has anyone done a signal loss test with any of these switches? I'm at the low end of the signal spectrum (southern exposure), so a unit that has a 6db loss as opposed to 3db loss is significant to me.
and there IS a difference with these things, as I found out implementing a UHF/SAT combiner. One unit padded down the signal enough so there was NO signal.
Powered Multiswitches are designed to actually boost the signal a little (~1.5dB) to overcome insertion (connection) losses. If decent cables and F connectors are used your net effect should be always positive with a bit better signal at the reciever.
