DVR 510 P368 service menu

[Jim5506]

I did some searching on the site and found this:
"The new Dish 1000.2 is almost just like the current Dish 1000, it still only picks up 110, 119 and 129. The dish is the same size, however the mast is slightly longer then the current DISH 1000."

It looks like the DISH 500 is what I need for the 921, as I am on 61.5. Can anyone confirm that?
TIA

The 1000.2 is larger that the Dish 1000 by one inch both in height and width, plus it has a built in switch supporting three receivers and an input for a fourth lnb to be connected.
