Good find! - :up
Even got the original pole 'n concrete.
Just use a post hole digger, and drop the whole thing right back into the ground.
Depending on soil conditions, I might not even pour in more (but it couldn't hurt)
Just true up the top of the pole (looks like it's got a kink near the bottom).
The feedhorn matches to the elliptical dish, very well.
If you need any help with the LNB, look up "dove bar".
We have are some good pictures of it and info on how to adjust it (for skew).
edit:
Come to think of it, if the dish's mount will skew, that's the proper way to do it.
Set the LNB to zero, and skew the mount.
PS: DishStore (gold sponsor, top of this page) has a 3x4 multiswitch for $5, if you don't have one.
