    I'm sure the diplexers cost more than the splitters. And a set of splitters work fine.

    All unpowered splitters are at least -3db, because -3db is 1/2 the power of a 0db signal. Since the signal is split into two parts, each has half the power, or -3db.

    Of course splitters aren't perfect, so the actual losses are higher, such as -3.5 db. If you have a choice, get one that's as close to -3db as you can.

    As for splitter vs diplexer, a real diplexer is actually be a band-splitter... they pass all the frequencies that are antenna freqs out one port, the satellite band out the other port. These have lower insertion losses. Whether or not what you buy is actually that, or just a splitter, who knows?

    One question I have: if you're using one of the single-coax solutions E* provides, will a stock splitter (or diplexer, for that matter) still work? I don't know what band the second 'virtual' coax signal is translated to, but it could well be above 1Ghz. (Or in the OTA band, for that matter)
