RF Distribution Amp/Splitter

[vintage.digi]

I'm looking for advice on my NTSC RF setup and I'm not sure where to turn with this being a dead art.

I'm creating my own playlists that are running into Pico Macom MMA860S RF modulators, and then the output of those is going to a Blonder Tongue output combiner. At this point I have one RF cable with my 4 channels, but that's where I'm not sure what I need next. I want to split the signal to various TVs around my office building.

My office consists of two buildings put together and I would like to have an 8-way splitter in one building daisy-chained to an 8-way splitter in the other building, to simplify runs.

Could anyone give me advice as to the proper way to do this without signal loss, or point me in the right direction to find out?

Thank you!
