[QUOTE="Old Satellite, post: 15057, member: 175277"] I can confirm that a high quality 1.8 -2.0 mtr will generally provide good results on c band the primary exceptions will be on the global c band beams. Please note that while the IRTE is light this is also equally a problem when the dish is subjected to windy conditions, along with the petal construction, this often results in some flexing of the dish surface this reduces the effective gain of the dish. This is one of the primary reasons for the reccomedations you have seen earlier. The ku band performace can be improved by removing the 90 degree Elbow and fitting the lnb directly at 90 degree to the corotor (out of the side) the gain achieved is around 2.0-3.0 db this is a direct result of reducing the path of the signal to the lnb 12 ghz signals do not like to be bent 90 degrees! the additional area of the lnb is very small with most newer lnb's and the gain / versus loss of recieving area of the dish masked by the lnb is very small. you can also fit the ADI corotor whcih has an additional gain in both c and ku of around 1.0 db as a result of the cast in dielectric plate. It is quite possible to achieve simlar performace to the KTI in KU band with a high quality solid 1.8 , the c band will be weaker however. Regards Old satellite [/QUOTE]
