My father in law recently had E installed and I had some questions about the way the installer set things up.
He got a 921, 811, and 510. His new house has a great home networking setup. He has 4 coax runs going to the spot where his dish was to be placed. These 4 runs then go to a main box in the house where they can then be fed into the rooms that he wants. Each spot in the rooms then has 2 coax feeds coming into it.
The way the installer then set up his receivers is as such. The installers set up a dish with a dual dp lnb. The dual lnb then runs on 2 coax lines to the main box. Then at the main box the installer had those 2 lines feed into a Dp34 switch. Then the 4 outputs from the dp34 switch fed to the receivers, 2 to the 921 and 1 each to the 811 and 510.
Right next to the dish he also set up an ota antenna. This went to the main box with 1 coax. Then at the box he split the antenna signal and used a diplexor to feed it to the 921 and 811, after those lines came out of the dp34.
While all of the receives worked fined, the 921 and 811 were unable to pick up any ota hd stations. I figured the problem could be from the long cable run plus the use of diplexors. So I ran a cable directly from the antenna and into the 921 and we were able to pick up some hd stations.
My questions was why use a dual lnb and a dp34 rather than simply using a quad lnb. If he was limited to only 2 coax runs coming from the side of the house then that would make sense, but since he had 4 coax lines to work with I was confused by the choice. Plus he could have just as easily used diplexors right there by the dish and antenna to send the antenna signal to the to the two lines going to the 811 and 921.
My father in law said that he was charged like an extra $110 for the switch, so I wondered if maybe that had something to do with the installer's decision making process.
Wouldn't it be cheaper and easier to just use a quad lnb for this setup? Plus, wouldn't Dish give a free quad lnb for a customer setting up an account with this many receivers?
I would appreciate anybody's thoughts or insight into this setup. Thanks.
