GME AE4005 380mm Flexible Antenna (2.1dbi Gain)

GME AE4005 380mm Flexible UHF CB Antenna Ground Independent with M10 Stud Mount

A complete 380mm flexible UHF CB antenna kit from GME, the AE4005 uses a ground-independent design suited to fibreglass, aluminium, and non-metallic surfaces, with an M10 stud mount, 4.5 metres of coaxial cable, and a PL259 plug included.

Product overview

The GME AE4005 is a 380mm flexible black heat shrink UHF CB 477MHz antenna with 2.1dBi gain. Unlike the ground-dependent AE4001 and AE4002, the AE4005 uses a ground-independent design, meaning it does not require a steel mounting surface to form the antenna ground plane, making it suitable for fibreglass, aluminium, and non-metallic vehicle and vessel bodies.

The AE4005 uses an M10 stud mount, which installs through a drilled hole and is secured with the included M10 nut. The kit includes a 4.5m coaxial cable and PL259 plug, GME part number PL2592S, a complete installation package.

Features and benefits

Ground-independent design: No steel body required, suitable for fibreglass, aluminium, and non-metallic surfaces.

380mm flexible black whip: Flexible rubber and composite construction with black heat shrink, more impact-resistant and flexible than rigid stainless.

M10 stud mount with nut: Installs through a drilled hole, with the M10 nut securing the antenna base from below.

2.1dBi gain: Standard UHF CB baseline gain with a wide vertical radiation angle.

4.5m coaxial cable included: A ready-to-route cable for most vehicle and vessel installations.

PL259 plug (PL2592S) included: The standard UHF CB radio connector supplied in the kit.

Complete kit: Antenna whip, coaxial cable, and PL259 plug all included.

Technical specs

Compatible with

The AE4005 is compatible with UHF CB radios with PL259/SO239 antenna input, fibreglass, aluminium, and non-metallic vehicle and vessel bodies due to its ground-independent design, and steel-bodied vehicles as well.

Frequently asked questions

What does ground independent mean for the AE4005?
Unlike ground-dependent antennas such as the AE4001 and AE4002 that rely on the vehicle's metal body to form the electrical ground plane, the AE4005 uses an elevated-feed design that generates its own counterpoise. This means it performs correctly on fibreglass, aluminium, and non-metallic vehicle bodies, not just steel-bodied vehicles. It is also fully compatible with steel bodies.

What is an M10 stud mount?
An M10 stud mount is a through-hole mounting style. A hole of approximately 10mm diameter is drilled in the mounting surface, the antenna stud is inserted from above, and the included M10 nut secures it from below. This is a permanent installation method that provides a very secure, low-profile mount compared to magnetic or gutter clip mounts.

How does the AE4005 compare to the AE4001 and AE4002?
The AE4001, natural stainless, and AE4002, black heat shrink stainless, are compact 150mm rigid whips that are ground dependent, whip only, with a thread-based base rather than stud mount. The AE4005 is 380mm, flexible, ground independent, uses an M10 stud mount, and is a complete kit including cable and PL259 plug. The AE4005 is more appropriate for non-metallic bodies and installations where a flexible, through-hole mounted antenna is preferred.

What does flexible mean for the AE4005 whip?
A flexible whip is constructed from a flexible rubber or composite material rather than rigid stainless steel. This makes it more resistant to impact damage, as the whip bends and recovers rather than breaking on contact with obstacles. It is well suited to off-road, bush, and tight-clearance environments.

Does the AE4005 kit include everything for installation?
Yes. The AE4005 kit includes the flexible antenna whip, 4.5m coaxial cable, and PL259 plug. An M10 hole is required in the mounting surface, approximately 10mm diameter. A UHF CB radio is not included. No additional base, thread adaptor, or separate cable purchase is required.
