GME AE4001 Compact 150mm UHF CB Antenna Whip 2.1dBi Stainless Steel A compact 150mm stainless steel UHF CB 477MHz antenna whip from GME, the AE4001 delivers 2.1dBi gain with a polished stainless steel ferrule and ground-dependent design, suited to installations where a low-profile short-length UHF antenna is required. Whip only, sold individually. Product overview The GME AE4001 is a compact 150mm stainless steel UHF CB 477MHz antenna whip with 2.1dBi gain. The first UHF CB whip in GME's AE4xxx antenna range, the AE4001 suits installations where a low-profile, short-length UHF antenna is required. The polished stainless steel ferrule provides a clean, corrosion-resistant connection point. This is a ground-dependent design, requiring a steel mounting surface to form the antenna ground plane. The AE4001 is a whip only. An antenna base and coaxial cable are required separately. Features and benefits 150mm compact UHF CB whip: A low-profile stainless steel whip suited to installations where antenna height must be minimised. 2.1dBi gain: Baseline UHF CB gain, equivalent to a standard dipole reference antenna. Stainless steel construction: Corrosion-resistant and durable for long-term outdoor use. Polished stainless steel ferrule: The connector and base fitting is polished stainless steel for appearance and corrosion resistance. Ground-dependent design: Requires a ferrous steel mounting surface to provide the antenna ground plane. Whip only: Antenna base and cable are purchased separately. Technical specs Specification Detail SKU AE4001 Brand GME Type UHF CB Antenna Whip (477MHz) Length 150mm Gain 2.1dBi Construction Stainless Steel with Polished Stainless Ferrule Design Ground Dependent Includes Whip Only Compatible with The AE4001 is compatible with UHF CB antenna bases with the correct thread, GME UHF CB radios (477MHz), and steel-bodied vehicles and vessels where a ground plane is available for the ground-dependent design. Confirm thread compatibility with us before purchasing. Frequently asked questions What does 2.1dBi gain mean for a UHF CB antenna?Antenna gain in dBi is measured against an isotropic theoretical perfect omnidirectional reference. 2.1dBi is effectively equivalent to a half-wave dipole antenna, the baseline for UHF CB performance. It radiates relatively evenly in all horizontal directions. Higher gain antennas such as 6.6dBi or 9dBi concentrate radiation closer to the horizon for greater range in flat terrain, but 2.1dBi provides a wider vertical radiation angle that may be more useful in hilly terrain or on vessels. What is the ferrule on the AE4001 and why is it important?The ferrule is the metal fitting at the base of the whip that provides the mechanical and electrical connection between the whip and the antenna base. A polished stainless steel ferrule resists corrosion in marine and coastal environments and provides a secure, clean connection to the base thread. What antenna base is compatible with the AE4001?Thread type is not confirmed in the available source data. GME's standard UHF CB antenna bases such as the ABL001 at 5/16" TPI may be compatible, but confirm the AE4001's thread specification with us before purchasing a base. The AE4001 is part of GME's UHF CB antenna range which typically uses 5/16" TPI or similar standards. How does the 150mm AE4001 compare to a longer UHF CB antenna?At 150mm, the AE4001 is significantly shorter than most UHF CB antennas. A standard quarter-wave at 477MHz is approximately 157mm, so 150mm is near-resonant but compact. Shorter antennas have a lower physical profile and are less prone to damage in low-clearance environments, but may have a marginally different radiation pattern compared to optimised longer designs. Higher-gain longer whips such as 6.6dBi would provide better range on flat terrain. Is a base and cable included with the AE4001?No. The AE4001 is a whip only. An antenna base, coaxial lead, and radio are all purchased separately.
