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; the PL259 end connects to the SO239 female socket on the radio.

The AD501 is an FME female adaptor (socket) that requires crimping onto coaxial cable using the CTA500 tool — it is 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.
PL259 specifically refers to the male plug in the UHF connector family (the SO239 is the female socket). The source description says "FME male to PL259 adaptor," suggesting both ends are male — but confirm with GME or your supplier before purchasing, particularly if you expected a female SO239 end.
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.
GME's FME connector is used across the ABL01x marine antenna base range — ABL012B, ABL013, ABL013B, ABL014, ABL014B, ABL015, ABL015B — and the ABL002F elevated-feed base. The AD503 bridges these FME-connected products to standard PL259/SO239 radio equipment.
One adaptor is included per purchase.
