Determining Elevation

[mjamm]

I have a dish where the elevations have been sanded off??? Without that, can I just assume at 0 degrees the LNB arm is level and I can adjust the arm up to my 36 degrees?

Thanks in advance!

No. The LNBs are offset from the axis of the dish by say 15 deg, not verified. That means when the dish is vertical, i.e., pointed at the horizon you are by reflection looking upward (elevation) by 15 deg. I have one left over for 61.5 and it is near vertical--great for shedding snow--and looks like I am pointed and the neighbors lower wall. In fact, it just barely cleared his chimney from my deck. So a level arm would be an elevation of 30 degrees, perhaps.

Buy a new dish, they are rather cheap. Or find one junked or ask your friendly dealer if he has a surplus one.

You will want an arm with 1, 2, or 3 LNB holders as needed, 300/500 one-eye (I-beam), 500 two-eye, 1000.2, or 1000.4.
