Dish Elevation

[Otter Lake]

First let me wish everyone a Merry Christmas and the best in the New Year.

Have a question about dish elevation. If a dish has an offset angle of lets say 24 degrees, when vertical. Do you factor in this 24 degrees when setting the elevation on the dish. Example when a satellite is at 34 degrees is the elevation scale on the dish set at 10 + 24=30, or do you set the elevation on the dish scale at 34 degrees. Might be a dumb question but am confused on setting dish angles. Thanks

No you do not factor in the offset. If the elevation is 34 degrees, you put it at 34 on the elevation scale. The only time I use the “offset” is if I have to see if I can clear an obstacle. I will put the dish at the normal elevation +22 and see if the LNB clears it (so if its 34, I put the dish at 56 and check first)

With the dish elevation scale set at the 34 degrees tou were discussing , will an angle finder on the back of the dish mount show 34 degrees ?

depends on the dish

My Toroidal T90 does do it correctly but my Fortec does not. It is way off

If you have a smooth lip around the edge of the dish, you can put a magnetic angle finder on the right or left side of the dish and check the alignment. You simply subtract the offset from your elevation. If you don't know the offset then you can use a program such as "Satellite Antenna Alignment".

Enter the height and width and the program will give you the offset.
