1. Scope
The purpose of this specification is to specify requirements of the Male “F” Terminators that are used on “F” ports as specified in ANSI/SCTE 01 2015 and ANSI/SCTE 02 2015. This specification is not
intended to limit or restrict any manufacturers from innovative designs and product improvements.

4. Compliance Notation
shall This word or the adjective “required” means that the item is an absolute requirement of this specification. shall not This phrase means that the item is an absolute prohibition of this specification. forbidden This word means the value specified shall never be used. should This word or the adjective “recommended” means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications should be understood and the case carefully weighted before choosing a different course. should not This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label. may This word or the adjective “optional” means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item. deprecated Use is permissible for legacy purposes only. Deprecated features may be removed from future versions of the standard. Implementations should avoid use of deprecated features.
5. Definitions
5.1. Definitions
Dielectric The material that is used to insulate the center conductor from contacting the outer housing. Thread Relief A reduced diameter section of the threaded surface to allow the tool to run out. This feature is optional. Center Conductor The inner conductor of a coaxial cable or pin of a male “F” connector. Reference Plane The reference plane on the male “F” connector is the mating surface that seats against the female “F” port. It is also the plane from where all horizontal dimensions are taken.
6. Electric Requirements
6.1. Bandwidth
Shall be a minimum of 5 MHz to 1,002 MHz, unless otherwise specified.
6.2. Impedance
Shall be 75 ohms nominal.
6.3. Return Loss
Shall be 25 dB, when tested in accordance to ANSI/SCTE 144 2012, Test Procedure for Measuring Transmission and Reflection.
6.4. Shielding Effectiveness
Shall be a minimum of 100 dB, when tested in accordance with ANSI/SCTE 48-1 2015, Test Method for Measuring Shielding Effectiveness of Passive and Active Devices Using a GTEM Cell.
7. Mechanical
7.1. Physical dimensions
The recommended physical dimensions for the male “F” terminator shall be as specified in Figure 1,
