By tweaking I mean improving the dish surface and maybe improving of the focal point of the feedhorn. You havent as yet confirmed what type of dish you have (nor how old it is ) . A change of LNB is not the best thing to do first of all.
ok, it is a fortec 1.6m dish, only 1 year old, any help? also i have bought a new lnb a 0.2, before i had a 0.3 and suddenly i get a little, very small, recpetion now on sirius during the night so i thought if i can get the best lnb i might be ok?
ok well i will buy the lnb you suggested "C120 Universal LNB is Invacom Twin" as i can now see the picture on the channles i want but it just cracks at times so i only need 5 perecnt more signal, do you think that lnb can help me?
