I am a new installer with a dish authorized contractor. I have no problems until i get either to expensive homes or commercial units. In either case I only have problems when installing a duo receiver/receivers in a central location; away from the tvs. My problem is with the remote antennas. I know how to make tv 1 uhf...i just need some suggestions on where relocate the antenna so it will work better...or maybe if its possible to split the antenna output and put multiple antennas in the home or commercial building. BTW i know how to use splitters to put the remote behind tv2 for tv2s that are far away from the receiver. Just doesn't work when you need tv1 to work off the antenna too. Thanks for any help.
