I'm looking for a HF (500Khz to 50MHz or so) multicoupler/ antenna-splitter
that would allow mulipler receivers to use the same antenna with little or
no signal loss or interaction.

Ideally, this unit would have SO-239 connectors. Number of outputs would be
4 at a minimum, more is better. Will consider active or passive units.

Thanks


Mini-circuits has them.

4-way passive:

8-way passive:

On HF, noise is the limiting factor, so if you still have the S-meter
moving above where it is when nothing is connected when you insert the
8-way splitter, you haven't lost much. (Yes, Nf, but is that really
relevent here?)

Don't know how to read the charts? Call Mini-Circuits -- they happily
do quantity 1 orders and have been helpful when I've dealt with them.

(Mini-circuits modules are what you find inside Stridsberg splitters.
I don't know about ICE, but they are a reputable company, so you
should get good quality whatever they do.)
