Got this map from KVH.com
I haven't talked to anyone yet who has tried to get a KA signal outside of the footprint, but lots of ppl outside of the footprint have had success with the KU signal off the 101 sat ( Southern Mexico, Central America ) using larger dishes.
My uncles ex-father-in-law had a place in the Turks and Caicos islands, he got a signal off the 101 sat using a larger dish he bought here in the states, that is the furthest East in the Caribbean I have heard of getting a signal besides Puerto Rico.
sandycody you could try it, there used to be a website for aiming dishes outside of the U.S., but I can't find it now, good luck.
