How I use the DX Engineering RTR-1A to share a common antenna.

I receive a lot of questions regarding my setup on this YouTube Video where I show how I use my SDRPplay SDR receiver as a panadapter for my Kenwood TS-590.
I use a DX Engineering RTR-1A Receive Antenna Interface to switch the antenna between the main transceiver and the SDR receiver and a Mini Circuits ZFSC-2-4+ Splitter to share the antenna between the SDR receiver and the RX antenne input on the main transceiver.
The drawing below shows how I have hooked everything up.
