I thought that the Diseqc 1.2 mount is universal, meaning it should work regardless your location. Anyways, back to your questions, I have not seen any formular for "tweaking" the mount to make the dish movement more flat/curve. The only thing I know is the curve of the arc depends on the declination, in this case, use an incorrect h-h mount elevation to make the dish moves the way to want (more flat).
Check out the link below, it's for
C-band setup, scroll down the bottom of the page, you'll see the box "Philosophi of Tuning Dish to Sat Arc"

It's perfect info for what you are trying to accomplish.

The problem I'm having is "This far south, requires a very large arc. If I set up with the standard due south 0 degree reference, I run out of travel on my setup before getting to the two echostar birds.
From my location:
Azimuth to 110 is 108.3 degrees true.
Elevation to 110 is 33.9 degrees.
Azimuth to 119 is 114.5 degrees true.
Elevation to 119 is 42.6 degrees.
Heres the question:
Is there any way I can set up with the zero reference of my motor at 114.5 degrees (119 satellite) and arc correctly to the 110 satellite to the east?
The standard motor elevation for my latitude is not going to work, since the elevation angle change is 6.2 degrees between the two birds. Over the short azimuth change between the two birds, the elevation is only going to drop a degree or two with the normal latitude angle set on the motor. I'm sure it's possible if enough tweaking is done with the motor elevation and possibly moving the basic mount from vertical. However, I'd like to know if anyone has figured out any kind of formula, so I don't have to spend days working it out with trial and error.
Thanks in advance! |
