Anyone try to get the Measat 1, Telkom, Thanicom 2/3 & Palapa C2 C band signal signal using 120 cm prime solid ?

I tried whole today but no result although can get asiasat 2/3. Az/El , stb settings are correct but I am not sure whether dish too small or LNB polarization problem…..

Appreciate those tried to share opinion. Or any web for reference ?
