This word or the adjective“required” means that the item is an absolute requirement of this specification. This phrase means that the item is an absolute prohibition of this specification. This word means the value specified shall never be used. 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. 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. 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. 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. The material that is used to insulate the center conductor from contacting the outer housing. A reduced diameter section of the threaded surface to allow the tool to run out. This feature is optional. The inner conductor of a coaxial cable or pin of a male“F”connector. 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.ANSI SCTE 148 pdf download.
