GME AE2001 320mm Black Rubber 27MHz CB Antenna Whip A pre-tuned 320mm black rubber whip antenna from GME, the AE2001 is designed for 27MHz CB radio use with a ground-dependent design suited to steel-bodied vehicles. Whip only, sold individually. Product overview The GME AE2001 is a 320mm black rubber whip antenna for 27MHz CB radio, part of GME's pre-tuned 27MHz antenna range. Available in a variety of lengths and styles, the AE2001 offers a compact 320mm form factor suited to installations where a full-length whip is not practical. The AE2001 uses a ground-dependent design, relying on the vehicle's metal body as a ground plane for optimal antenna performance. It is not suited to fibreglass, aluminium, or non-metallic vehicle bodies without a ground-independent elevated-feed antenna or NGP base. Whip only. The antenna base, coaxial cable, and radio are not included. A compatible 27MHz antenna base is required separately. Features and benefits 320mm black rubber whip: A compact flexible rubber antenna suited to installations where a shorter 27MHz antenna is preferred. Pre-tuned for 27MHz: Factory-tuned for use on the 27MHz CB band, requiring no adjustment. Ground-dependent design: Uses the vehicle's metal body as ground plane, requiring a ferrous steel mounting surface for correct antenna performance. Whip only: No base, cable, or radio included. A compatible 27MHz antenna base is required separately. Technical specs Specification Detail SKU AE2001 Brand GME Type 27MHz CB Antenna Whip Length 320mm Style Black Rubber Whip Design Ground Dependent Frequency 27MHz (CB) Includes Whip Only Compatible with The AE2001 is compatible with 27MHz CB antenna bases with the correct thread, GME 27MHz CB radios, and steel-bodied vehicles where a ground plane is available for the ground-dependent design. Confirm thread compatibility with us before purchasing. Frequently asked questions What antenna base is compatible with the AE2001?Thread type is not confirmed in the available source data. Contact us to confirm which thread standard the AE2001 uses and which GME antenna bases, such as the ABL001 with 5/16" TPI thread, are compatible. What does ground dependent mean for this antenna?A ground-dependent antenna relies on the vehicle's metal body to form the electrical ground plane, the reflective surface that allows the antenna to radiate correctly. On a standard steel-bodied vehicle, the roof or bonnet provides this ground plane. On fibreglass, aluminium, or other non-metallic surfaces, the antenna will not perform correctly without an elevated-feed ground-independent base such as the GME ABL002. Why is the AE2001 only 320mm for a 27MHz signal?A full quarter-wave antenna at 27MHz would be approximately 2.7 metres, far too long for most vehicle installations. The AE2001's 320mm physical length is achieved through an internal loading coil, which electrically lengthens the antenna to near-resonance at 27MHz while keeping the physical size compact. This trades some efficiency for practicality in installations where a 2.7m whip is not feasible. What does pre-tuned mean for the AE2001?Pre-tuned means the antenna has been factory-adjusted for the 27MHz CB frequency. Unlike some antennas that require trimming or adjustment at installation to achieve correct resonance, the AE2001 is ready to use without modification. Is a base or cable included with the AE2001?No. The AE2001 is a whip only. A compatible antenna base, coaxial lead, and radio are purchased separately. Confirm the thread type with us when selecting a compatible base.
