The GME AD407 is a coaxial RF connector adaptor that converts a male TNC plug to a female UHF socket (SO239). It allows equipment or cables terminated with a TNC connector to be connected to a UHF SO239 radio socket or a PL259 plug to pass through to equipment with a TNC input bridging the two connector types without requiring re-termination of the cable.

TNC (Threaded Neil-Concelman) is a threaded coaxial connector used in various RF applications including GPS antennas, some handheld radio antennas, and test equipment. It provides a more secure thread-lock connection than the BNC push-twist connector it derives from. UHF connector (also known as PL259/SO239) is the larger-body coaxial connector standard used in most Australian CB and UHF CB radio equipment — the PL259 is the male plug; the SO239 is the female socket. The AD407 bridges these two connector families.
The TNC plug (male TNC, with an external threaded barrel) connects to the TNC side — for example, a GPS antenna or TNC-terminated cable. The UHF socket (SO239, female) accepts a standard PL259 male plug from a radio or cable assembly.
TNC connectors are found on certain GME GPS antennas, navigation accessories, and some external antenna adaptor assemblies. Confirm whether your specific GME equipment uses a TNC connector with GME or your supplier to verify the AD407 is the correct adaptor.
The AD007 is an FME adaptor for GME AM/FM radios; the AD407 is a TNC to UHF socket adaptor for RF equipment. FME and TNC are completely different connector standards for different applications. They are not interchangeable.
One adaptor is included per purchase.
