Open Box MFJ-1708B-SDRS SDR RF Sensing T/R Switch with SMA Female SN165149
RF Sensed TR Switches with a receive splitter designed to be used with a transceiver and a separate receiver such as the popular SDR receivers. The Splitter gives high isolation between the transceiver and SDR Receive port to reduce crosstalk and interference between the two ports. The SDR port has a protection circuit to help prevent damage from transmit RF. Has an SMA connector for ease of connection to SDR dongle receivers.
