That LNB possibly won't work, although maybe. If you run port 1 to input 4 on the 42 switch (port 1 out is the 118), then port 2 to input 1, and the DP singles to inputs 2 and 3 on the switch... possibly, but you're probably better off getting a DPP500+ like in the image I posted.
TBH, you really should upgrade. I mean you're trying to put a mechanical stock 350 in a new Corvette
So I had the hopper 3 delivers it was to late to cancel the order. Spoke to the installer he basically told me I need the 1000.2 dish. I also need the hybrid lnb for western ( not sure which one). He also shahid I need a hybrid hud ( not sure which one). He said that way I can use both satellites the 129 in the other patio to receive the 129 which the hub is suppose to help. Then use the 1000.2 for the 110,119. I then called back to get part numbers I didn’t get the proper help. I live in Canada and currently using the regular hopper. I moved for work reasons. He told me the lnb need to have a line in which will bypass the 42 switch I don’t need anymore per his instructions. I would appreciate all the help and solution if one is available. Thank you for your time.
