As I recall, this topic has been addressed here before, but evidently I 
did not save those threads.

I'm interested in buying/building a 1 in >=4 out receiver coupler, HF 
only, receive only, >=0dB gain per port relative to the incoming antenna 
signal.

I'd greatly prefer broadband, but I could live with tunable if that's 
the only practical way to go.

As I recall (???), such units have existed in the mil surplus market, 
but they are very rare today.

I'd be happy to build something, either tube or solid state, if anyone 
has a know-good design.

Any and all advise will be welcomed.

Thanks in advance for the help!

Mike, WB5MYY



PS - If you get a dupe post on this, my apologies, I had an email client
