A new line of specialized interface adapters and connectors achieve FCC Part 15.203 compliance in three different ways. First is reverse polarity, or gender; second is reverse, or left-handed threads; and third is the use of metric rather than Unified Standard threads. The reverse thread method is used in the RT-1203-1X TNC plug with left-handed threads. This 50-_ connector is designed for use with RG-8/X or LMR-240 low-loss cable and has a nickel-plated, machined brass body, Teflon insulation and gold-plated contact. Other styles are available using the three methods above. For more details and prices,XS contact RF CONNECTORS DISTRIBUTORS, San Diego, CA. (800) 233-1728.
