ok. some guys at solidsignal said I couldn't do it. However the other guys at weakness said I could. lol
Just trying to get a good answer. lol
I'm sorry you got confusing information. I'll talk to my colleagues and make sure it's a little clearer.
You can add a splitter further down the line from an 8-port splitter under most conditions. Of course you can have no more than 8 tuners on a single SWM leg of a SWM-16 and no more than 8 tuners total on a SWM-8.
If you're not fully using every line coming from your 8-way splitter it might be best to replace it with a 4-way as the signal loss from a 8-way splitter is very great, and that's a good reason not to further split the line.
We've found that MRV problems due to low signal levels in the connected home (550MHz) range are very hard to diagnose and so it's best to avoid over-splitting if possible. I think that's what our tech meant to say to you.
Please let me know if there's anything I can help with.
