this whole thread is confusing me the more i look at it. like the wiring diagram used. now there are dpp 500+ lnbs so no switch is needed. but if you have a line of sight issue on your old 1000+ setup using an old lnb then just don't hook up the lnb output of the satellite with no line of sight to the switch and instead hook the wing dish to that port on the switch. In no way do you need 5 sats. Either 110, 118, 119 and 129 or 61.5, 72.7 and 77. Or if you get special programming from 118 and need an eastern arc setup for your locals then use a 1000.4 to 61.5, 72.7 and 77 and hook in 118 to the LNB IN port on the 1000.4. Remember on a DPP 500+ lnb you need a dpp44 switch to shut off the internal switch of the dpp 500+ lnb and the 1000.4 lnb so that would be cabled as such---1000.4 #1 72.7, #2 61.5, #3 77 and then cable from port #3 on the dpp 500+ lnb for 118 and then on the dpp 44 switch from inputs top to bottom --- top 72.7, then 61.5, 77 and then 118. If you cable this setup correctly you will successfully shut the internal switches inside the lnbs off and will not have any problems.
