Both the mini-circuits and stridsberg splitters (which are made with
mini-circuits component splitters) provide over 20dB isolation between
the radios and just over 3dB loss of signal.
I know from where I speak -- I use stridsberg splitters, mini-circuits
splitter boxes and mini-circuits component splitters. The breakdown is
as follows:
1 mini-circuits microwave splitter
1 stridsberg 4-way V/UHF splitter
2 stridsberg 2-way V/UHF splitters
2 stridsberg 4-way HF splitters
2 stridsberg 2-way HF splitters
1 mini-circuits HF splitter transformer in a phasing box I built.
