I have now an AR 8600 Mk2. I have an SA7000 that I am using for it, but lets be honest, for HF and below frequenices, nothing beats a longwire. I want to find a duplexer that will split the input into input from the SA7000 from roughly 30 Mhz and above and this take input from a longwire from roughly 30 Mhz and below. Can someone recommend a setup? Thanks!!
