I'm sure the LNBF cluster would not be properly aligned and would require modifying the SuperDish arm to get the 1000.2 LNBF in the proper position. Something like some have done using the Dish 500+ LNBF Cluster on a SuperDish 121.
The 1000.2 cluster has a built in switch to feed 3 dual tuner receivers. There would be no need for a DP34 switch unless you wanted to feed 4 single tuner receivers. So then you would need a DPP44 which would allow you to feed 4 dual tuner receivers or 4 single tuner receivers, or any combination.
So what are you really trying to do, remove Sat 121 and add Sat 129 in its place?
If so....
- Option 1: The easiest way is to order a SuperDish 121 Repoint Kit from The Dish Store for $99. It is on their home page,
The Dish Store - Powered by Metro25, as a SuperDish 121 to 118.7 Conversion Kit.
Then use your DP34 Switch, your 110 Dual LNBF, the Kit, and you should be able to receive 110, 119, 129, and if you swap the DP34 with a DPP44, you will also get 118.7.
- Option 2: Another low cost way is to buy a $35 DP Dual LNBF and duct tape it to the side of the SuperDish 121 cluster. I've done this, but every month I needed to tighten up the duct tape which weakened do to the sun.
EDIT:
I guess Option 1 would be converting a SuperDish 121 (or 105) to either a Dish 500+ or Dish 1000+.
I wonder how Dish records such setup in a Customers Account?
