On mine, I've got output to the first splitter, then from one is hooked up to a device and the other to another splitter, then next one is hooked so another device and the other to another splitter, and so on. In all, I've got 4 splitters. None of my devices suffer any signal loss.
There's always signal loss in splitters but this is compensated for by the amplifier. Every 2-way splitter loses at least 3.5db (just more than half the signal) on each output. Every 4-way splitter at least 7db,.....and so on. You can't build a splitter that does not have that signal loss. So an 8-way splitter loses at least 10.5db on each output and you have to compensate for that by amplifying at least 10.5db.

If you have a preamp at your antenna you may not need any additional amplification - in fact it is best avoided, because you can get overload at the receiver and it can make your signal worse rather than better. Start by just trying a simple 8-way splitter. If the signal is too weak, look at buying a decent distribution amplifier.
Here's a very basic article about OTA signal amplification and splitting. http://www.tvantenna.com/support/tut...mplifiers.html
