ANSI SCTE 146-2017 pdf download.Outdoor “F” Female to “F” Female Inline Splice
1.1. Scope
The purpose of this document is to recommend mechanical and electrical standards for 75 ohm broadband radio frequency (RF) devices whose purpose is to provide an outdoor inline connection between two type “F” male connectors that conform to ANSI/SCTE 123; Specification for “F” Connector, Male, Feed- Through or ANSI/SCTE 124; Specification for “F” Connector, Male, Pin Type and ANSI SCTE 160, Specification for Mini F connector male Pin type. The mechanical configuration is designed to accommodate sealing rings for external applications. This specification is not intended to restrict any manufacturer’s innovation and improvement. The specification may be amended in the future as deemed appropriate.
