Compact. Rugged. Interchangeable. GME AE4707B UHF CB Antenna for Remote 4WD Touring.

Product Overview

The GME AE4707B is a 595mm medium duty fibreglass radome UHF CB antenna delivering 2.1dBi gain in a compact, robust package engineered for 4WD enthusiasts heading into Australia's outback. Part of the GME AE470x series an adaptable UHF CB antenna system the AE4707B pairs a black fibreglass radome whip with a medium duty spring base and an interchangeable whip design, allowing you to swap between whips to match conditions without changing the base or wiring.

At 595mm with 2.1dBi gain, the AE4707B is a shorter, lower-gain whip suited to mountainous terrain, built-up areas, and dense bush where a taller, higher-gain antenna risks damage or creates clearance issues under low branches and between rocks. The ground independent design means it performs without requiring a ground plane suitable across vehicles, bull bars, roof racks, and non-metallic mounting surfaces. Pre-terminated with an FME connector for direct connection to compatible GME UHF CB radios.

Features & Benefits

• Interchangeable whip — switch to suit the terrain — The AE470x series design allows the whip to be removed and replaced with other AE470x-compatible whips without changing the spring base or rewiring. Heading into tight bush or mountainous terrain? Swap to a shorter, lower-gain whip. Back on the open highway or flat outback plains? Switch to a longer, higher-gain whip. One base, multiple configurations.
• 2.1dBi gain — the right choice for challenging terrain — At 2.1dBi, the AE4707B delivers effective UHF CB communication without the height and gain of longer whips that can cause problems in dense scrub, rocky terrain, and under low creek crossings. Lower gain at shorter length means more forgiving signal radiation patterns — appropriate where antennas need to deal with obstacles rather than optimise for flat open road.
• Medium duty spring base — protection without compromise — The medium duty spring absorbs impacts from low-hanging branches, garage door frames, and trail obstacles — deflecting the antenna rather than transferring the impact force to the mount or vehicle body. Built for the real-world encounters that happen on any serious 4WD track.
• Ground independent design — mount anywhere — No ground plane required. The AE4707B operates correctly on bull bars, roof racks, non-metallic canopies, and fibreglass bodies — opening up mounting locations that ground-dependent antennas cannot use effectively. Critical for modern 4WD builds with aluminium and composite bodies.
• Black fibreglass radome — durable and low-profile — The fibreglass radome protects the radiating element from physical impact, UV exposure, and Australia's harsh outback conditions — red dust, heat, corrugations, and water crossings. The black finish is low-visibility and consistent with factory and aftermarket 4WD aesthetics.
• Pre-terminated FME connector — plug-and-play installation — Factory-terminated FME connector connects directly to compatible GME UHF CB radios and FME-equipped accessories without on-site termination. Clean, reliable connection without the variables of field crimping.
• Part of the AE470x series — adaptable system — The AE4707B whip is one component of the GME AE470x antenna system. Additional spring bases, whips of different lengths and gain ratings, and mounting accessories are available within the range — allowing the system to be expanded or reconfigured as your 4WD setup evolves.

Frequently Asked Questions

What does 2.1dBi gain mean and when is it the right choice?

Gain measures how much the antenna focuses signal in a particular direction compared to a reference antenna. At 2.1dBi, the AE4707B has a wide radiation pattern suited to hilly terrain, dense bush, and built-up areas where signal needs to reach nearby vehicles in multiple directions. Higher-gain antennas focus signal more narrowly toward the horizon — better for flat, open terrain but less effective in broken terrain.

Can I use the AE4707B whip with a different AE470x spring base?

Yes — the AE470x series uses interchangeable whips across compatible spring bases. This allows you to use the AE4707B compact whip on a heavy duty base for maximum mount protection while retaining the compact whip for tight terrain. Confirm whip-to-base compatibility across the AE470x range with GME before mixing components.

Does the AE4707B require a ground plane to work correctly?

No — the ground independent design operates correctly without a metal ground plane beneath the antenna. This makes it suitable for mounting on bull bars, aluminium roof racks, fibreglass canopies, and other non-metallic surfaces found on modern 4WD builds.

What FME connector is on the AE4707B and which radios does it suit?

The AE4707B is pre-terminated with an FME connector. Most GME UHF CB radios use FME antenna connections, making this a direct plug-in with compatible GME radio models. Confirm your specific radio's antenna socket type before purchasing — an FME adaptor may be required for non-FME radios.

When should I choose the AE4707B over a longer, higher-gain antenna?

Choose the AE4707B when you're travelling through mountainous terrain, dense scrub, or areas with overhead obstacles — where a shorter antenna reduces the risk of damage and 2.1dBi provides appropriate communication range for the environment. On open highways and flat outback plains, a longer AE470x whip with higher gain will deliver greater communication distance.
