I want help from from anyone with time to measure their flat rimmed VSAT dish dimensions, so as to help verify one of my web page calculators.

See bottom of page http://www.satsig.net/pointing/finding-dish-offset-angle.htm

You need to use tight crossed fishing lines and measure:
Vertical diameter of dish (mm)
Sideways diameter of dish (mm)
Maximum depth of dish (mm), measured to 0.1mm accuracy if possible.

Questions:
Do the calculated results regarding focus position match your measurements ?
Is the accuracy required impractical to achieve ?

Best regards, Eric.
