Dish Net work dual tuners, on TV2 is a UHF remote, inorder to be used in anither room. The signal is sometimes interferred with.
We hace found a solution to this, by using 2 2way splitters.
On the back of the receiver. run a piece of coax from TV2 out & a piece from UHF antenna to the in ports of a 2way splitter. From the in port run the cable to the other room.
In the other room, connect the cablr to the in port of a 2way splitter. The out ports, one to the TV, the other connect the UHF antenna.
This has even enabled us to use TV2 in a Machine shop.
Hope this will help someone.
