147427 Dish500 Plus Lnb Question.

[mmkk]

I am located in the Caribbean islands. Right now I have a 1.8meter channel master dish pointing to 61.5 with a legacy lnb, 2nd 1.2meter channel master pointing to 119 with legacy lnb and 3rd 1.2meter channel master pointing to 110 with legacy lnb. They are connected to SW64 switch feeding 4 dishnetwork recievrs( 2- 501 and 2 - 301.10).
I saw the new 147427 Dish500Plus LNB Block Assy on this site. Is it possible to use this LNB on 1.8 meter(6 foot) channel master dish and pick up 118,119 and 110 at the same time using DP34 switch and feeding the 4 recivers that I have. Please let me know what are my chances or is there any other alternative to pick up all from 1 dish.
thanks a lot,
mmkk.
