A genuine coaxial RF connector adaptor from GME, the AD504 bridges FME and TNC connector types, allowing GME FME-terminated cables and accessories to connect to equipment using TNC connectors such as GPS antennas, marine electronics, and RF test equipment.
The GME AD504 is a standard FME male to TNC adaptor that allows GME FME-terminated cables and accessories to connect to equipment using TNC connectors, such as GPS antennas, certain marine electronics, and RF test equipment. The FME male plug end connects to an FME female socket on the cable or GME accessory, while the TNC end connects to TNC-terminated equipment.
FME male to TNC: Bridges GME's compact FME connector system with TNC-connected equipment including GPS antennas, marine electronics, and RF accessories.
Genuine GME accessory: A manufacturer-supplied adaptor for use with GME FME-connected products.

How does the AD504 differ from the AD407 TNC to UHF adaptor?
The AD407 is a TNC plug, male TNC, to UHF socket, female SO239, adaptor, with a TNC male plug on one end and a standard UHF SO239 socket on the other. The AD504 is an FME male to TNC adaptor, with FME male on one end and TNC on the other. They address different connector bridging scenarios: the AD407 connects TNC equipment to UHF radio inputs, while the AD504 connects FME equipment to TNC-connected accessories.
Is the TNC end of the AD504 male or female?
The gender of the TNC end is not confirmed in the available source data. Contact us before purchasing to confirm.
How does the AD504 fit into the GME AD5xx FME adaptor series?
The AD5xx series covers GME's range of FME-based adaptors: the AD501 with FME female crimp termination requiring the CTA500, the AD502 with FME male to BNC, the AD503 with FME male to PL259, and the AD504 with FME male to TNC. Each adaptor bridges FME to a different connector family for different equipment pairings.
What is the typical use for an FME to TNC adaptor?
A common use is connecting a GME FME-terminated marine antenna lead to a GPS antenna or marine electronics device that uses a TNC connector. TNC connectors are found on certain GPS antennas, AIS equipment, and RF test gear. Where the cable terminates in FME but the device requires TNC, the AD504 bridges the gap.
Is the AD504 sold as a single piece?
One adaptor is included per purchase.
