Dish size for transponder on 53 east

Can't receive transponder 12669V on 53 east properly, signal comes and goes.What size dish would I require for my locality ie what are members near me using for this. Thankyou all.

Well how can I receive most transponders off steerable beam 2?

The image link you gave is for steerable beam 1 not 2. Steerable beam 1 is not possible at all I agree.

OK,this is what I scanned on 12669v,feed-2,Jsc-feed,test-1,ch1-scr,ch2-scr,test2,test3,art-feed,orbitline 1 through to 3,feed-4,test-5. Also on other transponders on steerable beam 2I will give you a few, 12.648H scope tv,12.562 win tv,12.640 al anbar,12.633h salam tv,12.653h default(whatever that is),etc etc.

These signals are not that strong (well some anyway). Heavy low cloud and or heavy rain will cause no locking ie no sig. this way.
