A good friend of mine is currently building a very large home. He wanted to take on installing all the home automation and wiring like cat6a, speaker wires everywhere, alarm, rg6, etc. I am familiar with the swm setups. I have a self installed swm 16 with a hr34, hr24, and an old hr21. But his install is on a whole new level. He will have 21 hi def tvs. He feels he will not need very many DVR tuners since they do not record much at all. But I suggested if possible putting a hr34 in 2 locations and regular hd receivers in the others. With all that said, can anyone give some general input or specifics on the following? 1) wiring considerations for this setup. I already told him to run 4 feeds from sw corner of house to media closet. He will have 3 cat6a lines at each location plus 2 rg6 lines. 2). What kind of swm setup would work for 21 tvs? Any preferred setups? 3) he will be new to directv. At input on account setup etc? Is this in the level where he may need some kind of commercial account?
