The passive resistive power dividers will only provide 6 dB of isolation. 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! -- Eric F.
