The 4O3A AB Switch Relay is a high isolation A/B switch, needed for some applications such as extension of an antenna matrix.
The most common use case is routing the antenna between two existing high isolation antenna switches, so the isolation of this A/B Relay isn't quite as high as the RS3000 or 1A2R.
Additional isolation is realized by grounding of the unused port.
AB switch is powered by 13-15V through a dedicated power connector. It has an LED to indicate "out B" status. When powered off the input is routed to out A.
