Active antenna splitter. No power supply but pulled from a fully functioning system. Power supply was lost in transition. I believe these are cross compatible with newer g series microphones as long as they are in the allowable frequency band.
The ASP 2 passive RF antenna splitter has been designed for routing antenna signals to several receivers in a multi-channel system, i.e. up to four diversity receivers are supplied with the signals of only two antennas. The antenna splitter incorporates DC distribution for powering up to four receivers in addition to two antenna boosters via a single mains unit.
By linking two ASP 2 antenna splitters, an 8-channel system can be operated with only two antennas. By using the GA 2 rack adapter, two antenna splitters or one antenna splitter and one rack-mount receive
