EIA flange RF connectors are used to connect two items of high power Radio frequency rigid or semi-rigid (flexline) transmission line. One side of the connection is denoted as a male connection, or bullet, while the other side is denoted as the female connection, or cup. The flange design, inner and outer conductor dimensions are standardized, by EIA, in the RS-225, 50Ω (ohm), and RS-259, 75Ω, standards. Sizes covered under these two standards range from 3/8 to 6 1/8 inch outside diameter (OD) for 50 ohm and 3/8 to 3 1/8 inch OD for 75 ohm.

The corresponding European standard is IEC 60339-1 and 60339-2. These standards are more complete as they include many sizes that are missing in the EIA standards.

Many years ago, the two RS standards were considered obsolete by EIA. Only until recently has (2007) there been an effort by manufacturers in the US to update these standards.

Many of these sizes are also interchangeable with RF Connectors defined by the US military in MIL-DTL-24044B General and MIL-DTL-24044B Details.
