The passive resistive power dividers will only provide 6 dB of

The stridsberg ones aren't resistive -- they're transformers and
provide 20dB isolation. I assume the I.C.E. ones are as well, but
don't have any firsthand experience with them.

I use a Stridsberg 2-way splitter to feed two Stridsberg 4 way
splitters, all passive. That's a fair amount of signal reduction to
each receiver, but with my antennas I'm well above the noise level. I
don't have any loops or other low-output antennas.

The Stridsbergs are just repackaged Mini-circuits transformers. You
can buy them from Mini-circuits for much lower prices, and they don't
mind qty 1 orders. The real trick is figuring out their catalog...

http://www.mini-circuits.com/


For an 8-way splitter, which is what I'd do if I could do it from
scratch, I'd use the ZCSC-8-1 on page 139 of their catalog.

For a 4-way splitter, I'd use a ZBSC-4-1... other various case styles
are available.

For a 2-way, I'use a ZSC-2-1.

If the Mini-circuits catalog intimidates you, go for the Stridsbergs.
The passive ones work well... I didn't want the active ones because I
was concerned about IMD products being generated in the preamp.

Good luck!
