We have two Dish 500 dishes (one pointing at 119/110 and one at 61.5) going to a DP34 switch. When our install was done they used the Y/twin LNBF adapters on both of the dishes but the dish pointing at 61.5 only uses a single LNBF. So on the 61.5 dish there's just this big opening at the end of the arm where another LNBF could have gone. Now that I'm looking at it I realize it would be a great place for snow, ice, freezing rain, or insects to start collecting or even build up inside of the arm. Should I ask that a single LNBF adapter replace the one that's there now in order to close up that huge opening? I would have said something earlier but I didn't realize it until after the install was over. I'd hate for it to become a real problem when the weather isn't as nice as it is now or after my service warranty is up. Any thoughts? Thank you.
