That diagram doesn't really make sense for your install. If the node and the home runs are all in your utility room then you wouldn't use a tap. The Hopper would be connected to Host port and the Joeys would be split off the Client side of the node. In any case I would agree that your best bet...

Actually another dish would work. 2 1000.2 dishes with 2 lines each to 2 solo nodes. Or one dish and 2 44 switches and 2 solo nodes. Obviously the dual node would be infinitely better as the systems would be essentially seperate and joeys couldn't be switched from hopper to hopper...oh, and you...
