How can I put this delicately . . . ?
Is your 1.0 m dish a molded commercial one like a Prodelin or Primestar (ChannelMaster)?
And is your 36" dish an imported metal dish?
The commercial 1.0m dishes are 1.0 m wide and a little bit taller (maybe 43"?).
The imported metal 36" dishes are 36" tall, and less-wide than 36.
So, you're sort of comparing apples to oranges, if that's what you have.
disclaimer:
the GeoSatPro 1.2m metal dish is sized "larger", see
specs
and the Fortec Star 1.2m metal dish is "larger", as
well.
so don't assume... it's always best to verify each dish individually.
