GME AD503 FME Male to PL259 Adaptor
A genuine coaxial RF connector adaptor from GME, the AD503 bridges FME and PL259 connector types, allowing GME FME-terminated antenna cables and accessories to connect to radio equipment using a standard UHF SO239 antenna input.
Product overview
The GME AD503 is a standard FME male to PL259 adaptor that allows GME FME-terminated antenna cables and accessories to connect to radio equipment using a standard UHF SO239 antenna input. The FME male plug end connects to an FME female socket on the cable or antenna accessory, while the PL259 end connects to the SO239 female socket on the radio.
Features and benefits
FME male to PL259: Bridges GME's compact FME connector system with the standard UHF CB/PL259 connector family used across most Australian CB and UHF radio equipment.
Extends FME accessory range to standard radios: Allows FME-terminated cables and GME antenna accessories to connect to radios and equipment with SO239 inputs.
Genuine GME accessory: A manufacturer-supplied adaptor for use with GME FME-connected products.

Frequently asked questions
How does the AD503 differ from the AD501 and AD502?
The AD501 is an FME female adaptor that requires crimping onto coaxial cable using the CTA500 tool, making it a cable termination component. The AD502 is an FME male to BNC adaptor, bridging FME and BNC connector families. The AD503 is an FME male to PL259 adaptor, bridging FME and the standard UHF CB PL259/SO239 connector family. All three are distinct products for different connector bridging scenarios.
Is the PL259 end of the AD503 a male plug or female socket?
PL259 specifically refers to the male plug in the UHF connector family, with SO239 as the female socket. The available source data describes this as an FME male to PL259 adaptor, suggesting both ends are male. Contact us to confirm before purchasing, particularly if you expected a female SO239 end.
What is the typical use case for an FME to PL259 adaptor?
The typical use is connecting a GME FME-terminated cable or antenna lead to a radio with a standard SO239 antenna socket, for example connecting the lead from a GME ABL013 or similar FME marine base to a UHF CB radio's antenna input where the cable terminates in FME but the radio expects PL259. This is common where FME marine antenna systems are paired with standard mobile UHF CB radios.
What GME equipment uses FME connectors?
GME's FME connector is used across the ABL01x marine antenna base range including the ABL012B, ABL013, ABL013B, ABL014, ABL014B, ABL015, and ABL015B, and the ABL002F elevated-feed base. The AD503 bridges these FME-connected products to standard PL259/SO239 radio equipment.
Is the AD503 sold as a single piece?
One adaptor is included per purchase.
