SO is the current set up 2way >4 way > 2 way?
your set up looks good, although I dont like to split after an 8 way
what are your cable lengths?
Currently, the coax from the satellite goes to a 4 way splitter. 3 of the 4 connectors go to receivers. 1 of the connectors goes to the "power to swm" on the power inverter. Then "To IRD" is connected to a 2 way splitter and the remaining two receivers are connected to the OUT connectors on the 2 way receiver. The line to the HR-34 700 comes from the 4 way spitter and then goes to a 2 way splitter. One of the OUT connectors goes to the DECA and the other OUT connector goes to the HR-34.
All of this happens in a closet with a Control4 system and a rack. Then, from that closet, the coax goes to whatever room the TVs are in. I've no idea of their length but the closet is in the basement and then there is a main and second floor above that.
Finally, I have 4 other occasionally used TV's which receive cable TV. I am eventually wanting to get rid of that and add the additional TVs to the DirecTV system.
