Radar antenna slip ring RJ02-571-010

aluminummulti-channelwith RF coaxial connector

Short description
This dual-channel coaxial RF rotary joint RJ02-571-010 is designed for stable transmission of RF signals in rotating systems. It provides low insertion loss, controlled VSWR and phase stability across DC–4.5 GHz and supports DC power transfer as specified, making it suitable for rotating antennas, radar feeds and other rotating RF assemblies.
