One thing that should be mentioned is the type of dish that you purchase. A single LNB dish will get you limited DirecTV programming. The slimline 5 LNB oval dish will get you everything, including all of the HD channels, BUT, it is difficult to aim manually. A 3 LNB(if I remember right), will get you most all of the main DirecTV channels and is still fairly easy to aim.
Ok a few corrections are needed to the above post.
A single LNB dish from Directv will get you all the Standard def. stations.
A triple lnb aka "Phase III" dish will 3 LNB's for the 101, 110, 119 satellites. This is only needed for people wanting only Standard def plus foreign broadcast, also so limited areas still have there locals stations broadcast on the 119 satellite, these are being moved off of the 119 as quickly as Directv can make the change and deliver the new receivers to customers in those areas. Basically it is a very limited use dish that is being eliminated.
The Slimline 5 dish is only needed if you want HD & Foreign language stations. The 110-119 satellites carry foreign language now "NO" HD broadcasting. This dish only has 3 lnb heads but actually receives 5 different satellites. (3 LNB's in one head 99,101,103 and 110,119 on the other 2)
The Slimline 3 dish will get you all the Standard def programs and all the HD programs, the only items that it will not receive is those local programs that are still on the 119 and foreign programing. This is not a concern to RV use unless you want the foreign programs. You can not subscribe to local programing that is located on the 119 satellite anymore, Directv is busy moving everyone off of it. The Slimline 3 dish has 1 LNB for 99,101,103 satellites.
Here is a picture of a Directv LNB for standard def reception on the 101 satellite.
Here is a picture of a Directv Phase III LNB for 101, 110, 119 satellites
Here is a picture of a Directv Slimline 5 LNB 99,101,103, 110,119 satellites
Here is a picture of a Directv Slimline 3 LNB 99,101,103 satellites
Dish Network has a variety of different dishes and LNB's like Directv does. If any one needs pictures to identify those as well, I can post them.
Now for those of you that wonder why it is so easy to lock onto the wrong satellite while trying to setup your dish this picture from the NASA website of all the satellites that are in orbit at the elevation this picture was taken from.
This picture was taken from even deeper in space showing even more satellites
