I have difficult to buy  80 / 100 cm satellite dish  and I see very seldom on thai roofs
Nor Lazada or Aliexpress sell it

Yes 80-100cm  seems not so popular 

 

maybe go a bit bigger  C band dish  starting at 135cm

There is heavy rainfall in Thailand which makes the small ku band less than ideal (although pay for service still use them).  For most people better to have C-band system if you have the room and they provide hundreds of free channels.
