Edit- I was able to come up with a solution. Thanks for everybody who messaged trying to help.
Just wondering if anybody has old Bell (or Dish Network) hardware kicking around that they want to get rid of? I need a single LNB; like the one shown in this Amazon listing:
https://www.amazon.ca/LEGACY-LNBF-OR...dp/B002N4ROYG/
It is the one that would connect to the end of the "Y" adapter for the two satellites.
Back story for those curious, I went and re-activated one of my old receivers to use at the trailer. Those familiar with Bell will know you need to keep the receiver active all the time or you will lose channels; so I bring it home when I'm not at the trailer. However my dish at home has DPP hardware, so I have to do a "check switch" test every time I take it back and forth. Minor annoyance; and very much a first world problem. However I would also like to make it more user friendly for my family in case they go out without me.
