I use a tripod mounted HD dish and the H24 box I take from my home when on the road in the MH. It works fine. The first time I set it up I did it while the MH was parked in front of my house. I have used this set up from CA to Montana. I essentially keep the same setting on the dish, then fine tune at each new camp. The Sat finder that comes with the package, while looking cheap, works fine. Recently, Directv made some changes in the satellite drop down menu when you are doing the set up procedure. I had a heck of a time getting my system to work after that. Finally, someone on the directv forum had me try going to "multi" first before choosing dish type. That provides power to the sat finder, and for some reason doing it that way solved my problems. Tip- go to Walmart and for ,$1 each buy a bunch of tent stakes. That helps secure the tripod so it doesnt move in a strong wind. Works for me.
PS, my guess is that you will need a B-converter. When you make the dish choice on set up, it will tell you.
