Hey guys,
Just got a NEDSR SDR dongle and was wondering what the best antenna switch would be? I am interested to see what everyone else uses to couple the SDR with a transceiver so the SDR will get switched out of line when transmitting. I saw this MFJ switch and am tempted to buy it unless there is something else that is better. Any and all replies welcome.
