I think I get what your your after.
You want a 3 lnb unit which is what your looking at from the link.
Do you have a receiver then ?
I take and use my receiver from my shop and use a used take off dish I got from an installer .
Then I mounted my dish on a work light stand.
One suggestion I would recommend would be this . Tailgater portable
Search (dish tailgater) in eBay.
Auto tuning dish is a lot easier for someone starting out.
