GME ABL017B Black Elevated-Feed Antenna Base with Delryn Construction and PL259 The black version of the GME elevated-feed antenna base and lead assembly, the ABL017B uses high-quality Delryn acetal plastic construction with a black ferrule, ground-independent elevated-feed design, 4.5 metres of low-loss foam coaxial cable, a PL259 plug, and a BSW thread. Product overview The GME ABL017B is the black version of the GME elevated-feed antenna base and lead assembly. It uses the same ground-independent elevated-feed design as the ABL017, meaning the antenna does not require a flat metal vehicle roof for ground plane and can be mounted on brackets, aluminium, fibreglass, or other non-metallic surfaces. The ABL017B is constructed with a black ferrule and high-quality Delryn acetal plastic rather than the polished silver stainless steel of the ABL017. The kit includes the elevated-feed assembly, 4.5m of low-loss foam coaxial cable, and a PL259 plug, providing a complete ready-to-install assembly. The BSW thread is consistent with the ABL017 and the rest of the GME elevated-feed base range. The polished silver stainless steel version of this base is the ABL017. Features and benefits Black finish: Suited to vehicles and installations where a black antenna base is preferred, with a black ferrule throughout. High-quality Delryn acetal plastic construction: Delryn is an engineering thermoplastic known for its strength, dimensional stability, and moisture resistance, suited to outdoor and vehicle applications. Ground-independent elevated-feed design: Allows antenna mounting beyond the vehicle roof, including on bull bars, brackets, and non-metallic surfaces, with no flat metal ground plane required. BSW thread: Confirm your antenna uses a BSW thread before purchasing. PL259 plug included: A standard radio connector supplied in the box, connecting directly to radios with an SO239 input. 4.5m low-loss foam coaxial cable: Minimises signal attenuation over the full cable run. Polished silver version available: The ABL017 is the stainless steel equivalent of this base.

Confirm your antenna uses BSW thread before purchasing. Suits radios with an SO239 antenna socket, accepting the included PL259 plug. Compatible with mounting brackets, aluminium, fibreglass, and non-metallic vehicle surfaces across 4WD, marine, and recreational installations where ground-dependent bases are not suitable. Frequently asked questions How does the ABL017B differ from the ABL017?Both are elevated-feed bases with ground-independent design, BSW thread, 4.5m low-loss foam coax, and PL259 connector. The ABL017 is constructed in polished silver stainless steel. The ABL017B uses black Delryn acetal engineering plastic with a black ferrule. The Delryn construction is lighter than stainless and still suited to outdoor vehicle use, while stainless provides superior corrosion resistance in particularly harsh marine or coastal environments. What is Delryn plastic?Delryn, also known by the DuPont trade name Delrin, is an acetal resin engineering thermoplastic offering high stiffness, low friction, good dimensional stability, and resistance to moisture, fuels, and solvents. It is commonly used in automotive and outdoor accessory hardware where metal components would be heavier or less practical, providing a durable, weather-resistant construction for vehicle-mounted antenna applications. What does elevated-feed mean and why does it make the base ground independent?An elevated-feed base positions the antenna's electrical feed point away from the mounting surface, incorporating a built-in counterpoise into the base itself rather than using the vehicle body as the ground plane. This is in contrast to a standard antenna base which relies on a flat metal vehicle roof to form the antenna's ground plane. The elevated-feed design means the ABL017B works correctly on bull bars, brackets, fibreglass, aluminium canopies, and any other mounting location without needing a flat metal surface below. Does the ABL017B include a mounting bracket?No. The ABL017B includes the elevated-feed base assembly, 4.5m coaxial lead, and PL259 plug only. Any vehicle-specific or universal mounting bracket, such as a bull bar mount, gutter clamp, or bonnet bracket, is purchased separately. Is the PL259 connector specific to GME or a universal standard?PL259 is a universal industry-standard coaxial connector used across CB, UHF, and amateur radio worldwide. The included PL259 plug connects to any radio with a standard SO239 female antenna socket, covering the vast majority of Australian CB and UHF mobile radios. It is not GME-proprietary.
