I have a one recvr install in a 20 story building. getting cable from the 5th floor to the first is not an issue. The issue is the mst 774 and 2 swm 8 modules. Do I need to put my own swm 8 module in or can I use a port directly off of the mst 774. I have no way of knowing if there are 8 tuners running off of each of the existing swm 8's, which would make putting a 2 way swm splitter on there a bad idea. Can I plug one line for an h24 directly into the mst 774 or do I have to use a swm 8 module?
