I found these DirecTV splitters to be excellent build quality with very good loss and bandwidth characteristics Bandwidth. I don't use splitters for DirecTV, but to distribute terrestrial television with MoCA network (D-band, between 1150 and 1500 MHz) in the house. I installed something very similar at my mother in law's house and used a DC feedthrough to power the preamp on the antenna mast. Anything that requires the use of quad shielded RG6 coaxial cable will do a great job with these splitters.
