ANSI/SCTE 160 2010
Specification for Mini ‘F’ Connector, Male, Pin Type
NOTICE
The Society of Cable Telecommunications Engineers (SCTE) Standards are intended to serve the
public interest by providing specifications, test methods and procedures that promote uniformity
of product, interchangeability and ultimately the long term reliability of broadband
communications facilities. These documents shall not in any way preclude any member or nonmember of SCTE from manufacturing or selling products not conforming to such documents, nor
shall the existence of such standards preclude their voluntary use by those other than SCTE
members, whether used domestically or internationally.
SCTE assumes no obligations or liability whatsoever to any party who may adopt the Standards.
Such adopting party assumes all risks associated with adoption of these Standards, and accepts
full responsibility for any damage and/or claims arising from the adoption of such Standards.
Attention is called to the possibility that implementation of this standard may require the use of
subject matter covered by patent rights. By publication of this standard, no position is taken with
respect to the existence or validity of any patent rights in connection therewith. SCTE shall not
be responsible for identifying patents for which a license may be required or for conducting
inquiries into the legal validity or scope of those patents that are brought to its attention.
Patent holders who believe that they hold patents which are essential to the implementation of
this standard have been requested to provide information about those patents and any related
licensing terms and conditions. Any such declarations made before or after publication of this
document are available on the SCTE web site at http://www.scte.org.

SCOPE
The purpose of this document is to specify requirements for indoor male “F” pin type
connectors that are used on ANSI/SCTE 117 2010 and SCTE IPS SP 009 mini coaxial
cable in the 75 ohm RF broadband communications industry.
All requirements of this document are measured after installation per manufacturers
instructions of the cable into the connector.

DEFINITIONS AND ACRONYMS
2.1
Dielectric: The material that is used to insulate the center conductor contact from
the outer housing.
2.2
Center Conductor: The pin conductor inside the male “F” pin type connector that
accepts the coaxial cable center conductor and contacts the “F” female socket of
the mating connector.
2.3
Reference Plane: The reference plane on the male “F” pin type connector is the
mating surface that seats against the female F port. It is also the plane from where
all horizontal dimensions are taken.
