Frequently asked questions What are TNC and UHF connectors?TNC (Threaded Neil-Concelman) is a threaded coaxial connector used in various RF applications including GPS antennas, some handheld radio antennas, and test equipment, providing a more secure thread-lock connection than the BNC 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, with the PL259 as the male plug and the SO239 as the female socket. The AD407 bridges these two connector families. Which end of the AD407 is which?The TNC plug, 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. What GME equipment uses TNC connectors?TNC connectors are found on certain GME GPS antennas, navigation accessories, and some external antenna adaptor assemblies. Contact us to confirm whether your specific GME equipment uses a TNC connector before purchasing. How does the AD407 differ from the AD007 FME 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 and are not interchangeable. Is the AD407 sold as a single piece?One adaptor is included per purchase.
