Was wondering, if I bring my Astro Byond decoder + an active smart card (legal one), can I watch Astro from Bangkok?

What else do I need?

I know I will need a satellite dish, but what kind and what size of dish?

I was told Ku Band Dish should be sufficient, but from the
[ http://www.satbeams.com/footprints ]
it shows that I will need a C Band Dish with

[ Reception details
EIRP level = 40 dBW
Recommended dish size = 150cm / 59.1in ]

but I also read somewhere that our Astro Byond decoder are not compatible with C-Band dish?

Can some one help me?
