet use.

Swappable whip: The 6.6dBi fibreglass whip can be replaced with a 2.1dBi option for broader vertical radiation.

Technical specs

Compatible with

The AE4018K2 is compatible with GME UHF CB radios with FME or PL259 input, with an AD503 adaptor that may be required, fibreglass, aluminium, and steel vehicle bodies due to its ground-independent design, and bull bar, gutter, and fender mounting positions.

Frequently asked questions

How does the AE4018K2 compare to the AE4012K2?
Both are elevated-feed kits with a light duty spring, FME connector, and 6.6dBi gain at similar overall length, 930mm compared to 860mm. The AE4012K2 uses a stainless coil whip, while the AE4018K2 uses the AE4018B fibreglass and braid copper whip with black heat shrink. The AE4012K2 also carries a specific diesel vehicle bull bar restriction, which is not mentioned for the AE4018K2. Choose based on whip material preference between stainless and fibreglass.

How does the AE4018K2 differ from the AE4018K1 and AE4018BK1?
The AE4018K1 at 850mm is the no-spring version. The AE4018BK1 at 970mm has a barrel spring. The AE4018K2 at 930mm has a light duty stainless spring. All three use the same black fibreglass whip and elevated-feed base. The spring style and length are the differentiators. Choose the spring version for off-road and vibration applications, and the strength of spring based on the specific installation demands.

What does light duty mean for the stainless spring on the AE4018K2?
A light duty spring has a lower spring rate, deflecting more easily under lighter loads compared to a heavy-duty spring. This makes it more compliant and better at absorbing high-frequency vibration from road and engine sources. A heavier spring would require more force to deflect, which may be more appropriate for extreme off-road use where the antenna may take direct impacts. For most 4WD and fleet applications, light duty is the standard choice.

Can the 6.6dBi whip on the AE4018K2 be swapped for a 2.1dBi option?
Yes. The 6.6dBi fibreglass whip can be removed and replaced with a 2.1dBi whip option, providing a broader vertical radiation angle for terrain where high-gain narrow-angle antennas underperform. Contact us to confirm the compatible 2.1dBi whip SKU.

What connector is on the AE4018K2 cable and is an AD503 adaptor included?
The AE4018K2 uses a pre-terminated FME connector. Whether an AD503 FME to PL259 adaptor is included in the kit is not confirmed in the available source data. Contact us before purchasing if your radio uses a PL259/SO239 antenna input.
