I do receive sats in the following order

Hotbird(13)--Arabsat2(26)--PAS10(68.5)--Thaicom(78.5)--Insat2E(83)--Asiasat2(100.5)--Asiasat3S(105.5)

but I do not receive EutelsatW2(16)--Paksat1(38)--NSS703(57)--NSS6(95)


WHY?

Are they not located in the same arc?

What adjustment should I make....Should I lower the dish or move it up?

THANKS
