lnb/lnbf compatibility?????

[Dover228]

Good morning, I am new to satellite comms and have a simple question. We have 1.2 meter motorized dishes on our comms trucks that auto seek 123. I want to add an lnb with a custom bracket that I fabricate to see 119 when my truck peaks 123. I am envisioning a cylindrical type lnb that I can make a bracket for and then cnc that bracket out of aluminum. The problem i have is I am not sure what kind of lnb to purchase. When I look online or call vendors that have "universal" lnb's for sale, they have disclaimers saying, that it doesn't see circular or linear or stuff like that. I don't understand the language they are referring to. Dish Network is our provider and I am sure their bird speaks a certain language but am not sure what it is. I need a pretty rugged device. thanks in advance for any help.
