FACT: The MFJ-1708SDR Transmit/Receive switch will degrade your receivers' performance and significantly hurt your ability to work weak DX Stations. Using a Signal Generator, Oscilloscope, T Connector & Reference Grade Minicircuits ZSC-2-2+ Power Splitter, I conclusively prove the MFJ-1708SDR will hurt the performance of both your main receiver and SDR. Watch the video for a full explanation why, and how an antenna should be split, I recommend watching the video on youtube so you can read the description: I also explain how to get the most of the MFJ-1708SDR if you own one. 73, Jarrad VK3BL
Here is a great graph showing the signal loss of mismatched receivers connected to a parallel 'T Connector' style device like the MFJ-1708SDR: https://drive.google.com/file/d/1r61IoHewQKbJlszmbOdFpXVIoXqitovw/view
