ANSI SCTE 155-2017 pdf free download – Indoor “F” Female to “F” Female Inline Splice.
The purpose of this document is to recommend the mechanical and electrical standards for 75 ohm broadband radio frequency (RF) devices that provide an indoor inline connection between two type “F” male connectors that conform to ANSI/SCTE 123 2011, Specification for “F” Connector, Male, Feed- Through or ANSI/SCTE 124 2011, Specification for “F” Connector, Male, Pin Type. The mechanical configuration is designed to accommodate wall plate and bulkhead 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.
