Well the tower is close to the house, so I could climb the tower and stands safely on the roof to work on the dish. My only question is if the wind picks up, will the tower sway enough that I loose signal. I can't put the dish on the ground because there are trees in the way.You can, if you want to climb a tower every time you need to work on your dish! I'd put it on the ground if at all possible, it's really tough to work on those things when they're off the ground, and you're hanging from a tower or ladder.
I was reading in another thread about the M1 and M2 systems from Sadoun, will the better choice be the M2 for the LNB?
