10、ndard is identical with IEC Publication 169 “Radio-frequency connectors” Part 2:1965 “Coaxial unmatched connector” including Amendment No. 1. It has been prepared under the direction of the Electronic Components Standards Committee. This Part 2 of BS 3041 is a revision of BS 3041:1958 “Television an
11、d VHF broadcast receiving aerial feeder connectors”. Its text is now harmonized with the text adopted by CENELEC. This standard is intended to be read in conjunction with Part 1 of BS 3041. Cross references. For each of the following references to other IEC Publications that are given in the text, t
12、here is an equivalent British Standard; these are as listed below. NOTECable type “96-IEC-50-3-13” is equivalent to cable type URM 43 or URM 76 in BS 2316-3:1969; cable type “96-IEC-75-4-13” is equivalent to cable type URM 90, URM 117 or URM 306 in BS 2316-3:1969. Regarding the references to the IEC
13、 cable types in clause 3 of this standard, see “Textual errors” below. Textual errors. Attention is also drawn to the incorrect use of symbols for dimensions in the figures and tables on pages 1 to 4, and for the variable force in 3.2 on page 5. In accordance with 1SO 31/0, these symbols should be p
